How to pull the spokes evenly on a bike

Fitting the spokes of a bicycle wheel

Adjusting the spokes on a bicycle is carried out in several stages. All work can be done at home if the necessary tools are available.

How to correctly install and / or tighten the spokes on a bicycle

No matter how the statement of bicycle masters sounds, but the problem with installing / replacing and tightening the spokes on a bicycle wheel is the most common problem when customers contact service points. But for experienced cyclists, such statistics are not at all surprising. thin spokes have a great influence on the dynamics of the bike, and the quality of riding, and on the safety of the bike.

In order to tighten the spokes, a special tool is used. a spoke wrench. The bicycle parts under consideration are installed and tightened by twisting the nipple, while the main point in the process is the uniform tension of all the spokes. this serves as a guarantee of even distribution of the load on the wheel rim.

In general, bicycle wheel lacing can be done in different ways, but the most popular and reliable are radial and cross. At home, experienced cyclists often make a three-cross spoke setting, that is, the spokes in the wheel intersect three times with each other.

Types of spokes for bicycles

Bicycle spokes are divided into three large groups, which differ in their technical characteristics:

  • by the thickness (caliber) of the knitting needles. this rod can have a thickness of 1.5 mm, 1.6 mm, 1.8 mm, 2 mm and 2.34 mm;
  • by the type of head. bent spokes, used on assembled wheels, and straight spokes, installed on branded wheelsets;
  • by design type. cylindrical with butted and flat (aerospitz).

Note: Butting is a reduction in the thickness of the spoke in the middle (central) part of it, although towards the edges the spoke “acquires” its declared thickness. Thus, manufacturers reduce the weight of the spoke, while not at all reducing its quality and functionality.

The first step is determining the length of the bike parts

If you have to adjust the spokes on the front wheel of the bicycle, then you can not even deal with determining the length of the parts. it is believed that it is the front wheel that is structurally simple, the length of all spokes is absolutely the same.

As for the rear bicycle wheel, things are a little more complicated. The fact is that in this wheel the spokes are set of different lengths, since it is necessary to observe the difference in inclination.

Note: experts do not recommend that you independently determine the length of the spokes. For this, there are special calculators on the sites that allow you to get the necessary calculations online.

Pulling and Pushing Spokes

How to tighten the spokes on a bicycle

The structural part of a bicycle wheel, which, according to its technical characteristics, is the rod connecting the hub and the rim, is called a spoke. It is the spoke that is designed to facilitate the design of the wheel, while not reducing its strength.

The spokes can be installed and tightened with your own hands. for this it is absolutely not necessary to have any specific knowledge, which excludes contacting the bicycle service centers. For absolute beginners in this business, it is enough just to get acquainted with brief information about what types of spokes can be installed on a bicycle and how to change / tighten them correctly.

HOW TO TRUE YOUR WHEEL! VERY IN-DEPTH

The second step is editing

To carry it out, you need some tool. a spoke wrench and a screwdriver. And you need to do the work in strict accordance with the step-by-step instructions:

  • Lubricate the connection points with the nipples on the wheel parts and the threaded part of the spokes.
  • If there is a recessed entrance on the flange only on one side, then the spokes must be installed from the opposite side.
  • Nine spokes are installed in the flange. this is done through one hole, that is, there should be a free “niche” between the spokes.
  • If the work is carried out with the rear wheel, then the spokes are mounted to the right of the hub.
  • We find the same located on the right side of the valve inlet on the rim, place a spoke in it and twist the nipple, making 2 turns.
  • From the first installed spoke, we count 4 inputs clockwise and mount the second spoke and also twist the nipple with two turns.
    Note:the sleeve with the threaded part must be located to the one who carries out the work.
  • In the process of installing the spokes, you need to check the correct operation. the spokes should connect the rim to the right with the hub flange, and there should be three free entrances between the installed spokes.

The subsequent spokes are installed according to the same principle, and then the wheel must be turned towards you with the opposite side and the spokes must be installed in the order indicated above. Installation is started with the key spoke, which is located to the left of the valve inlet.

Note: when all the spokes are installed, you need to align the nipples to the same twist depth. That is why it is recommended to make 2 turns in each case so as not to make a mistake, and it will be easier to regulate them at the end of the work.

Step Three. Tensioning the Spokes

This step is considered final and easy to complete. You just need to make sure that the nipples are screwed in the same number of turns. If the needles are short, then this can be determined by the number of visible “steps” of the thread in the nipples

After all the steps are completed, you need to install the wheel with the dialed spokes on a special machine or any other device (you can use a bicycle for this). It is in this position that all the irregularities will be visible. the skew of the wheel in any direction can be corrected by adjusting the twist of the nipples. In most cases, half a turn is sufficient to align the wheel. Please note that such a check must be carried out twice. when the wheel is horizontal and when it is vertical.

How to tighten the spokes on a bicycle

Radial runout (ellipse, egg)

To edit the eight, popularly called the “egg” is somewhat more difficult.

First of all, remove the tire to make sure the curve is the rim and not the rubber, as is often the case.

