Causes and types of defects

The most common types of bicycle wheel defects are figure eight and egg. The occurrence of deformations is facilitated by the active use of the vehicle and intensive driving on uneven bumpy roads.

You can identify and correct these types of deformities on your own, without resorting to the help of a qualified specialist. It is quite easy to diagnose the presence of defects. To do this, turn the bike upside down, placing it vertically.

Next, you need to spin the problem wheel by rotating it around the axis. As a rule, the figure eight is visible to the naked eye. If we are talking about a slight deformation during the rotation of the wheel (if the figure eight is not visible, upon first examination), a characteristic clicking sound will be heard.

Defect elimination tools

To repair your vehicle yourself, you will need the following tools:

  • marker or chalk;
  • plastic assemblies for dismantling the tire;
  • spoke wrench.

Deformation elimination algorithm

First you need to determine the problem area as accurately as possible, identifying the lesion focus. Next, you need to find the central wire in the affected area.

Please note: if the figure eight falls to the right side, the first step is to tighten (or loosen) the spoke on the opposite side using a spoke wrench.

fig. 1.

After performing the manipulation (you need to tighten the knitting needle little by little, by about 1/3 of a turn), you must immediately check the result. Next, in the same way, you need to tighten the adjacent knitting needles on the opposite side. The number of key turns for tightening adjacent spokes should be approximately two times less than the central spoke tightened. As you move away from the deformation site, the number of revolutions should gradually decrease in proportion.

fig. 2. Another type of bicycle wheel deformation is the egg type. In this case, the wheel takes on an egg-shape, flattening vertically. Very often this type of deformation is combined with an eight. The situation can be corrected by tightening the knitting needles on both sides. When performing manipulations, you need to ensure that the knitting needles are not too loose or overtightened.

Eight bicycle wheels. determine the exact place

To determine the exact place of the deformation, it is necessary to turn the bike with the wheels towards the top. Next, you need to rotate the problem wheel, gradually bringing a chalk or marker to the spinning rim. Where there is a figure eight, the crayon or marker will touch the rim. These places should be noted. This is how you can determine the problem area. the hearth of the eight.

There is another method for determining the focus of the figure eight using ordinary ear sticks, tape and a marker. To identify the problem area of ​​the rim, you need to stick the ear sticks with adhesive tape on the front fork feathers on both sides. The areas where the ear sticks will come into contact with the rotating rim are problem areas. This is where it will be necessary to tighten or loosen the spokes in accordance with the algorithm described above.

Elimination of the figure eight defect is a simple process, but troublesome, you can cope with it yourself without the help of a specialized specialist. This method is versatile and suitable for different types of bicycles.

Important: after eliminating the defect, it is imperative to check the degree of tightness of all the spokes of the problem rim. It helps you avoid unexpected accidents on the road.

If you still have any questions regarding the method for identifying the problem area and eliminating the deformation, we recommend that you watch the video instruction:

Bicycle wheel figure eight, egg and umbrella fix

Correcting a figure eight and other wheel defects is not difficult, but a very painstaking task. For everything to work out, it takes not so much skill as perseverance and patience. Before you start fixing the eight wheel, prepare the following:

  • The wheel itself. it is better for a beginner first to fix a wheel on which there are one or two eights, otherwise he may get confused;
  • A piece of chalk or white marker. to mark where the curvature is;
  • Spoke wrench. it is important to choose a wrench exactly according to the size of the spoke nipples;
  • Wheel straightening machine. needed only in particularly difficult cases, the wheels on which there are few eights can be corrected without removing the wheel from the bike.

Fixing the figure eight on a bicycle wheel

To find the figure eight, spin the wheel and slowly move the crayon to the wheel rim. As the chalk starts to touch the rim, remove it and the place where it left the mark will show the direction and place of the figure eight.

Next, we begin the correction. weaken the tension of the knitting needles on one side and tighten on the other. But the weakening of the tightening of the knitting needles must be carried out carefully and proportionally, constantly making sure that no egg is formed.

There are several options for eights, then I will describe which knitting needles should be used to fix:

If an eight is formed between two knitting needles, one knitting needle should be slightly tightened, and the other should be loosened by the same amount.

If the figure eight is formed opposite some kind of knitting needle, opposite the figure eight must be tightened by a quarter of a turn, and the adjacent knitting needles should be loosened by one eighth.

The figure eight formed opposite several adjacent knitting needles. you need to tighten the knitting needle located closer to the center of the figure eight stronger than all the others (by half a turn), then. the farther from the central one, the weaker it tightens / looses the rest of the spokes.

After adjusting the rim, we spin the wheel again and check, if the figure eight is gone or decreased, then everything was done correctly, and if the figure eight increased, we return the nipples to their original position. Then you need to carry out the same operations, but vice versa. the knitting needles that you twisted must be unscrewed, and accordingly those that you unscrewed should be tightened.

Fixing an egg on a bicycle wheel

The first step is to find the place where the egg appears. We take the chalk, spin the wheel and slowly bring the chalk to the rim outside the wheel. As soon as the crayon begins to touch the rim, an egg turns out there.

To fix the egg, the knitting needles must be tightened equally on both sides of the rim, otherwise a figure eight may form. The knitting needles located closer to the center of the egg need to be tightened more, it turns out if the central knitting needle is pulled up by half a turn, the adjacent ones need to be tightened only by a quarter of a turn.

