How to fix a bicycle chain

How to eliminate brake whistling?

Do not repair the whistling or grinding noise of the brakes with grease. Never, under any circumstances, lubricate the brakes.!

Check that the wheel is properly seated in the mountings. Sometimes, when you install a wheel and tighten the locking nuts, the wheel becomes at an angle. This also changes the load on the brakes, which can lead to whistling. Also, the tire can touch the frame.

Check that the wheel is level. Over time, under loads, the wheel can begin to drive and the so-called “eight” appears. To determine the problem, secure the bike to a rack so the wheel can rotate. Spin the wheel and watch its behavior.

If you have rim brakes, look around the pad area above the rim. If during rotation there is a noticeable movement towards the pads, then the wheel rim needs to be aligned.

If you have disc brakes, then look in the area of ​​the disc and the pads on it. There may be problems with the rim or with the brake disc. These problems are easy to distinguish from each other. Sometimes you can even straighten the disc with your hands.

If everything is in order with the wheels, then do the following.

Clean the dirt from the rim or disc and the pads. This can be done with rubbing alcohol or a special liquid. The main thing. no grease or grease!

Additionally, you can sand the block (not a disc or rim!) With a coarse emery cloth. On disc brakes, it is more convenient to do this by removing the pads.

bicycle, chain

Check that the pads are not worn out too much. The pad cover must be thick enough so that the metal pad mount does not touch the rim or brake disc. Most rim brakes have markings on the pads to indicate that it is time to replace.

For disc brakes, the check is best done by removing the pad. General rule. the thickness of the pad together with the metal base must be at least 3mm.

Check pad alignment. This applies exclusively to rim brakes. If the brake pads are parallel to the wheel rim and touch the entire surface at once, this can cause the pads to whistle. It is necessary to bring the front ends of the pads a little so that they touch the rim a little earlier than the rear. This can be done by using the shoe fixing screw on the wheel.

How to remove seatpost creaking

Imagine! This under-seat tube can squeak too! There is nothing to break there, but it creaks. The creak then goes from the point where the pin enters the mount in the bike itself. It is recommended to remove the tube and thoroughly wipe the joints on the pin and inside the attachment point. dust could get there. Next, you need to apply a small layer of grease to the attachment point and install the pin in place. Remember to tighten the fastener carefully.

How to remove a creaky bike saddle

Again it creaks, shabby. And fiddles. Need to do something. Usually, a squeak appears due to the fact that the mount is loose. Tighten the mounting bolts with the appropriate wrenches and the squeak will pass. But fiddling again? Then it is recommended to unscrew the mount and re-install (almost like restarting the computer, yeah, sometimes it helps, almost always helps). Pay attention that the seat does not nod or bulge up. it will be unpleasant to drive, and sometimes traumatic. Also, make sure that the mount does not go beyond the limit marks (there is almost always on the seat). this can create additional stress on the structure.

How to eliminate chain snapping?

If the chain clicks loudly enough while driving, this may be a sign of poor transmission setup. It so happens that this is noticeable only in some combinations of forward and reverse gears. Make sure you don’t use extreme combinations that unnecessarily bend the chain. it’s just a misuse of mechanics. If noise appears on normal transmissions, don’t panic either. shifting is controlled by cables that stretch out over time, loosen up, and can get stuck in the shirt. There is nothing to worry about here. requires transmission regulation.

To adjust the transmission, on most derailleurs you need to turn the barrel nut where the transmission cable connects to the derailleur on the steering wheel. It is recommended to rotate no more than 1/4 turn at a time. Next, place the bike on a rack and, while rotating the pedals, change gears throughout the course. The chain should switch freely without sticking or scary sounds.

There is also wear and tear on the shift mechanism itself, which can be compensated for by repairing or replacing the mechanism. Alas, this is a mechanism and it is not eternal. Especially relevant for cheap switches of unknown origin.

My advice. all the same, go to the workshop and ask to set up the switch. The process is short-lived, inexpensive, and you are unlikely to be put in a queue. One more tip. check the switching after adjustment directly in the saddle near the workshop, because the transmission may behave differently from the rack if force is applied to it.

The bike squeaks, whistles and other sounds. How to fix?

What upsets any cyclist and hurts to the core? Right. extraneous sounds from your bike. What’s the best music for a cyclist? Silence in the work of his bike.

But annoying sounds. it is not only a depressing factor, it is also sometimes a signal that something is wrong with the mechanism. And the bike. it is a mechanism and, like any mechanism, is subject to wear and tear. And some damage to the bike can lead to damage to the cyclist and very serious. Therefore, do not ignore the signals that your trusty iron horse gives you.

