How to assemble the spokes on the rear wheel of a bicycle

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.

How to edit eights on wheels and change spokes

Among novice cyclists (and not so much) there is an opinion that editing eights is something bordering on magic, and an ordinary person does not need to do this.

When my first collapsing 100lb bike started to hit the rim of the vibrake with the rim of the eights because of the eights, I had to do something.

All agreed in one opinion: a specialist should rule the eights, otherwise “it will be worse”. What could be worse, when everything was already very bad for me, I did not understand. Therefore, I bought a key for the knitting needles, sat down on the Internet and began to put into practice the instructions I read.

The most surprising thing for me was that I straightened the eights. The very first time. And I hope with this article to prove to my readers-novice cycling enthusiasts that it is not at all difficult. I don’t mean to say that I became a wheeled guru. On the contrary, I do not know how to assemble wheels from scratch. experience and flair are needed here.

Let’s start. Of course, you do not have a wheel assembly stand, so you only need a spoke wrench and chalk from the tool. Do not try to twist the spokes nipples with pliers. you will tear off the edges.

Stage two: Installation

For successful wheel packing you will need:

assemble, spokes, rear, wheel

If you have to re-spoke a wheel for the first time, then pay special attention that the holes on the rim are slightly offset (tilted) to the sides. The spokes from the right flange of the hub should be inserted into the holes that are offset to the right, and from the left flange to the left. Half of the spokes on each flange are leading. The other half is tail.

  • Leading spokes are those that point in the direction of rotation of the rim. As a rule, they are indicated by shades of blue.
  • The tail spokes are against the rotation of the wheel. Most often they are indicated by shades of red.

The first is the tail spoke, which must pass inside the flange. It should be inserted from the outside of the right flange and directed into the offset to the right of the rim bore, which is located next to the spool bore. The nipple must be closed a few turns so that the spoke cannot fall out. The next spoke should be directed into the hole of the same flange, the next spoke through three holes after the first installed.

The next step is to turn the bicycle wheel so that it is in front of the left flange of the hub. The second set of needles inserted will also be the tail needles. You need to turn the rim so that the spool is at the top. We pay attention to the very first installed spoke. if it is in the first hole after the spool, then the first spoke of the left flange should be located to the left, if the first spoke installed in the second hole after the spool, then the first spoke of the left flange should be located on the left.

And if it is enough just to pull up a loose knitting needle, then a bent or broken one must be urgently changed.

Fortunately, changing a spoke is as easy as it is cheap, and with a video tutorial, you’ll be back on the road in no time.

Stage one. Determining the Right Needle Length

It is very important to choose the correct length for your bicycle spokes. In this regard, much less problems arise with the front wheel. here the spokes on both sides have the same length. With the back, everything is much more complicated. Multiple speeds set on the rear wheel make centering difficult. The needles will have different lengths and angles. To determine the appropriate length, special calculators have been created that allow you to calculate the required parameters online.

What is the spacing

There are two most popular types of wheel lacing. radial and cross. Radial lacing is only used for assembling the front wheels, which will be equipped with rim brakes. The radial pattern has a significant drawback. a wheel with such a spoke is subjected to the highest load in the vertical direction. And, perhaps, the only advantage of this option can be called a pleasant-looking appearance.

Far more versatile and functional is the cross lacing. Cross lacing may look less impressive, but it allows you to achieve the most adequate response to the braking and rotating forces from the hub. With this option, even the most serious load from braking and pedaling is transferred to the stretching of the spokes.

Mixed lacing is rarely used. This option is somewhere between the radial and cross methods.

Having decided on the type of spokes, you can safely begin the process of assembling the wheel. It is divided into several stages.

Sequence of work

Initially, you should dismantle the wheel and install it in a special device that allows you to balance it. If you are unable to locate such a device, simply turn the bike over and place it on the handlebars and seat without removing the wheels. To check how the spokes are tensioned, we make a swinging motion. Thus, it is necessary to check all the elements, the deviation of the free stroke should not exceed 2 mm.

Each problematic part should be marked with, for example, a piece of electrical tape.

Using a special wrench, tighten the loosened elements to the required level, everyone needs equal tension. Tensioning these structural elements on a bicycle should be the same length, in order to understand whether you did it correctly, it is enough to count the number of threads remaining after tensioning the nipples.

If you do not initially set the nipple tension at the same level, you will not be able to get a reliable picture of the curvature of the rim.

After full stretching, most likely, a figure-eight curvature of the rim will appear, horizontal beating may appear. To eliminate these problems, we use a special centering device. If there is no device, it is necessary to determine the boundaries of the curvature with the help of chalk, for which we
fix the chalk so that when the wheel turns, a trace remains on its rim. Thus, we find the peak of the deviation, with which we will have to work in the future.

If you find a hump on the right side on the width of four spokes, tighten two of them by half a turn at the left flange. Give two more pieces at the right flange half a turn. Thus, we achieve the alignment of the rim to the left. If there are not four, but three knitting needles on the hump, pull the first one half a turn, and release two by a quarter.

By following these steps sequentially, you can eliminate the horizontal curvature in the form of a figure eight.