Do not be upset if you fail to fix the eight the first time, I repeat, this work requires perseverance. Experience is also important, the more eights you fix, the easier it will be to fix the next.

Umbrella fix

Adjust and install the umbrella gauge on the wheel axle. His feet should touch the rim, and the center mark should be aligned with the wheel axis and touching it.

Next turn the wheel over. Without reconfiguring the umbrella, attach it to the other side of the wheel. If his feet do not touch the rim, and the center indicator is in contact with the axle, then the spokes on this side of the wheel must be tightened. If his feet touch the rim, and the center indicator does not reach the wheel axis, then the spokes on the other side of the rim must be tightened.

Prevent when correcting eights

Do not allow individual spokes to loosen, or they may break while riding. If, after tuning, there are still loose spokes, they should be tightened, and together with them the adjacent ones (but weaker than the previous one), then repeat the wheel tuning.

Do not overtighten the spokes as they may damage the rim. If after tuning the spoke turns out to be overtightened, loosen it and loosen the adjacent spokes (but weaker than the previous one), then repeat the tuning.

Eight and egg removal on a bicycle wheel

Anyone who uses a bicycle for a long time is faced with such a common problem as wheel deformation. And the problem here is not only the quality of your transport. There are various reasons for rim deformation. Of course, if you drive carefully, on smooth surfaces, then you will not face this problem for a long time. But, as everyone knows, cycling is not only riding in the city, it is outings on dirt roads, or even without them. Therefore, you will constantly face the problem of various curvatures. And you need to know, for example, how to fix a figure eight on a bicycle wheel? If you have straight arms, it will not be difficult.

Every self-respecting cyclist carries tools with him, and in this article we will describe in detail the process itself. And also very often there is a kind of curvature of the tire called “egg”. These are two types of breakdowns that occur with frequent cycling and additional stress. We advise you to learn how to repair them yourself and carry tools with you. This way you can avoid spoiled rest due to the inability to correct the defect.

Where did she come from?

Figure eight on a bicycle wheel

So why does the figure eight appear on a bicycle wheel? This is the most common type of breakdown. It arises from a number of external factors. There are different types of stress on the bike. Most of them are the first to be taken by the wheels. Therefore, if you make sharp turns and perform various tricks, your two-wheeled vehicle is subjected to additional forces and at this moment the axial load is applied. The vertical type occurs under the pressure of the mass of the cyclist and transport. And the last type is shear loads. They tend to manifest themselves in the process of acceleration and sharp braking.

Take a crayon and a spoke wrench

If you are already faced with the question of how to straighten a figure eight on a bicycle wheel, then below are tips for you.

So, the figure eight is the curvature of the rim to the left or right. To identify it, just put your bike upside down on the handlebars and spin the wheel. With this type of defect, it will spin unevenly, bending either to the left or to the right. And there is also a test with a crayon: if you bring it to the rim, then when spinning the crayon will leave marks in the place where there is an eight.

Wheel rim curvature

Next, we need tools. The main and only one in most cases is a spoke key. It is important to choose it exactly in size, otherwise it will be impossible to use it. There is another tool for correcting defects. this is a tire straightening machine. But it is used in especially difficult cases when nothing can be fixed with a brace.

So how do you align a figure 8 on a bicycle wheel? By simply tightening the knitting needles at the point of deformation. Suppose that you have already found the place of the bend. On it you need to determine the central spoke. It should be centered on the arc. In the future, we will twist or loosen it and others with a knitting key.

  • If a breakage manifests itself between two knitting needles, you need to tighten one of them with a key by 1/3, and the other also loosen.
  • If the bend took three knitting needles, then you need to tighten the central one, which is in the center of the breakdown, by 1/4, and release the other two, at the edges, by 1/8.
  • If the curvature has occupied several sections, then most of all you need to tighten the central one, by 1/2, two adjacent ones. weaken by 1/4. Tighten the next two, but already by 1/8, and, if necessary, loosen the adjacent ones. Thus, alternating such actions along the entire length of the curvature, you can remove the figure eight on the bicycle wheel.

When repairing the rim, rotate it after each pair of manipulations. If you twist the main bend and loosen the adjacent ones, then spin the tire and do the test. Otherwise, you risk bending the rim in the other direction.

Oh, this is an egg

Now we can talk about this breakdown. This type of deformation occurs when jumping and hitting hard. The shape of the rim stretches out to resemble an egg. Repairing this type of curvature also does not require special skills, but requires perseverance. If you are doing tricks and jumps, you should know how to remove an egg on a bicycle wheel. We need the same set of tools. This is a spoke wrench, and in rare cases a machine.

So, take the chalk and start rolling the tire. There will be a curvature in the place where the crayon left a mark. As in the first case, we need to twist the knitting needles. If in the previous case we alternately released and tightened them, then here we need to tighten the one that is located in the center of the oval by 1/2 turn, and the neighboring ones by 1/4. Tighten the rest of the knitting needles involved in the curvature by 1/8. Don’t worry if you can’t fix the egg on your bike wheel the first time. Check your actions carefully. This is painstaking work that requires perseverance and attentiveness. Show persistence, patience, and you will succeed.

Needle care

If you decide to look after your two-wheeled friend yourself, take the time to check the condition of all the spokes. They should not dangle freely or tighten too much. Otherwise, you risk damaging the rim or puncturing the tube. Sticking out of the rim can be cut with a file.