Finding the source of the sound and the source of the problem can sometimes be difficult. It is best to drive into a quiet place and try to determine the source of the sound as accurately as possible, and then make a decision about the actions. In fact, most of these noises, and therefore their sources, can be removed quite easily with basic skills. But if you are suddenly unsure of your own abilities, take the bike to a bicycle workshop and describe in as much detail the nature of the sound and its approximate origin as possible. believe me, an experienced mechanic will be able to identify the problem by the diagnoses he encounters every day.

Opening the lock and squeezing the link axis

It is quite simple to open the lock: use a screwdriver or other object (for example, a knitting needle) to pry on the pincer clamp. The main thing here is not to damage it, or even better. not to lose it, otherwise it will not be possible to fix the chain later. Next, we decouple the entire link. That’s it, you can remove the chain and do whatever you want with it: clean it, throw it away or shorten it. However, we’ll talk about this a little later.

A solid chain can be disconnected only with a special tool. a squeeze. With its help, it will be possible to easily disassemble the link without damage. The procedure is simple, but you shouldn’t rush:

  • First, select the link for disassembly.
  • We insert the chain into the position of pressing out and pressing in the pin (link axis).
  • Use the handle to tighten the screw and take out the axle. Extrusion direction. towards the squeeze screw, that is, towards yourself.

You should not completely extract the pin, since it will not be easy to return it to its place later.

The squeeze will loosen the axle a little, so a different link should be selected when re-disengaging. Pressing the axle into the link is carried out in the opposite order: connect the adjacent links together and press the pin with the screw.

Is it worth repairing a bike chain on the road at all??

It is best not to repair the chain on the road. Repairing a chain is one of the dirtiest jobs. If you are wearing new clothes, then after repairing the chain, you can most likely say goodbye to it. Probably the best solution would be to call a taxi or attach your bike to the bike lock and go home by public transport. you will return later in your old clothes and calmly repair the chain.

How to replace a chain on a bicycle?

The chain is the key element of the bike’s transmission assembly. Sequentially passing through the teeth of the drive sprockets, it transmits torque to the rear wheel, thanks to which the bike rides. In the process of movement, the chain mechanism is subjected to dynamic loads, which over time leads to its wear.

On singlespeeds, as a rule, the chain is designed for the entire life of its operation: when moving along the stars, it walks smoothly and straight, without deviations. Chains are more complicated on multi-speed bicycles: there is no right angle between the front and rear sprockets, which is why it is always at an angle relative to the frame. The stresses on the chain mechanism increase several times compared to parallel transmission, which leads to periodic wear. To avoid damage to the entire transmission unit caused by wear of the chain, it must be replaced in time.

Not only does the speed chain need to be removed, it is quite common to remove it from single speed bikes for periodic repairs or cleaning. How to remove the chain from the bike and put it back, we will tell you in this article.

Lock and solid chain

The locking chain is equipped with a special clamping device. It is not difficult to unhook and put on it. you just need to disconnect the lock. To find it, we carefully examine the chain on both sides and find a detachable link. In principle, it will not be difficult to find it on a clean chain: a tick is put on top, which fixes the link and does not allow it to move apart. Also, the manufacturer’s inscription is usually embossed on the key link. If you cannot find the lock for a long time, then either the chain is dirty, or it is lockless, or solid.

A bicycle chain without a lock simply cannot be disconnected: all the links on it look the same, however, and are hooked to each other too. This is a big inconvenience when cleaning, for example, it is necessary to carry out a general cleaning in a solvent. In the case of the keylock, everything is simple. I stole it and put it in kerosene. Solid bike chain, even taken off the stars, will remain hanging on the frame.

In terms of removal, a chain with a lock is, of course, more convenient than its counterpart. However, for some reason, the fastening may loosen: the tick fly off, and the link itself can be disengaged. There are no such weak points on bicycle chains without locks, and if it is torn, then the point is solely in its quality.

The text was written by a 14-year-old schoolboy. YC-327 is a piece of Chinese g, which collective farmers who drive Auchan like to buy. The pins are skewed at times. Although, if you use it at Auchan, then maybe there will be norms. work. G c g compatible.

