How to change a spoke on a bicycle?
Has the spoke broken? Our video tutorial will make it very easy to replace it. Bicycles shake and crash on paths and uneven roads, and a loose or broken spoke is the most common problem.
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.
Tools for the job
- Spoke wrench;
- Tire blades;
- Flat screwdriver;
- You may need a retaining ring puller or a short piece of chain with a handle to remove the sprocket block, depending on where the spoke is broken;
- Spare spoke.
How to replace a spoke?
A broken spoke is unlikely to jump out of the wheel, so you need to fix it or remove it to get home. You can screw it onto an adjacent spoke or tape it to it, or if you have a tool at hand, just bite off.
You will probably have to remove the brake disc and for this you need special torx wrenches (sprockets), instead of the usual hexagons. Be careful when removing these bolts and when reinstalling them, be sure to use Threadlock or anti-tack compound to prevent bolts from getting stuck.
Deflate the tire and remove the tube when not using a tubeless tire. Lift up the rim strap and remove the coupling nut and spoke fragment from the wheel. Remove the remainder of the spoke from the corresponding lug on the hub. 3. Now you need to insert a new spoke. With a “three-cross” spokes of the wheel, you need to draw a spoke over the first two and below the third nearest spoke. Alternatively, the wheels can have a “double-cross” or “straight” spoke configuration, so match the spoke to the adjacent spoke. 4. Now you need to install the union nut. To facilitate this task, insert the spoke into the hole in the rim and tighten the nut. Pull the spoke and hold the nut with a screwdriver until the spoke is fully tensioned. 5. Rotate the nut with a spoke wrench until the spoke is fully tensioned. Remember to rotate counterclockwise when viewed from the rim side After installing a new spoke, it is a good idea to send the wheel to the adjusting machine, as broken spokes are often caused by incorrect adjustments. If you do not want to carry out the adjustment process completely, you can get a rough idea of the correct tension by squeezing the adjacent pairs of knitting needles with your fingers.
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.
If you have an ordinary figure eight, that is, lateral runout, then there is no need to remove the tire. Just turn the bike upside down and sit next to it, the process will be long.
The first step is to determine the degree of curvature of the rim. If you have vibrake, then everything is simple. bring them to the minimum distance so that the rim only slightly touches the shoe in the most protruding place. Scrolling the wheel, you will immediately see in which direction the rim led.
If the brakes are disc brakes, then put something like a screwdriver or a handle on the feathers and bring it to the rim. At this stage, we just look at how much the curvature is and in which direction.
Take the chalk, and resting your hand on the feathers, lean it firmly against the most protruding section of the rim. Rotate slowly, making sure that the hand with the chalk is still. Thus, it turns out that in the place of the greatest curvature, the chalk trace is most pronounced, losing strength and completely disappearing to the edges of the figure eight.
Determine the center of the figure eight, and find the most central spoke. If the rim is pulled to the right, then this spoke will attach to the right side of the hub, and vice versa.
Logic dictates that the side in which the rim has gone should be weakened. This is correct, but the trick is that the opposite side must be pulled simultaneously with exactly the same amount of effort. If you do not do this, then the rim may lead in a radial direction, and it will be more difficult to straighten it.
Loosen the center needle of the figure eight (in our case, the one on the right side of the hub) by half a turn. The trick: always with knitting needles you need to do this: if you want to turn it half a turn, then turn it three quarters and return it a quarter back. This is necessary in order for the nipple to “sit down”.
On each side of the center knitting needle (we have the right one, since the figure eight is right), two knitting needles will be left. Pull them exactly the same number of turns.
Move on to the edges of the figure eight (just do not confuse which knitting needles you have already touched). But with each new “layer” of spokes, reduce the number of revolutions. If, for example, you started with a half turn, then you can finish with 1/8.
Now spin the wheel, press the chalk again and see what happens. It won’t work very well at first. If you overdid it, then the figure eight can take the opposite direction, it can also split into two small eights.
Keep up the good work until you have captured everything. For disc brakes, you can not try too much: minor eights can only influence the opinion of aesthetes. On vibrating racks, you need to bring the rim to perfect condition.