Checking the condition of the bicycle spokes

With such simple actions, you can remove the defects received during skiing. Every cyclist will tell you what maintenance everyone should be able to do. If you do not want to become a frequent visitor to the services, you should know how to quickly repair a figure eight on a bicycle or align an egg on your own. This will save money, time, and will also help you in difficult situations when you are in the forest, there is no service and you understand that the next 10 km your bike will ride on you.

Good evening. I rode a cool bike. From Europe. Kemmbell. I gave one “smart guy” for repairs. He pulled up the cables. I drove to the robot, the chain fell off the rear derailleur. in the city for repairs. have risen after the devaluation of the hryvnia! I bought a tool and will fix the problem myself. I think the problem is in the rear axle (or deformation) or oval.

Fixing the figure eight and the egg on the wheel

During movement, a bicycle wheel perceives significant loads in all directions. both vertically (the weight of the cyclist) and axially (maneuvers, turns, degrees), as well as transversely (acceleration and deceleration). over, the magnitudes of the efforts taken by the wheel are many times greater than the weight of the wheel itself. Therefore, even if you ride very carefully, defects will still form on the rim. that is, violations of its geometric shape. Of course, if the wheel is assembled correctly and from high-quality parts, then these defects will be small, and they will need to be eliminated no more than once or twice a year (usually at the beginning of the season, as well as after serious cleaning). Low-quality rims will require more attention. they can form eights after each ride.

A flawless rim is a perfectly flat circle. It should be located exactly in the middle of the fork stays (and not relative to the hub flanges!).

Three types of defects can form on the rim:

“Eight”. when the rim is no longer flat, or when part of the rim does not coincide with the plane of rotation. Most often, it is the “eights” that are formed on the already assembled wheels

“Egg”. when the rim ceases to be a circle, that is, some part of it is closer to the center than others. The “egg” is less common than an eight, usually after unsuccessful landings.

“Umbrella”. when the rim does not fit exactly halfway between the fork stays. This type of defect is usually the result of improper wheel assembly.

Elimination of rim defects

Those wishing to learn how to fix rim defects on their own should take into account that wheel dressing is an operation that requires not so much skill as patience and perseverance. Because, in essence, there is nothing complicated in this matter. It is much more difficult to assemble a wheel completely, and for this task it is better for a novice cyclist to contact a workshop.

What it takes to learn how to drive a wheel?

  • Complete assembled wheel. You should not start practicing on an old, dead wheel with multiple defects. Although, on the one hand, I do not mind. But on the other hand, it is not always possible to straighten such a wheel to perfect condition. Also, eliminating one small figure 8 is easier than eliminating many overlapping eights and eggs, especially for a beginner bike mechanic. It is better to start learning on a new or almost new rim, until he has acquired dozens of eights.
  • A piece of chalk to mark a defective spot.
  • Spoke key.
  • Some free time.
  • It is very convenient to use a wheel straightener, but not necessary. Small eights on the wheel can be eliminated without removing it from the bike by turning the bike upside down. In this case, the correctness of the wheel can be controlled relative to the brake pads or fork blades.

Elimination of the G8

To eliminate the figure eight, you first need to find the place of the defect on the rim. To do this, spin the wheel and slowly bring a piece of chalk to the side of the rim. Mark with chalk the place where the rim is deformed (the chalk starts to touch the rim at this point). Thus, we determine where the figure eight is located, and in which direction the rim is deformed.

To eliminate the “figure eight”, you need to tighten the spokes on one side of the rim and loosen their tension on the other side. over, this must be done in concert. otherwise another defect may appear on the rim. an “egg”.

1) “Eight” is small, the defective spot was between two adjacent spokes. We tighten one knitting needle, for example, by 1/3 of a turn, and weaken the adjacent one also by 1/3 of a turn.

2) The “Eight” is small, the defective spot turned out to be opposite a spoke. We tighten this knitting needle, for example, by 1/4 turn, and weaken two adjacent ones by 1/8 turn.

3) The figure eight affects several adjacent spokes. The needles that are closer to the center of the defect are tightened or loosened more than those that are at the edges.

After that, spin the wheel again and see what has changed. If the figure eight has become larger than it was, then we return all the nipples of the spokes to their original position, and once again we figure out in which direction they should be turned. If it has decreased, but not completely, it means that we are on the right track, but we still need to tighten the nipples in the same direction.

Elimination of the “egg”

To eliminate the “egg”, you also first need to find the place of the defect on the rim. To do this, spin the wheel (with the tire removed) and slowly bring a piece of chalk to the rim (not from the side, but from the outside). Mark with chalk the place where the rim is deformed (the chalk starts to touch the rim in this place). Thus, we determine where the protruding part of the “egg” is located.

To eliminate the “egg”, the spokes must be tightened on both sides of the rim. over, this must be done in a coordinated manner. otherwise, a “eight” may appear on the rim. If we tighten one knitting needle by half a turn of the key, then two adjacent ones must be tightened by a quarter of a turn.

Usually for beginners, this process must be repeated several times before the “eight” or “egg” disappears. Then, as experience appears, small defects will disappear from the first or second attempt.

When eliminating eights, it is important to remember two features:

First, the spokes must not be overtightened (the rim or nipples could be damaged). If during the editing process one or several spokes are overtightened, loosen them together with the adjacent spokes and repeat the adjustment.

Secondly, the spokes must not be loosened (otherwise they will break when driving). If during the editing process one or more spokes are loosened, you need to tighten them together with the adjacent spokes, and then repeat the adjustment.