I bought a squeeze of Nautilus II BTL-05, I had to fix the chain for the first time, so my pin went crooked. Only now I did not bent the wall, but the squeeze itself. Then I went to a friend, he was 6 years older than me, gave me the squeeze YC-327. I liked the squeeze very much, it may not be so convenient to work with it, the handle turns harder, but it is reliable. highly. But in general, with the old squeeze (Nautilus II BTL-05), my pin constantly flew out, because it was simply inconvenient there due to the pin being held by a spring, so that it would not fly away when you pulled it out completely and I simply did not feel the pin. In short, this squeeze (Nautilus II BTL-05), which costs 1000 rubles, may be good, but I’m so crooked, but it’s definitely not worth my money, so take the YC-327: D, Now I’m very sorry for the money spent, but it was a good and rewarding experience. Then I had another squeeze, even more expensive, but soon it was also bent: D. It’s just that. that in expensive pomace the chain rests on the legs and if the pin goes crooked, then most likely you will bend the pomace, and for the YC-327 the chain rests on the body itself, and the legs are needed to fix the chain and so that it does not go to the side, so that it bending or breaking it is almost impossible.

How to repair a bicycle chain

With proper preparation, repairing a bicycle chain on the road is as easy as sticking a bicycle tube.

What you need to repair your bike chain.

To repair a damaged bike chain, you only need a chain fitting tool. It is compact and usually found in many multi-functional bike repair tools. Perhaps a similar tool is included in one of your multifunctional tools and you simply did not know what it was for.!

At home, repairing a bicycle chain can be done with a hammer and pliers, but you can’t take them with you on the road. On a trip, the chain will only have to be repaired with a lightweight chain mounting tool.

The chain flew

Let’s see why the chain flies. There are two options: either you have a bent sprocket on the system (the system is a front set of sprockets), or the speeds are poorly adjusted.

If you have a bent star on the system, in this case you can continue moving simply by switching to a different speed at which the star is not bent. But if you use all the speeds while driving, then in the future you will have to replace the bent star. If the system is collapsible, you will only be able to replace one damaged star. If the system is non-separable, you will have to change the entire system along with the connecting rod.

If everything is in order with the connecting rods (what is a connecting rod?), Then your speeds are poorly set. On each of the derailleurs, both front and rear, there are adjusting bolts that prevent the chain from going over extreme speeds. If they are incorrectly adjusted, then the chain will fly off. If the chain falls off the largest sprocket, then you need to screw in a bolt with an L index, which means low. the lightest gear.

It must be screwed in until the stars on the switch are parallel to the large star. The same from the reverse side: if your chain flies from the smallest sprocket, you need to screw in a bolt with the index H (high).

Screw it in until the switch is parallel to the seventh speed.

If at the front the chain falls from the small chain to the frame, then tighten the bolt low.

To properly adjust the bolt labeled low, you need to set the lightest speed on the bike and screw it until there is a gap of 1 mm between the inner derailleur frame and the chain.

If the chain falls from a large sprocket to the connecting rod, then screw in the high bolt.

To properly adjust the high bolt, set the bike to the fastest speed and tighten it until there is a 1 mm gap between the chain and the outer derailleur frame.

These were the most common reasons for chain failure. Now let’s talk about her breakup.

The chain breaks as usual?

often than not, the chain breaks when you pedal at full power and simultaneously shift the gear on the front derailleur. Other causes of chain breakdowns are very rare, one in a million at best. You only get a chance to meet them if you bike a lot. For example, a nail flew out from under my front wheel, hitting the chain and hitting the sprocket. Who would have thought that this could happen?

When do you need to remove the chain from the bike?

Let’s figure out how to know if the chain assembly of a multi-speed bike is faulty. You can estimate the mileage of a two-wheeler, but other factors also affect the health of the cycle.

How to Replace a Chain on a Bike. Sizing & Installation

  • Correct selection of gears;
  • Pedal load;
  • The quality of the roads;
  • Driving speed.

The appearance of suspicious sounds (provided that the lubrication is in order) and difficulty shifting gears are the first signs of a chain assembly malfunction. The simplest way to assess the health of links is as follows:

  • Peel back the bike chain from the largest sprocket;
  • If it leaves freely from 3 or more teeth, then the bicycle chain must be replaced. Two prongs are a kind of warning. You can still travel for some time, but it will have to be removed soon.

The same method works for single speed bikes.

An informative method is measuring the length of the bike chain.

  • 30.5 cm is the best length;
  • 30.6-30.8 cm. medium wear, high maintainability;
  • than 30.8 cm. the links and sprockets are badly worn. The entire transmission is damaged.

To correctly measure the relative elongation, the chain must be completely removed from the bike.

Solid

It is impossible to completely remove such a cycle. If you remove it completely from the sprockets, it just hangs on the frame. Of course, compared to the version equipped with a lock, the solid construction is less convenient. However, there are also advantages. The lock can loosen, the connecting plier can be lost. The links are disengaged. There are no such problems with a continuous chain. If it burst, then this is exclusively a quality cost.