When, after all, after a long time you managed to achieve your goal, remove the wheel from the frame, remove the eccentric and lay it on the floor, flat. Leaning the sleeve on the floor, grab the rim with both hands and push with all your weight on the wheel. Then grab another place on the rim and repeat. Then flip the wheel and start over.
You can hear a crackling. do not be alarmed, the spokes are shrinking. After such a procedure, you need to check again for eights, and if something manifests itself, then again correct and “seat”.

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.

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.
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.
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.
The main types of wheel spacing
There are two main types of knitting:
There are several more names that are a refinement of the pattern resulting from the spokes of the wheel:
- Twisted knitting needles.
Types of fasteners
To understand how to remove cranks from a bicycle without a puller, it is important to understand the types of mounts that are used to connect the part to the sprockets. Modern products can be installed using nuts, splines or fasteners made in the form of specific squares. Rotary joining is also available today.
Types of connecting rods
- One-piece. presented in the form of a monolithic structure, where the left and right elements are fixedly mounted on the axis. The advantage of this solution is high reliability, ease of maintenance and low weight due to the lack of fasteners.
- Two-piece. the axle, the right connecting rod and the drive sprocket are combined into a single structure. Left connecting rod attaches to the system thanks to a nut fit.
- Three-part is the most common option. Presented as a separate axle, as well as right and left connecting rods connected to a sprocket.
What are connecting rods?
The connecting rod is a part that carries one of the most significant loads during movement. There are blocks of chainrings that are motionlessly connected to the connecting rod. In this case, if a breakdown occurs, it is necessary to replace both connecting rods. On bikes in the upper price bracket, the stars can be changed by disconnecting from the connecting rod as they wear out.
Questions regarding how to remove the cranks from a bicycle without a puller begin to bother bike owners in the event of damage to these parts. It is necessary to dismantle the element in order to gain free access to the carriage when adjusting it.
During travel, the cranks are subject to the highest load. Therefore, solid steel is most often used as a material for their manufacture. Recently, products made from aluminum alloys have been in high demand. Most often, such solutions are used when completing sports bicycles, where reducing the total weight plays a decisive role.
Removing the connecting rods from the bike without a puller
In cases where the cyclist does not have access to a specialized tool, there are comparatively few options left to accomplish the task. To remove cranks from a bike without a puller, you can use the following solutions:
- Try to forcefully dismantle the connecting rod. Of course, in the case of using a sledgehammer, there is a high probability of causing irreparable damage to the bearings and carriage. Although the idea may pay off, it may be because of your own laziness that you will have to resort to additional costs for repairing other parts.
- The second option involves abundant treatment of the joints with lubricants, followed by unscrewing the bolts. With the fasteners released, it is enough to ride a bicycle a few hundred meters, applying maximum pressure on the cranks.
In what situations it may be necessary to dismantle the connecting rod?
The connecting rod is a fairly simple part that does not need much maintenance and care. Component replacement is most often done due to mechanical damage. The need for removal may also arise when it is necessary to gain free access to the carriage, perform adjustments or flush the system.
Often, after driving in rainy weather, unpleasant squeaks occur in the carriage area, the cause of which is the ingress of sand and dirt into the nodal mechanism. In this case, it may be necessary to remove the connecting rod to clean the seat.
In general, the connecting rod itself is not dismantled. To do this, resort to the operation of a special puller or the use of improvised methods, which will be discussed below.
How to remove connecting rods from a bike without a puller. helpful tips
The question of how to remove the connecting rods from a bicycle without a puller arises in situations where it is necessary to dismantle the specified part for replacement and maintenance. To remove the node element in a professional environment, specialized pullers are used. However, if you wish, you can do without it. Let’s figure out how to remove bicycle cranks without using a puller.
Installing the connecting rod
After dismantling the part and performing all the planned manipulations, it is necessary to return the structural element to its original place. Before carrying out work, it is advisable to clean all surfaces and joints, and then process them with a thick lubricant. This approach will allow the connecting rod to be installed evenly and will greatly facilitate the work if it is necessary to dismantle it again.
During installation, the part must be deeply fitted onto the shaft. This will avoid the appearance of backlash during movement. If the connecting rod is not firmly fixed, the socket will gradually become unusable. For reliable fastening of the part, a force of about 50-70 Nm is sufficient.