That’s all, as you can see the elimination of the figure eight and / or the egg on the bicycle wheel is not at all such a difficult matter, a little effort and patience and you can safely drive the wheels yourself, without resorting to mechanics.

We are not responsible for the rims damaged by you.

How to straighten a figure 8, an egg on a bicycle wheel.

During movement, a bicycle wheel perceives significant loads in all directions. both in the vertical (cyclist’s weight) and axial (maneuvers, turns, road irregularities), as well as in the transverse (acceleration and braking). over, the magnitudes of the efforts taken by the wheel are many times greater than the weight of the wheel itself.

Therefore, even if you ride very carefully, defects will still form on the rim. that is, violations of its geometric shape.

Correction of the “eight” wheel, “egg” and other bicycle ailments. instructions and advice

Editing the “eight” and “egg” on the wheels of a bicycle is a necessity almost every cyclist faces. Someone gives it to the service, someone rules the wheel himself, and does the right thing. self-editing of the eight is a guarantee of high quality work and saving money.

All that is required to correct the “eight” of the wheel and its other defects is a high-quality spoke, but you can limit yourself to a simple screwdriver, but it is much more difficult to work with it than a spoke. To simplify the work, you may also need a machine on which it will be easier to follow the changes in the wheel as a result of straightening, but you can do without it. just fix the wheel in the bicycle fork, and in fact, start doing the work itself.

How to fix a figure eight on a wheel

If one of the parts of the rim of your bike is offset to the right, then in the same area you should tighten the spokes on the left side and loosen slightly on the right. But do not overdo it. you should pull up one at a time, or half a turn clockwise and exactly the same number of knitting needles on the other side should be tightened. As a rule, eights appear on short sections of the rim and in the work on tightening and loosening the spokes. editing the “eight”, you have to use more than 1-4 spokes on each side of the wheel.

Note that if the rule for uniform tightening and loosening of the spokes is not observed, then an ellipse may be added to the figure eight on your wheel. And it is much more difficult to fix it. So, it works with the wheel in the loosen-tighten mode, and after each small turn we turn the wheel to the fork. if you have rim brakes, it’s even better, you can very accurately track the wheel runout and make it perfectly even as a result of your work.

We proceed to the second stage of editing

The fact is that even if visually it seems to you that the wheel is completely ready, you should not think that it is so. Editing the figure eight doesn’t end there. We put the wheel on the ground, resting it on the hub axle and pushing it with our hands from all sides. until it crackles. this will help the spokes to sink into their nests and show the realities of your affairs, in addition, if there is an opportunity and time, it is worth putting the wheel on the bike and half a day ride, and then, once again pass the wheel through your keen eye. If the figure eight appears again, then we do a neat operation to pull the needles for one more time.

In addition, you need to check whether the “umbrella” of the wheel is not gone, whether the edges of the wheel are still evenly removed from the fork of your bike’s fork legs. If all is well, then let’s move on, put the wheel on the bike and continue to enjoy riding it.

Editing an ellipse on a bicycle wheel

Editing an egg (ellipse). difficult for a beginner, but a solvable task. In order to straighten the ellipse on your bike wheel, you need to determine which section of the rim is farthest from the center of the wheel.

If you have a machine tool, then it will not be difficult to determine the remote area, otherwise we put the wheel bare from rubber in the bicycle fork, start twisting it and apply a ruler to the rim, where the ruler rises. there is the most remote area.

When straightening an ellipse on a bicycle wheel, the same principle applies as when straightening a figure eight. In order to accomplish this task, you will need to tighten the spokes in the distant section and loosen them in the section closest to the hub.

So it is necessary to do this along the entire perimeter of the wheel. as a rule, you cannot eliminate the ellipse with one small edit. you will have to sweat and spend more than half an hour of your time, and maybe more, depending on the neglect of the wheel.

Note that when editing an ellipse, it is necessary to loosen the spokes on the wheel evenly from both sides, otherwise you will have to edit the figure eight in the future. Also, on the ellipse, special attention should be paid to heavily weakened and, conversely, overly stretched knitting needles. we correct them first. Sometimes loosening just one spoke and easily correcting the subsequent figure eight on the wheel will completely help exhaust the problem.

Let’s add that while editing the ellipse, the number of turns with the spoke that you have to do is much more than during the editing of the figure eight.

At the conclusion of the work, we repeat the same instructions as during the editing of the figure eight on a bicycle wheel. we squeeze, roll, check.

Editing an umbrella on a bicycle wheel

If the wheel of your bike is completely displaced to one side and is not at an equal distance from different ends of the bike, then the work on fixing the “umbrella” has come.

Fixing the “umbrella” on the wheel is very simple. To do this, you will need to pull up the side of the wheel that is more distant from its edge by an equal amount of revolution, or, on the contrary, weaken it if the tension on the spokes is very high.

Wheel alignment with spokes. Editing the “eight” wheel, “egg” and other bicycle ailments. instructions and advice

The emergence of the figure eight is a problem that any cyclist has faced. over, eights on wheels will appear regularly, and as often as you actively use your bike.

Small eights, as a rule, do not create serious problems when driving, and you can safely ride for quite a long time without adjustment. Severe deviations make cycling unsafe and should be corrected. Wheel adjustment is a simple procedure, and you can do it yourself. How to fix a figure eight on a bicycle wheel and what tool you need for this we will consider in this article.