On an upside down bike, spin the wheel, and with an object on top, mark with chalk the area of ​​the rim that lifts this object. Try to localize the very center, the main spoke.

Now you have to follow three directions at the same time: start to loosen the tension, starting with the center spoke, pull the adjacent two spokes exactly the same number of revolutions so that there is no figure eight, and pull the spokes at the opposite end of the wheel to prevent an egg from appearing elsewhere.

It seems very difficult (it is) and only experience is needed here. You need to understand that you will not wind up anything particularly terrible, and you can always start all over again, loosening, and then evenly pulling all the knitting needles.

Just like in the case of the figure eight. after straightening the eggs, you need to “seat” the knitting needles, pressing on them with all your weight.

Editing “Umbrella

There is also such a concept. “umbrella”. Look, most likely your wheel rim is not perfectly in the middle of the hub, but offset to one side. This is called an “umbrella”. The values ​​of this displacement depend on the type of brakes and the design of the frame.

You need to edit the “umbrella” in the same way as the eights. pull the knitting needles on one side, and loosen the knitting needles on the other side by the same force. Only here, in contrast to the editing of eights, the effort should not fade, but remain even along the entire circumference.

Determination of length

The first step is to determine the length of your bicycle spoke. On standard front wheels, all spokes are of the same length. If you have to adjust these parts on the rear wheel, you must first set the length of each spoke.

The easiest and most affordable way to measure knitting needles at home is to use a special online calculator. All that is needed for this is to specify the type of wheels (front, rear, with or without a rotor) and then enter the required parameters. the width of the hub, the diameter of the left and right flange, the inner diameter of the rim and its wall thickness, the number of spokes in the wheel, as well as number of crosshairs on the right and left sides.

Is it possible to make a spoke wrench with your own hands?

It is impossible to imagine a cycling enthusiast’s toolbox without a spoke wrench. No one is immune from wheel impact, often there is a need to fix a spare part on the road in order to prevent friction of the rim on the frame or brake pads.

It is recommended to repair the consequences of an impact at home, preferably using a machine, but preliminary work can be done right on the road.

What is required

Before tightening the spokes on a bicycle at home, you need to prepare the following tools:

  • Spoke key. which must be selected in accordance with the size of the nipples and the diameter of the spokes;
  • Special machine for aligning and straightening spokes. If this tool is not available, you can simply set the bike up.
  • Zonometer. a tool for aligning the wheel rim with respect to the hub.
  • Bicycle spoke tension meter.

What are the knitting needles?

The knitting needles can be divided into several groups, depending on the following parameters:

  • by caliber (thickness): 1.5 mm, 1.6 mm, 1.8 mm, as well as 2.0 mm and 2.34 mm
  • by the type of head: straight (traditionally for a branded wheelset) and curved (for an assembled wheel)
  • by design: cylindrical with butted and constant thickness, as well as aerospitz (flat). Butting means the reduction of a spoke in its middle part, where it receives minimal loads, in contrast to the ends of a spare part, which allows to reduce the weight of the spokes.

A bicycle without spokes and a central axle in wheels

Is a bicycle without spokes in wheels possible? Yes, recent developments offer rover models that are not designed to use the familiar wheel with a tire, axle, rim and spokes. They are surprising not only in that they actually challenge the statement about putting sticks in wheels and that the wheel cannot be invented. It turns out that we owe the “discovery” of such an element without using the central axis to an Italian named Franco Sbarro, and today you can see prototypes and working models of almost any type of transport using such wheels, including rovers.

For bikes, the spokeless wheel design is a very large bearing, while the inner part of the wheel remains stationary as it moves. In theory, such a wheel model should be superior to a conventional wheel due to its lightness, lower center of gravity and increased stability. And what is the amazing appearance of such a detail! However, such wheels are very expensive and technologically complex to manufacture. In addition, problems with protection from dirt, fastening of parts and the ability to equip with brakes need to be addressed. Also, while there are difficulties when passing bends.

Silver Zhaben’s electric bike without spokes

Nevertheless, the idea of ​​a bicycle without spokes appealed to Sylvain Gerbert, a Frenchman, who in 2013 presented an interesting model of an electric bike equipped with just such wheels. Called Synapse, the concept features electric motor-driven power transmission to the rims and an unusual frame-to-wheel connection. Of course, questions arise as to whether the wheels are securely fastened and whether it is possible to overcome road obstacles on such a rover, but wheels without spokes have already begun.

How to install and tighten spokes on a bicycle: guidelines and tips

Surprisingly enough, the spokes are called one of the most frequently repaired rover parts. Indeed, these subtle details largely determine the dynamics of the bike, the quality and safety of riding.

To tighten the spokes, you need a tool called a spoke wrench. By twisting the nipple, these parts are installed and tightened. In this case, the main point is the uniformity of the tension of the spokes, which guarantees the correct distribution of the load.

The spacing of the wheel can be different, but the key ones are cross and radial. The most common and convenient is called a three-cross: this means a triple intersection of each of the parts.

