How to align a figure 8 on a bicycle wheel with spokes

Fundamental rules

So, in order to know exactly how to fix eights on bicycle wheels, you need to remember a few rules.

First, overtightening the wheel spokes can damage the rim. If in the process of straightening one or more of the spokes turn out to be overtightened, it is necessary to loosen them and the adjacent spokes, and then repeat the adjustment again.

Secondly, the spokes can break during the ride if they are very weak. If in the process of straightening one or more spokes of the wheel turned out to be loosened, it is necessary to tighten them, then repeat the adjustment again.

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 operation 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.

Elimination methods

Even if there is no experience in such matters, acting carefully and following the rules, you can fix the “eight” on the wheels of a bicycle with your own hands at home. Before starting work, you need to prepare tools:

  • key for knitting needles;
  • chalk or marker for marking defects;
  • plastic assemblies for mounting and dismounting tires.

There are two methods of dressing a bicycle wheel: power and spoke tightening. Each of them has its own strengths and weaknesses.

Causes and prevention

The appearance of deformation is possible due to long-term use. The main reasons for the emergence of the G8 are:

  • when the vehicle is moving, a vertically directed load acts on the structure, which depends on the weight of the cyclist;
  • careless, careless driving, falls, hitting bumps, falling into holes will affect the symmetry and lead to deformation;
  • a high-quality rim several times reduces the likelihood of the appearance of a “eight”, in budget models already at the time of purchase there may be a defect;
  • regular active driving, hard braking, tearing accelerations, sharp turns at a strong angle contribute to the curvature of the rim.

Rim curvature isn’t just caused by a dashing ride. Even with proper use of the bike, deformations inevitably appear over time.

The best professional advice for prevention is to regularly inspect the rim, spokes, center hub, tires for faults or wear. It is necessary to timely replace components and parts of the bike. This will avoid unnecessary problems and expensive repairs.

Careless driving, falls, collisions on bumps Poor-quality rim Regular active driving, harsh braking

Eight on a bicycle wheel. fix it yourself

The spoke wheel is one of the most classic elements of your bike, as it is found on most modern bicycles. The configuration of such a wheel includes:

In the course of long-term operation, the wheel is subjected to significant stress and can be deformed over time. Therefore, every cyclist should be able to fix simple problems on his own.

Wheel deformation is called “figure eight” in the event that part of the rim deviates from the plane of rotation. With such a malfunction, you can ride a bike, but there will be no pleasure from such a walk. over, over time, the figure eight will lead to the fact that the rim will completely become unusable and will need to be replaced with a new one. Therefore, it is better not to delay and fix the problem immediately after its identification.

How to correctly identify the presence of an eight?

If you begin to suspect that the wheel is deformed, the first step is to find the place where the rim is curved. This can be done in two ways:

In the first case, you simply spin the wheel vigorously and define a curved section. It will constantly move away from the plane of rotation. At this point, you need to grab the wheel with your hand and mark the deformed area with a marker. Preferring the contact method, you take a marker and rotate the wheel, drag it along the rim. The marker should make a full circle and after that you will clearly see the place of deformation.

how to identify the eight

After you have identified the area of ​​deformation, the only thing left is to eliminate the figure eight. You can easily do it yourself without asking for help from specialists. There are two main ways to eliminate the figure eight:

Experienced cyclists do not really trust this method and resort to it in the event that the deformation of the wheel caught them suddenly on the road and you need to fix the malfunction in order to get to the destination. In order to correct the figure eight by force, it is necessary to remove the wheel from the frame, turn the deformed section towards you and firmly grab the rim and tire on both sides. Press the deformation area with your knee and press away from you with maximum force. It is difficult to call this method effective due to the following reasons:

  • You will not be able to eliminate small bumps
  • There is a risk of bending the rim the other way
  • Eliminating the figure eight by this method is very inconvenient.
  • Some rims are simply not subject to human force

How To True A Wheel

elimination of the figure eight by pulling the knitting needles

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.

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.

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 line up 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 “obeying” 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 turn of the spoke is carried out in the direction opposite to the direction of 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.

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 (extreme) needles are loosened by 1/8 of a turn.

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 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 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.

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 you 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.

What position of the wheel 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 section up. This is where the help of a partner is needed. He must firmly press the wheel to the floor. After straightening, the wheel is put on the frame and checked again by the rotation method.

This method cannot be called effective for several reasons:

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

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.

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.

Deformation of the “eight” type. what is it

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

Riding with eights is possible, 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 a 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 detection method is visual, which allows you to find 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.

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.

Eight fix features

After determining the area where there is deformation, you can independently perform repairs without the help of specialists. To do this, you should decide on the method of performing the work. Distinguish between the power method and the method of tightening. The strength method is not very popular with experienced riders. It is used mainly only when a breakdown has caught a cyclist on the way. In this case, you will need to remove the wheel from the frame, turn it towards yourself in a section where there is a curvature, and then grab the rim and tire of the bicycle from both sides as tightly as possible. Next, you need to press the area where the curvature is marked with the help of the knee, and push yourself with effort. This method is rather difficult to call effective, since you can get rid of only small bulges, and there is a risk of bending the rim in the other direction.

The most effective is the method of tightening the needles. Riders should have a spoke wrench available. It is not uncommon for the wire to become bent due to the weakening of the spokes. For this reason, if you tighten them one turn at a time, you can align the wheel. You should start from the center. It is also important to take into account that the knitting needles should only be turned in the direction opposite to the bulge itself. As a result, you will be able to fix the breakdown in a fairly short time and as accurately as possible, and then continue to enjoy riding your mountain bike.

How to fix a figure eight on a wheel

The spoked wheel is the most classic element of any bike, as it is found in the majority of models. In the configuration of such an element, there is a center hub, rim and spokes. During a long operating period, the wheel is subjected to significant loads. For this reason, after a certain time, deformation is not excluded. Cycling enthusiasts who love long walks should have a bike tool kit with them that can be used to troubleshoot the problem. However, it is also important to be able to eliminate them on your own. In this article, we will talk specifically about how to fix a figure eight on a wheel.

In what ways is the figure eight on the wheel determined?

If you have any suspicions about the deformation of the wheel, initially you should find the area where the rim is curved. This procedure can be performed both visually and by contact. When choosing the first option, it is enough to spin the wheel intensively, after which the curvature will be visible. At this time, you will need to take the wheel with your hand, and mark the deformed area in some way, for example, with a marker. If you prefer the contact method, you will need to run the marker along the rim while the wheel is spinning. It is important that the marker makes a full circle, since only after that it will be possible to see the place where there is deformation.

Fixing a figure eight on a bicycle wheel

Before starting the repair of the bike, you should initially figure out which deformation is called the figure eight. This concept means the deviation of a part of the rim from the plane of rotation. In this case, of course, you can ride a vehicle, but you are unlikely to enjoy it. In addition, the presence of a figure eight is the reason for the rim to become extremely unusable, and it will no longer be suitable for further operation. It is not worth delaying the elimination of the problem, it is better to start the restoration immediately after identifying a breakdown.

You should not postpone the restoration of your bike, as as a result, the repair can not only take longer, but also cost much more due to the need to purchase new parts and elements. Therefore, immediately after detecting a malfunction, it is advisable to proceed with its elimination.

The force method, of course, is not prohibited, and can be useful in certain situations. However, there are certain risks of causing even more damage. Therefore, we still recommend using, if possible, mainly the technique of tightening the knitting needles. Do not forget that only when riding a bike in good condition can you get real pleasure.