The reasons for the appearance of the eight

Wheel deformation is a natural and inevitable result of using a bicycle. When riding a bicycle, the wheels are subjected to different loads in the vertical plane. Even when the cyclist sits on the saddle, the wheels are immediately loaded. Add to this the unevenness of the surface, bumps, pits, if you prefer driving on a dirt road, this will also negatively affect the condition of the wheels.

Beginner cyclists are not yet able to properly distribute weight on the bike, this will also increase the load on the wheels. Cornering at speed, hard braking, all this contributes to the emergence of eights on the bike. The more often the bike is used, the faster it becomes necessary to adjust its wheels. Even if you ride very carefully, this problem cannot be avoided.

Riding style is not the only factor that determines how long your wheels last. The quality, material and manufacturing technology of the wheel rim can significantly reduce the likelihood of various defects. Inexpensive models, on the other hand, can have such defects when buying, and require repair much earlier.

The tool needed to fix the figure eight

  • It is imperative to have a spoke wrench, with which the figure eight is eliminated by changing the tension of the wheel spokes
  • A marker or crayon that can be used to mark the location of the figure eight on the wheel rim
  • It will greatly simplify the procedure for correcting the figure eight, and in general, a rather useful tool for the cyclist. a plastic tire for removing tires from the wheel

How to straighten a wheel on a bicycle

To do this, we will use a chalk or marker. On an inverted bicycle, spin the wheel, and slowly bring the chalk to it, thus getting in the place where the figure eight is. The chalk will leave serifs, along which the knitting needles are determined, the tension of which we will change. If you can’t keep the chalk on the weight, you can use additional devices. For example, on the fork of the front wheel, using adhesive tape, you can glue ear sticks and do the same operation as with chalk.

After determining the place where the figure eight appears, you can begin to correct it:

  • We start working with the spoke located in the center of the marked area. Depending on which side the figure eight manifests itself in, we take the knitting needle located on the side opposite to it. We tighten it with a spoke wrench at a distance of less than one turn. Weaken the two adjacent knitting needles on the side with which the figure eight was marked. The distance by which they need to be loosened should be less than the distance of pulling up the first spoke, for example, 2 times.
  • We continue to do the same actions with the rest of the knitting needles as with the previous ones, gradually decreasing the distance of pulling and loosening with the spoke wrench. Thus, it turns out that the central part of the figure eight, which is its focus, undergoes the greatest correction. We spin the wheel again, check the result. If it gets worse, we return the tension of the knitting needles to their original position, and perform the same actions, only we make the tension and loosening weaker than the first time.
  • Gradually, over several cycles of tightening-weakening, the figure eight will appear less and less significantly. To achieve the ideal spoke tension, you will have to go through these steps more than once, however, as mentioned at the beginning of the article, small eights will not lead to tangible problems while driving, so we recommend that people who do not suffer from perfectionism do not get carried away with this activity.

Eliminating a wheel defect known as an egg

The egg defect appears due to strong point overloads, usually caused by a failed landing. A wheel with such a defect loses its circular shape, taking on an elliptical shape that looks like an egg, hence its name.

The process of removing an egg on a wheel begins by identifying the affected area. The method of determining is similar to the process of determining the figure eight. The difference is that the chalk must be brought to the wheel rim from the side where the tire is. The tire must, of course, be removed. The tool used here is the same as for aligning a figure eight on a bicycle wheel.

The egg defect is eliminated according to the same principle as the figure eight, with the only difference that when correcting the egg, we will only tighten the knitting needles.

We start, as in the case of correcting the eight, from the central knitting needles in the identified area of ​​the egg, here we tighten more, gradually reducing the distance by which we turn the spoke key, as we approach the edges of the egg area.

Often, two defects can be present at the same time, therefore, having removed the egg, do not forget to eliminate the figure eight.

What to check after correcting wheel defects

Loose knitting needles must be tightened, overtightened loosened. Then you need to re-check the wheel for defects. If you still have overtightened knitting needles, the result suits you, but you are tired of adjusting, you can grind these knitting needles with a file.

When riding a bicycle, a bicycle wheel takes on various loads, and regardless of whether you drive carefully or not, the wheel deforms over time. wheel geometry is broken. Much depends, of course, on the quality of the rim, on a poor-quality rim, a figure eight can form after the very first rides on the bike, so when choosing, you should pay special attention to the quality of the rim and its assembly.

If you want to fix a rim defect. eight, and have no experience in this matter, then you need to know that this is not a very simple operation, since it requires a lot of patience and time.

Before starting to fix the figure eight on a bicycle, if there is no experience, I would recommend to practice on the old wheel. And so, in principle, there is nothing complicated in this, you need to follow the instructions correctly.

To fix a figure eight on a bicycle wheel, we need the following tools:

  • spoke key;
  • marker or piece of chalk;

You can also have a machine (more convenient) for the wheel. But if it is not there, then it is enough just to turn the bike upside down.

Steps to fix the figure eight

First of all, we need to find deformation points (figure eight) on the wheel on the rim, for this we take a marker or a piece of chalk, spin the wheel on an inverted bicycle and slowly bring the marker to the rim, the place where the figure eight will touch the marker and leave a trace on the rim, this is there will be a place where the eight is.

To eliminate the figure eight of the rim, a coordinated tightening and loosening of the spokes from the right sides is required, since if this is done incorrectly, new deformations may appear on the rim, consider further.

Consider a couple of options for eliminating the eight wheel on a bicycle, in various places on the rim.

