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.
Without the bullshit. How to build a 36 spoke wheel.
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.
Features of radial lacing
Experienced specialists use this type of lacing mainly for the front wheels. This is explained by the fact that they are less subject to stress from the pedals and brakes. But, despite this, the wheel receives a colossal load, which is directed vertically. That is why, with radial lacing, a large number of knitting needles are used. Mechanics recommend the optimal number of spokes 32.
It is worth noting that with this method of lacing, it does not play a big role where the spoke head is facing. At the request of the cyclist, it can be directed inward of the hub flanges, and outward.
Radial runout (ellipse, egg)
To edit the eight, popularly called the “egg” is somewhat more difficult.
First, remove the tire to make sure the curve is a rim and not a 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.
How to build a Bicycle Wheel (32 Spokes, Rear wheel, 26″)
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 turns so that there is no figure of 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.
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;
Causes of wheel deformation
There can be several reasons due to which the wheel is pretty bent:
- This is, of course, the weight of the cyclist, which puts stress on the wheels day in and day out. Since a person’s weight can be different, then the load, respectively, is also different.
- Harsh braking of the bike can put additional stress on the wheel spokes.
- Sharp turns in the path of the cyclist can also cause deformation.
- Uneven terrain on which the bike rides often leads to wheel problems.
- A hard hit or fall is likely to lead to the so-called eight.
- And in the end, just loose spokes will lead to nothing more than wheel deformations.
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.
Stage two: Installation
For successful wheel packing you will need:
- Knitting needles;
- Spoke key;
If this is the first time you have to re-spoke a wheel, then pay special attention to the fact 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 hole, which is located next to the valve hole. The nipple must be closed a few turns so that the spoke cannot fall out. The next spoke should be directed into the hole in 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. It is necessary 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 in the second hole after the spool, then the first spoke of the left flange should be located on the left.
When all the tail needles are in place, you can move on to the leading ones. We turn the bicycle wheel towards us with the right flange. The leading spokes are installed from the inside of the flange. They can be inserted into any hole. After that, turn the hub clockwise so that the leading spoke intersects with the three tail spoke. It is important that it crosses the first two from the outside, and the third from the inside. You may need to bend it slightly to install. There is nothing wrong with that. The rest of the leading spokes are installed in the same way.
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.
How to properly re-spoke a bicycle wheel
Wheel lacing is a problem that will sooner or later face any cyclist, regardless of the experience and skill level of cycling. Collecting a wheel only at first glance may seem like a daunting task. You should have patience and time. everything about everything will take at least an hour, or even two or three. By the way, self-assembly of wheels is also good because for yourself you will never cheat and, in order to save time and effort, skip some operations.
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.
Stage three. Tension adjustment
The first step is to make an initial adjustment, which involves tightening all the nipples evenly. Be sure to make sure that all nipples are screwed in the same number of turns. the spokes must have the same tension. Typically, the lead spokes are curved close to the flange. Before starting the tensioning procedure, they must be folded by hand by pressing on each spoke near the flange.
The final tension should be applied after the initial adjustment has been completed. Correct tension will ensure that the wheel does not run out when driving, which is very important for comfortable movement.
Summing up, we can safely say that wheel spokes are far from the most difficult procedure. If you are sure that you can handle the knitting, have sufficient patience, skills, knowledge and skills, then this procedure will not be a problem.
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 with 36 spokes and 3 crosses, then the second hole is chosen 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 spoke 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 lacing. assembly instructions
The essence of our method is that we first have to spoke the wheel on one side, and then on the other (spacing 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 must 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 spacing (how to assemble a wheel). It will also be helpful to read how to choose bmx for beginners.

Select a hole in the free flange of the hub and run a spoke from it into the hole in the rim. How to latch the wheel correctly? Matching takes patience, just like 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 that 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!