The work has been completed. As you can see, there is no difficulty in removing the bike chain and putting it back on. It remains to check the correctness of what was done by scrolling the pedals. If the cycle runs freely, but without sagging, then everything is done correctly, and its length is optimal.

Disconnecting a chain with and without a chain installer.

To start pushing the pin out of the chain, turn the handle on the chain installer (see photo). Try to align the axle on the chain mounting tool with the pin on the chain (sometimes it slips a little).

Do not push the pin all the way in. push it in just enough to disconnect the circuit (see photo). The remaining piece of pin must be left in the chain so that it can be easily pushed through later.

If you do not have a tool to install the chain, then you will have to find a piece of wood and drill a small hole in it. Place the pin to be removed over the drilled hole. Find a small mounting screw about the same size as the pin and use it as a stud. Hit it with a hammer to knock the pin out of the chain to the required distance. Beat him very carefully so as not to knock him completely out of the chain.

Lock

Its peculiarity is that it has a special clamping device. Removing one from the stars, as well as putting it back on, is not difficult. To do this, you just need to disconnect the lock.

You can locate the detachable link by visual inspection. If the links are clean, finding the connector is easy. As a rule, the manufacturer’s brand is stamped on the connector.

Repairing a broken bike chain

There are unpleasant moments, you ride calmly on the bike, the weather is wonderful, the breeze in your back, the sun is beautiful, BAM touched the urn or just a clap and the pedals are scrolling, but you continue to eat, but there is no more tension! On the brakes and the chain is not there, it lies behind you in five meters as a dead snake panic in your head, what to do, what a pancake, what to do, drag it to the service, throw the bike into the river !? Without panic, a tricky device called chain squeezing will help you.

In addition to the squeeze of the chain, kind people carry with you a piece of chain with the same indicators, or better the same. When I adjust a new chain to fit my needs, I do not throw out the remaining chain, but carefully put it in a bag and carry it with me just for such cases. Or if you were given a new chain, then ask the kind doctor aybolit to leave the organ in your memory, you will pack it up and take it with you as a talisman. And if the bike was new and you don’t know that there is a chain on it until it breaks, then we will use plan B.

The allegory on the topic of squeeze is over, the access has been chosen, paid in gold, now you are the lucky owner of metal crap. They drove to twist the chain, with songs, dances, good mood and a bottle of sweet soda. Remember brother, a cyclist, the first time you get it only with a hardened rider or cyclist whose spirit has reincarnated in your body. If something does not work out or the iron falls out of your hands, do not worry and save STIHL! Everything will work out for sure, since you set out to do it yourself and read this text, the result will be positive. Positive charge received let’s get down to business.

If something does not work out or the iron falls out of your hands, do not worry and save STIHL! Everything will work out for sure, since you set out to do it yourself and read this text, the result will be positive. Positive charge received let’s get down to business.

The purpose of the repair is to knock out the broken link and add a new one. Know the chain is dirty by its nature, and your hands will be in oil up to the elbows. Wear gloves or a rag. I adapt a wrench or a screwdriver to manipulate the chain, it is easier to wipe off oil with a screwdriver than to wash it off my hands. We take the machine in the right hand, the chain in the left. We place the chain on the walls of the machine as shown in the picture. We dress it on the wall closest to you. If you put it on the far one and when you start to squeeze out the pin, there is a chance that you will break the wall. So be careful. We put the chain on the last link before the broken one, from centering the chain relative to the retractable sting of the machine, took the whole system by hand so that it would be convenient to rotate the lever.

Next, we begin to rotate the lever, do it smoothly, take your time. When the tip comes into contact with the chain, stop the rotation and check if you hit the pin. Ideally, this is when the sting hits exactly the middle. If you are sure that the sting is in the center of the pin, continue to rotate the lever. It will go tight at first until the pin passes the first wall of the chain. After passing the first grid, you will feel a sharp relief in the tension of the chain. Next, there will be the second wall of the chain, through which the pin passes more easily. Continue to rotate slowly and carefully.

As a result, we get a pin that is not fully squeezed out. I will explain why you need to squeeze the pin to yourself and not from yourself. This will make life easier for us at the stage of pressing the pin. In the opposite direction, it will be very inconvenient for us to insert it (checked =)

We carefully unclench the chain, release the inner row.

Next, we do the same procedure as we did earlier. We take the link we need, check what will happen after squeezing the pin, making sure that everything will be the way we proceed to squeezing.

We squeezed the pin out of the second link there it can be squeezed out completely. They unclenched the insides fell out, we will no longer need them. We wiped the seats with a cloth so that the correspondence could be seen better. As a result, after all these procedures, you get such a neat riveted chain without a broken link.