The first option is how to remove the eight on the wheel. if there is a slight deformation of the rim, which is between two adjacent spokes. In this situation, we should tighten one spoke, for example, by 1/3 of a turn, and also loosen the adjacent spoke by the same 1/3 of a turn of the spoke key.

The second option can be if the figure eight is opposite any spoke. In this case, we need to tighten this spoke, for example, by 1/4 of a turn, while it is necessary to loosen the adjacent knitting needles by 1/8 of a turn.

We will also consider the option of how to straighten the figure eight on the wheel. if the wheel eight has affected several adjacent spokes. With this deformation, it is necessary to tighten or loosen the needles that are closer to the center of the figure eight than those that are at the edges.

Correcting the figure eight on the wheel according to the video instructions

After each step taken, it is necessary to spin the wheel and look at the wheel, if the wheel became even, then everything was done correctly, but if the figure eight increased, then it is necessary to bring everything to its original position and figure out what was done wrong in a new way. If the figure eight has become smaller, then you can continue to tighten and loosen the knitting needles in the same spirit, you are doing everything right.

Good luck and less breakdowns.

One of the important components of a bicycle is a spoke wheel, which is installed on almost all models of this two-wheeled mode of transport. But if during the ride you saw how it encircles the “eight”, then you should not be upset. Every cyclist faces this problem.

How to straighten the figure eight on a bicycle wheel in such a situation? You can fix this problem yourself without spending a lot of money. At the same time, a slight curvature will not present serious problems when driving. Only a significant defect will make the trip dangerous and it must be eliminated immediately so as not to be injured and not to carry out a more difficult.

Repair of the “eight” wheel of a bicycle is a common problem that requires surgical intervention. The fact is that the front and in the upright position experience all sorts of loads, even when a person just sits down on the saddle. And driving on a highway with potholes and pits exacerbates this impact.

A person without experience cannot competently distribute body weight, cannot turn correctly, brake smoothly and not jump. All these actions lead to the appearance of defects due to which the question arises: “how to remove the figure eight on a bicycle wheel?”

Important! Whatever the reason, when this defect appears, it must be urgently eliminated!

Tools for repair

Eliminating the figure eight on the wheel will require the use of the following tools:

How to identify curvature?

Before getting down to work and starting to fix the G8, you need to determine the type of malfunction and its location. Work execution algorithm:

Defect elimination

So we came up to answer the question: “how to fix the figure eight on a bicycle wheel?” But before proceeding with the restoration work, keep in mind that there are several ways by which the “eight” is corrected on a bicycle.

Power

To align the figure eight using this method, remove the wheel from the frame.

Good to know! No need to remove tire and camera.

Take the wheel from both ends so that the side with the defect is facing you. Now we put the knee on the most convex part and press hard from ourselves. This work is carried out “on weight”.

You can also do all of the above with the wheel while it is on the floor. To do this, put it with the defective side up and press on the central part of the curvature, in parallel with this, pulling the sides of the wheel towards you. In this situation, it is better to use the help of another person to firmly fix the rim to the floor.

After the curvature has been corrected, the wheel is placed on the frame and the fault is re-troubleshooting by rotating the wheel. This method of eliminating the defect is not very effective, but it will help on the road. when the “eight” on the bike was formed suddenly when hitting a large obstacle.

Spoke adjustment

First, check the overall spoke tension. Often the figure eight on a bicycle wheel appears due to the fact that they are loose: the spokes, if you slide your fingers over them, “walk” like the strings of a guitar. Then just tighten them around the entire diameter of the wheel one turn. If everything is fine with tension, you will need to find the defective area with a crayon and start correcting the bulge.

You need to start straightening from the center spoke. which is located in the mark zone. It turns in the opposite direction to the bulge. As a result of such actions, the spokes located on the sides of it are weakened.

Seven spokes

  • Central tightens 1/2 turn.
  • The side needles from it are loosened by 1/4 turn.
  • The following needles are tightened 1/8 of a turn.
  • The outer needles are loosened by 1/8 of a turn.

Please note that only painstaking and gradual work in several stages will help to repair the “eight” on a bicycle and restore it for a convenient and comfortable ride.

Workshop cost

If you decide to go to a workshop, where a specialist will carry out work to eliminate the defect for you, you need to know how much it costs to remove the figure eight on a bicycle wheel. On average, depending on the degree of curvature.

At the same time, the service does not always immediately know how much it costs to straighten the figure eight on a bicycle wheel, in contrast to situations where they can immediately tell you what to do, when. And all because because different situations differ in the complexity of the work. The final price will be known only at the end of the problem diagnosis.

The video will tell you how to remove the “eight” on a bicycle wheel.

Among all the components of a bicycle, the most conservative is the spoke wheel. This type of wheel fits most bikes and is simple in design: a center hub, rim and spokes that connect the rim to the pivot. During the operation of the bicycle, the wheel is subject to static, dynamic and shock loads, as a result of which changes in its shape can often occur.

Deformation of the “eight” type. what is it

Bicycle wheel curvature is associated with a misconfiguration of the rim. In other words, the wheel is no longer round. A common variant is the so-called figure eight, when a deviation of part (or several parts) of the rim from the plane of rotation is observed. When rotated, these regions describe trajectories in the form of eights around the central axis of rotation. When riding a bicycle, this defect is expressed in beating or wobbling on the go.

You can ride with eights, but it is unlikely to be a pleasure. In addition, deformed wheels are less resistant to stress, which will lead to further distortion and complete unsuitability of the rim. Can I fix the figure eight on a bicycle wheel myself? Yes, and it’s not difficult at all. How to do this in the article.