To start debugging the rim and eliminate the vertical runout (ellipse), it is enough to reapply the chalk, but this time we move it from the edge of the wheel to the center, determining the strongest deviation as a result. The strongest deviation, determined as a result of the shallow check, is eliminated by tensioning the nipples where the bushing hole is. When there are three knitting needles in the place of the problem, we tighten the middle one half a turn, and lower the outer ones by a quarter. With an even number of parts in the center of the curvature, all are tightened by half a turn.

After correcting the misalignment of the rim, it is recommended to re-check the tension of all elements, and, if necessary, bring their tension to the desired level.

Causes of wheel deformation

There can be several reasons due to which the wheel is pretty bent:

These problems are not so terrible and can be solved by re-spacing the wheels. It is best if the user knows the assembly of the bike and can handle it on their own, because no one knows where the problem may overtake. And, of course, in any service center, experienced specialists will provide a service for any type of repositioning.

How to tighten the spokes on a bicycle correctly?

Tightening the spokes at home is not an easy job and you will have to spend a sufficient amount of time on this operation, especially if you are starting the repair for the first time. To successfully complete this task, you should prepare special tools, without which you will not be able to tighten the spokes on the bicycle. To adjust the knitting needles you must purchase:

  • special key for adjustment;
  • a device that allows balancing;
  • a set of keys for dismantling the wheel;
  • screwdriver.

Where does the assembly begin

On the side of a bicycle wheel, start by selecting all the components and tools. In this case, the difference between the front and rear wheels must be taken into account. If the front is symmetrical, then with the back everything is much more complicated.

The sprocket drive makes it possible to take into account the possible nuances of the central hub. The main difficulty at this stage is to decide on the length of the spokes, taking into account the specified features of the front and rear wheels. As a result of the first stage, we have to select: a rim, an axial bushing, spokes with nipples of a suitable length, and from the tool. a spoke wrench and a screwdriver.

DIY bicycle wheel re-spacing step by step instructions

The whole process of re-spacing can, in principle, be divided into three stages:

  • Determining the Right Needle Length.
  • Installation.
  • Tension adjustment.

The correct calculation of the length of the spoke is calculated with a special very complex formula. But on the Internet, special programs have now appeared that will quickly calculate the length suitable for a given bicycle. The Lexapskov calculator is very popular. Users claim that this program is very easy to use and at the same time quite accurate in calculations.

Installation is a rather long and laborious process:

How to assemble a bmx bike wheel

Wheel spacing begins by first inserting 2 spokes into the hub in a crossed manner, as shown in the pictures. Ready to spoke the wheel? Then let’s move on. It is worth paying more attention to the fact that one spoke should go, as it were, inside the sleeve, and the other out. That is, in other words, you need to spoke the wheel by pushing the spokes through one on the opposite side of the flange. Now for the choice of the hole on the rim. We choose the first hole for knitting randomly. Since we are considering a method of assembling a wheel in 36 spokes and 3 crosses, then we choose the second hole the fifth in a row (on the right side) from the inserted spoke. This is clearly visible in the picture about how to assemble a bmx bicycle wheel. Remember, sturdy wheels will last longer if you practice tricks intensively, such as manual to 180.

Take a break, the game box 10 bmx is waiting for you. Then we insert the rest of the spokes in the same way, with each next one going into the adjacent hole on the rim (livebmx.ru advises not to forget about the right side of the spokes when assembling the wheel). Wheel spacing is not as difficult as it seems at first glance. The first time it will be unusual to assemble a wheel, but with experience you will learn how to spoke a wheel pretty quickly. When you have assembled all the spokes on one side of the flange, check this moment. Each spoke must have 3 crosses, with 2 crosses going on one side of the spoke and the third one closest to the rim going on the other side (the crosses are marked with arrows in the image). When assembling the wheel, tighten the nipples just a little at first. You will tighten the knitting needles at the very end (correct spacing and sequence of actions).

Wheel Spoke. Assembly Instructions

The essence of our method is that we first have to spoke the wheel on one side, and then on the other (according to the version of our site). As you can see, the spoke holes on the rim are not aligned in a straight line. Holes go through one, and each of them is closer to its edge (competent wheel spacing. 36 spokes in 3 crosses). To assemble a bicycle wheel correctly, you need to understand that the spokes from one edge of the flange (the flange is the part of the hub on which the spoke holes are located) must go into the hole in the rim from a certain side. You can see all this clearly in the pictures below, depicting a process called lacing (how to assemble a wheel). It will also be helpful to read how to choose bmx for beginners.

Select a hole in the loose flange of the hub and run a spoke from it into the hole in the rim. How to latch the wheel correctly? Matching requires patience, as is this article on how to assemble a wheel. If you look at the bushing from above, the holes on the opposite flanges are not level one above the other. If you take the hole a little to the left, then on the rim you need to find a hole that is slightly to the left of the spoke, which comes from the hole with which you are matching. In a similar way, try to assemble the wheel, or rather to latch the second part of it. After the wheel is spoked, tighten the spokes all the same so that there are no eight and an egg. And also remember to center the rim so that the rim is exactly in the middle of the hub, and not closer to one of the flanges. Note that new spokes tend to loosen, especially after the first assembly (spokes), so be prepared to tighten them after a couple of days of riding. Strong wheels and good assembly to all!