Next, put the riveted chain in the machine as shown in the photo. The inner chain was inserted. They leveled, from the center took everything into their not trembling hands. I went to the press.

We press smoothly, listen to the chain, after passing each wall, the pin will enter tighter and tighter. Make sure the pin goes smoothly. Press in a parallel plane to the floor, do not allow the chain to bend. It is better to check once again, unclench the sting and make sure that the pin goes smoothly. How to understand that the pin bent the shit and what to do now? It is very easy to bend the pin, if at least a little bit against one of the walls and you do not notice it and continue to drive it deeper and deeper, after a couple of turns it will simply stupidly bulge the wall or bend it or bend itself / A bent pin is an ASS! So we press it carefully.

In general, disassembling and assembling the chain is not difficult. I am in a good mood and to the music I do this whole thing on the street in 10 minutes. I always carry a couple of pieces of chain with me for myself and for my brother, a cyclist who broke the chain and doesn’t know where to go.

Smooth road and fair wind! Article prepared by Bankay78

Any vehicle needs maintenance. Bicycles are not exempt. Their key element in the transmission unit is the chain. Speed ​​bicycles are inherently finicky to function properly. The frequency of chain replacement or maintenance is largely determined by the riding style. For example, trial cycling enthusiasts do this while riding. When and how to change the chain on a speed bike?

Bicycle chains come in two types: lock and solid. Disconnecting the lock variation is not difficult. It is convenient to do this with a regular thread (wire), threading it into adjacent links (before and in front of the lock) and tightening the loop. The main thing is to avoid damage to the lock and not lose it.

Opening a continuous chain is possible only with a special squeeze, although the procedure itself also cannot be classified as complex tasks:

  • It will be necessary to install the chain in the position of pressing out-pressing in the axle.
  • Tightening the screw to pull out the pin.

Axial pressing is inherent in the opposite sequence: connecting the links and pressing the pin by means of a screw.

What tools are important to have to replace the chain:

  • The key used to remove the rear wheel.
  • Pliers to hold segments and pins.
  • Squeeze. As noted above, this device is used to press out and press in the pins.

Cyclists who do not have sufficient experience in such matters are advised to memorize the general diagram, reflecting the location of the chain on the system, cassette, switches. Then the procedure for its subsequent installation will not cause difficulties.

As soon as all the nuances are fixed in memory (or on paper), you can proceed to further steps:

This completes the removal of the chain (worn out or requiring cleaning). The procedure itself is quite easy if you have a tool and basic knowledge. Accuracy of execution and the absence of forceful actions during the extrusion process are very important.

With bicycles that have one gear (singlespeeds), everything is limited to the canopy of the chain on the part of the star configuration and the locking snap-in or pressing in the pin. The design of high-speed bikes suggests some difficulties in this issue.

They can be designated by the following points:

At the final stage, the move is checked. For this purpose, the pedals are rotated. Incorrect installation is characterized by sagging of the installed element and difficult twisting. If this is not observed, the installation of the chain is done according to all the rules.

In what cases, in addition to wear, the chain is removed:

  • For deep cleaning when it is necessary to remove lubricant and accumulated abrasive.
  • To replace damaged links.

A failed chain stretches, its links shift, harming the sprockets, which negatively affects the switches. It is quite difficult to visually determine the degree of wear.

Therefore, they use a simple measurement, that is, you need to measure twenty-four links, or rather their total length:

  • With a value of 30.5 cm, we can talk about the normal state of the chain.
  • An indicator of 30.65-30.75 cm indicates the need for replacement.

By the way, cutting the stretched chain does not solve the problem. Stretching is characterized by an even distribution. In this case, damage to the stars cannot be avoided. As you know, stellar parts cannot be repaired. It is cheaper to change the chain than to replace more expensive components.

How to Fix a Broken Bicycle Chain

How to start repairing a bicycle chain.

Let’s say you’ve changed into your old clothes and are ready to get to work. To make it easier for you to inspect the chain. turn the bike over.

Inspect the two broken ends of the chain: one end (and possibly two) is damaged and needs to be replaced. You will have to remove two chain links from the damaged end of the chain. Why do you need to remove two links, and not one. you might ask? Since the chain consists of two types of links, if you remove only one link, you will not be able to connect two links of the same type.

Where the chain needs to be opened, place it in the groove of the chain mounting tool (see photo). The same procedure applies when repairing a worn chain.

Very useful videos about bike repair. Well told and shown! Thank you very much! Be healthy and keep up the good work!

modern chains are not very durable, even the campagnola was blown away))