Determination of curvature on wheels

So, there is a suspicion of the occurrence of wheel deformation, and it remains to determine exactly where it was formed. Turn the bike upside down and fix it clearly.

The first identification method is visual, which allows finding the location of large and medium defects. The wheels must be spun strongly, since at low speeds the eights, even the coarsest ones, show poorly. The rear wheel can generally be pedaled. Curved sections move away from the plane of rotation to the side. At maximum deflection, the wheels must be quickly grasped in this place. It is not easy to do this at high speeds, and the hand can slip off, so it is better to resort to the following method.

The second method. contact, consists in marking the damaged area. As an indicator, you can take a marker, or rather a regular crayon. Spin the wheel and slowly bring the chalk to the rim. The first thing he does is strike a figure eight along the edge of the bulge. After the “top” is determined, the wheel must be spinned even more and continue to bring the chalk closer. This defines the entire area of ​​curvature. As soon as the chalk “runs” over the entire rim, the test can be considered complete. The focus of the figure eight will clearly stand out with a bold line against the background of a pale stripe along the entire circumference.

This is how the curvature of the rim is recorded.

Elimination of defects in a bicycle wheel

When the curvature of the wheel is found, it’s time to start straightening it. Every owner of a two-wheeled vehicle can do it with their own hands, especially since such problems can arise with enviable regularity. There are two ways to eliminate the figure eight on your own:

  • Strength straightening, or “knee” as cyclists say.
  • Wheel spokes tightening and loosening method.

Power straightening

To remove the bend in this way, you will need to remove the wheel from the frame. In this case, you do not need to remove the tire with the camera. Turn the bulge towards us and grab the rim and tire on both sides. With medium deformations, the optimal grip of the wheel is position “10” and “2”, that is, 60 degrees to both sides of the eight. We put the knee to the most convex area and press hard from ourselves.

Which wheel alignment will best allow the rim to align? If there is enough strength in the leg, then you can press on weight. An alternative is to place the wheel vertically with the defective area up. The help of a partner is needed here. He must firmly press the wheel to the floor. After straightening, the wheel is put on the frame and checked again by rotating.

This method cannot be called effective for several reasons:

  • It is impossible to bend small bends.
  • The rim may bend to the other side.
  • Uncomfortable.
  • Low accuracy.
  • Not every rim can be so easily subjected to simple force.

This method works relatively well somewhere on the road, when the figure eight was formed suddenly due to a swoop on a large obstacle and it must be urgently straightened in order to reach the destination.

Wheel spoke adjustment

Attention! The spoke tension should only be changed with a spoke wrench, and never with pliers or adjustable wrenches.!

It will take patience to align a figure eight on a bicycle wheel, especially for first-timers. Tires must be completely removed.

Check the tension of all spokes first. Often times, the rim is bent due to their overall weakening. It is easy to check this: when the spokes are clearly dangling and “obey” the fingers like strings on a guitar, then they need to be tightened by about 1 turn over the entire wheel. If such a problem is not observed, then nothing needs to be touched: this way you can only aggravate the eight.

We mark the defective area and proceed to the “central” spoke. the one located at the bulge. The spoke is turned in the opposite direction to the bulge. The spokes on the sides of it are loosened. With a figure eight for three needles, the straightening scheme is as follows:

  • Tightening the central quarter turn key.
  • Weakening of the outer needles by an eighth of a turn: the weakening force is half the tension in the center.

Eliminating the little eight

With an eight for 7 spokes, wheel repair is done as follows:

  • The center is pulled half a turn.
  • Weaken two spokes (second and third) on the sides by ¼ turn of the key.
  • 1/8 tightens the fourth and fifth needles.
  • The sixth and seventh (outermost) needles are loosened by 1/8 of a turn.

Straightening the Big Eight

The alternation of pulling and stretching is carried out in such a way that the outer needles on the figure eight are loosened. To check the result, the wheel is hung on the bike and tested for residual curvature. If the figure eight is bent in the opposite direction, you should remove all tension and increase the tightening torque on the loose knitting needles and repeat the procedure again, but already with less tightening and loosening forces.

Despite the fact that you have to tinker a lot, you can achieve the ideal result. straightening the wheel to an even circle. And if for the first time the work may take too long, then with the subsequent occurrence of the eight, the repair will go much faster. Now, when a defect appears on the wheel, you can not put the bike aside, but quickly adjust the spokes yourself and resume trips.

Wheel bending is an unpleasant thing

If your wheel is bent and you don’t know how to fix it, you are in the right place. I have already come across this problem and will tell you simply. repair is possible. everything is quite simple. over, I will say that the problem that you are faced with will most likely arise at an enviable frequency if you love your bike and ride it several times a week. Therefore, it is worth learning this once, so that in the future you can remove the breakdown yourself every time it occurs.

How to tell if your wheel is OK. Simply place the bike upside down on the saddle and on the handlebars, wheels up. Spin the problematic wheel, as you think, (spin it in the sense of rotating it around its axis) and check it “by eye” first. If everything is in order with the wheel, then it will rotate around the axis absolutely evenly. If there is a figure eight, then it should be visible to the naked eye or, more often than not, something like the beating of a wheel in a certain place. It is necessary to look at the wheel in profile and face, since the bending of the wheel can occur in different directions.