Spoke adjustment on a bicycle can be divided into several steps, including preparing, installing parts or padding the wheel, and tensioning the spokes. All stages can be done at home with patience, skills and free time, or you can entrust the rover to the master.

The first step is to determine the length of the bike parts. The front wheel, which is considered more technically simple, is described as having the same length of parts on both sides. As for the rear, it is distinguished by different lengths due to the difference in the inclination of the bicycle spokes. This is due to the requirements for wheel alignment and the presence of speeds. To calculate the length of the parts you are looking for, online calculators are often used, where it is enough to enter data on the dimensions of other parts and get the result.

The second, mounting, step requires a rim, spokes, bushing, oil, a spoke wrench and a screwdriver. The sequence of correct actions is as follows:

  • Thoroughly lubricate the nipple connection points on the wheel parts and the threaded part of the spare parts, which guarantees a good tension of the spokes.
  • If there are deepened entrances on the flange only from one side, you need to install the spokes from the side opposite to the grooves.
  • Flange accepts nine parts with one unoccupied entry between each.
  • On the rear wheel, spare parts are placed to the right of the hub.
  • On the rim, among the entrances located on the right hand, you need to find the one located on the right side of the valve entrance and place the first spoke in it, then screw the nipple by making two turns.
  • Starting from the first spoke, four inputs are counted clockwise, the second spoke is installed and the nipple is screwed in the same way. The threaded part of the sleeve is turned towards you.
  • The installation progress must be monitored: if everything goes right, then the spokes connect the rim on the right with the hub flange, also on the right, while there are three unoccupied holes between the spare parts.
  • The next seven parts are fixed in the same way, by installing in every fourth rim hole.
  • Now you need to turn the wheel on the opposite side and install 9 spokes in turn, mounting them in the flange located on the left hand. In this case, you need to start with the key spoke, which is located to the left of the valve inlet. After putting it on, install the remaining eight knitting needles in the same way as on the previous side.
  • Inspection of the wheel should show that pairs of unoccupied entries alternate with pairs of nipple entries along the entire length of the rim. To secure the nipples, turn them two times.
  • The stage of installing tensioning parts, whose heads are located on the back of the flange. One of the spokes is threaded into the flange hole, and the bicycle hub is twisted in such a way that the direction of the already mounted parts is close to the tangent to the flanges.
  • When installing the first tensioning parts, pay attention to their installation in the rim holes that are closer to the required flange. The remaining spare parts with a tension element are recruited in the same way. If they do not reach the nipple inputs, you need to loosen the nipples of the already inserted spokes one turn.
  • When the installation of all the spokes is complete, it is necessary to screw the nipples to the same depth.
pull, spokes, evenly, bike

Finally, the third step involves the tension of the spokes, which must be uniform, for which the nipples are twisted at the same level. If the parts are short, then the same number of threads should be visible after tightening. For long spare parts, the outgoing end is aligned with the slot of the nipples.

Finally, it is necessary to put the desired wheel on a special machine or, in the absence of one, on the rover itself: this is how you can identify the irregularities of the spare part. Pay attention to whether irregularities are conspicuous. With the horizontal nature of the unevenness, if the rim is shifted to the right side into four parts: two of them look at the left, and two. at the right flange, the left nipples are twisted ¼ turn and a similar, ¼ turn, the nipples are weakened from the right side. If this method did not help get rid of the unevenness, then you need to find the most uneven place on the left and tighten it.

To correct vertical irregularities, it is necessary to find the place of the rim as far from the hub as possible. This is required to maximize the tension of the part in that place, which will improve the parameters of wheel rigidity and additionally move the rim to the hub.

In addition, when tensioning the spare parts, they are also used to seat them. To this end, forcefully press on the spokes where they intersect, then turn the wheel and repeat the procedure in order to shrink all the spare parts in this way. Usually, with a successful procedure, the spokes emit characteristic sounds.

Often, it is better to rely on professionals to replace and tension spokes on a bicycle in order to be sure of the result. Unfortunately, sometimes improper repairs can only exacerbate problems and even lead to “eight” wheels, so if you have the slightest doubts, it is better to give the rover to the bike workshop.

Spokes for bicycles

A bicycle spoke is a structural part of a wheel, which is technically the rod that connects the hub and rim. Spokes, without sacrificing strength, make the wheel structure lighter.

These bike parts today are made from steel (stainless and chrome-plated carbon), titanium, carbon fiber and aluminum alloy. The most popular among cyclists are knitting needles made of stainless steel: they are inexpensive and durable. Additionally, parts made of steel are nickel-plated or chrome-plated. The spoke is connected to the hub and the wheel rim when the nipple is activated, into which it is screwed.

Is it possible to make a spoke wrench with your own hands?

It is impossible to imagine a cycling enthusiast’s toolbox without a spoke wrench. No one is immune from wheel impact, often there is a need to fix a spare part on the road in order to prevent friction of the rim on the frame or brake pads.

It is recommended to repair the consequences of an impact at home, preferably using a machine, but preliminary work can be done right on the road.