Types of bends that are possible in principle: How defects can form and why

There is a widespread belief that a wheel can change its shape if you do not ride carefully, when driving over bumps or during unsuccessful jumps. This is all true. That is, all this, of course, affects the rapid wear. But that’s not the only reason a wheel can break. When the cyclist gets on the bike, the wheels are already being loaded in the vertical direction. Further, when braking at speeds, the wheels can deform, forming eights. When maneuvering (cornering) in any direction and hard braking. In general, I think you can not explain what sloppy driving is, you yourself understand everything perfectly. So caring for your bike can put off the problem, but over time you will come back to it anyway. Even if you ride very carefully on a good road, such is the specificity of a bicycle.

Everything, of course, still depends to a large extent on the wheel rim itself, on its physical characteristics. Therefore, when buying a bicycle, you need to pay the seller’s attention to such things, wondering how long the wheels can last, how they react to the deformations described above. So on cheap bicycles, the rims are correspondingly less strong. And various bends (egg and eights) of wheels can form much earlier than on their more expensive and high-quality counterparts.

In general, how the problem can arise, I think you already understood. So let’s get straight to how to solve the problem and align your wheel.

What tools we may need to eliminate defects. So, to fix your wheel you may need:

  • crayon or something that can draw on the rim of the wheel (water marker)
  • universal plastic assemblies for dismantling bicycle tires.

We need the spoke key. I must say right away that you won’t have to pull up much. You will gradually tighten the knitting needles and check the results immediately.

General algorithm for eliminating problems with a deformed wheel

The general algorithm is as follows. we determine in which specific place the figure eight begins and where it ends (we select the lesion focus). The next step is to find the center needle in the figure eight and work with it. If our figure eight falls to the left side, select the spoke on the opposite side and pull it up a distance of less than one turn of the spoke key. Then we take two adjacent knitting needles. these will be knitting needles already on the opposite side of the previous knitting needle. weaken them by the number of revolutions a little less (for example, 2 times less) than we tightened the previous knitting needle. And so on until fully straightened. That is, the next two knitting needles (they will be placed on the opposite side) are already tightening even weaker than the very first knitting needle. As you move away from the central spoke (lesion focus), the number of revolutions, respectively, will also decrease gradually.

If the figure eight is small by three needles.

So, again, how do you fix an eight on a bike? To fix the wheel, we select a section where there is an eight, and along the length of this entire section we loosen and tighten the spokes going one after the other. We loosen the spokes on one side of the wheel, and tighten them on the other. When the required operations have been completed with all the spokes, we rotate the wheel again and see the correct movement of the wheel around the axis. If it becomes worse, return the knitting needles to their previous place and make the tightening-weakening less. Thus, the skew in one direction leading to the figure eight will gradually level out. To perfectly align the figure eight, you will have to patiently and painstakingly perform all of the above actions slowly (i.e. we twist a little).

Eight larger. to be treated as well as small.

The wheel is flattened by an egg, the straightening algorithm is slightly different. We only pull up the right side.

The egg-on-wheel defect occurs most often due to unsuccessful landings. It is flattened vertically. Quite often, an egg in combination with an eight is found on the wheel. So having corrected one, do not forget to correct the other. Unlike the figure eight, an egg-type defect is treated by pulling the knitting needles on both sides. We also identify the lesion and gradually, as shown in the picture above, we need to straighten the egg by pulling the knitting needles. It will be said below, but it is necessary to ensure that all the needles are not overtightened or, on the contrary, too loose.

How to straighten a wheel in practice and how to determine exactly where the eight of a bicycle wheel goes

How to determine exactly where the eight passes. Masters who have gotten their hands on in this matter can fix the problem without improvised means (crayons and other things). You will have to edit the wheel first using chalk. We spin (rotate) the wheel and gradually bring the chalk to the rim of the wheel rotating in the axle. In those places where there is an eight, the chalk will touch the rim and scribble serifs on it. So you define an eight for yourself.

I saw another great option on how to straighten the figure eight on a bicycle wheel in one video. We take ear sticks. On both sides of the wheel we have front fork stays. We attach ear sticks to these feathers on scotch tape from both sides and, just like with a crayon, rotating the wheel, gradually bring the ear sticks to the wheel rim and the places where they begin to clearly touch the rim. mark with chalk. Quite a convenient option, since it can be quite problematic to hold the chalk on the weight. If your wheel is flattened like an egg, that is, it has lost its perfectly round shape, we do everything the same as for the figure eight, only we bring the chalk from the outside of the rim. where the tire with the camera should be.

As you can see from the above, the elimination of the figure eight on a bicycle is not a very difficult process, and what is most pleasant is that it is accessible to everyone. The only thing I want to add is that when you’ve done all the work of aligning the figure eight on the bike, be sure to check all the other spokes. What shouldn’t be? The needles should not be loose or overtightened. Loose spokes can break, so carefully tighten them and repeat the wheel adjustment again. If the spokes are too tight, they can pierce the pin or wheel rim. Craftsmen advise if you have tuned the wheel and everything suits you, but some spokes stick out from the wheel rim, you can sharpen them with a file. so as not to pierce the camera.

As a result, I would like to say that it is better to learn to do all this yourself once. than to go to the workshop every time. Personally, I remember the workshops as would-be masters who do not have time to serve everyone, so they do everything in haste. And you are the owner of the bike and you can do everything unhurriedly, unhurriedly, literally and accurately. So go ahead and buy spoke wrenches and fix your bike wheels!
