How to untangle a bicycle chain without removing

How to install a chain on a bike

Before installing the chain, you need to make sure that it will fit your bike. A special axle with a pointed end is usually sold with a chain. It serves to facilitate installation, after pressing the axle, this end must be broken off with pliers. Also, the axle can be already installed in place if the chain is supplied without a special axle.

We connect the open links, install the axis. We insert the link into the chain squeeze and fix it with a fixing screw. Press the axle into place by rotating the chain release handle, it should line up with the edges of the chain. Remove the chain from the squeeze, if necessary break off the end of the axle.

Check that this chain link bends freely, if it runs tight, then it is necessary to adjust the axle with a squeeze. In this case, insert the link into the second seat of the squeeze, then you can see both ends of the axle.

Removing the chain from a bike

The need to remove the bicycle chain occurs when it needs to be replaced, washed thoroughly or boiled in grease (in the case of a single-speed chain). Therefore, a small beginner’s guide.

It is possible to remove the chain from the bike only by removing the axle connecting the links (pin). You can squeeze out the pin without a tool, right in the field by placing the chain on the edge of a hard object and tapping the axis with a thin knitting needle.

Unfortunately, this method will not allow you to assemble the chain back, because there will be nothing to press in the pin. Therefore, to remove the bicycle chain, you need to have a special squeeze device, it is best to take a multitool, which includes all the main bicycle keys, including the squeeze. I have one like this. very satisfied.

Place the chain link on the squeeze so that the pin is directly in front of the tool release axis. Then just gently twist the handle, and the pin is squeezed out.

The main thing is to stop at the end so that the pin does not pop out completely, otherwise then your vocabulary will not have enough swear words to push it back.

Below is a video showing what I’m talking about (1:05).

In general, ideally, I recommend putting the lock on the chain, this allows you to remove and put the chain on the bike instantly.

When installing the chain on a multi-speed bike, you need to follow the pattern of pulling along the rollers of the rear derailleur, I painted in red in this picture:

Everything is very simple, and there is absolutely no need to go to the bike master because of some minor problem with the transmission.

How to put a chain on a bicycle without a lock

Before reconnecting the chain on mountain bikes and sport bikes, it must be correctly pulled through the rollers. see fig. below, marked with a red line:

Next, go to the direct connection of the chain link. To do this, it is necessary to carry out the same operation, only in reverse order. We place the chain in the groove near the fixing bolt so that the protruding pin looks at the squeeze nose. Twisting the handle, smoothly push the pin back until it fully enters the link. After this procedure, the links into which the pin was pressed should move freely, if this does not happen, then you need to use the adjusting groove for the chain squeeze. Having placed the desired link in the adjusting groove, it is necessary to ensure that the ends of the pin protrude from both ends equally.

If the chain is from Shimano with a disposable connecting pin, press it into the link using a squeeze and break off the rounded end. This tip is needed to simplify the process of pressing the pin.

The most common and convenient type of locks. Fits on virtually all modern multi-speed bicycle chains. These locks are often difficult to remove. When I took off such a lock with my hands for the first time, I smashed my hands in blood, but the lock remained in place. Most often found on KMC, Sram, FSA chains. Surprisingly, Shimano doesn’t use such locks. Used for almost any number of speeds from 1 to 11.

Removing the chain from a bike

If the bike chain starts to make noise and it slows down, it will need to be repaired or replaced. To do this, the chain must be removed from the bike. to clean and replace worn links. The same procedure is required after installing sprockets with increased or decreased number of teeth. In this case, you need to add or remove links, respectively, which cannot be done without removing the chain from the bike. If this is done incorrectly, then subsequently problems will arise with the chain that will require its replacement.

  • – a set of keys;
  • – a device for squeezing the chain;
  • – screwdriver;
  • – pliers.

Remove the chain from the bike sprockets. To do this, turn it over, placing it on the handlebar and saddle. Then unscrew the rear wheel nuts holding it to the frame. Carefully free the chain from the rear sprocket or from the chain feed rollers on a multi-speed bike and remove the rear wheel. Next, release the chain from the front sprocket. It will be fixed on the frame, therefore, in order to remove it, you will need a special device for squeezing the chain.

Insert the selected link into the wringer and secure with the special knurled screw. This will secure the chain to the device. Fix the link so that the pin (chain peg) is exactly opposite the release axis of the device. After that, simply rotate the release shaft handle, which is attached to the bolt, and it will squeeze out the desired pin. Be sure to control this process so that it does not squeeze completely out of the outside of the link. If this happens, it will be very difficult to insert it back.

After squeezing out the pin, the chain will open on its own, remove it from the bike and perform the necessary operations. Be sure to make sure that the extruded pin is not lost. If it is necessary to shorten the chain, remove the required number of links using a chain breaker. In the event that you need to increase its length, insert the links. After that, assemble the chain directly on the frame, insert the rear wheel into the connectors, and pull the chain over the sprockets, and then fasten the wheel with nuts. After pedaling several times, make sure that the mechanism works without effort and does not create unnecessary noise.

There are bicycle chain options, one link of which is a lock. In this case, find such a link to remove the chain from the bike. Using a screwdriver, bend the locking plate and remove it with pliers, after which the chain will disconnect. But when choosing a new bike chain, be sure to keep in mind that this option is less durable and reliable.

Why is it necessary to change the chain?

It is recommended to change the bicycle chain every one and a half to two thousand kilometers, since it is subject to a lot of wear, and specifically, it stretches. This is not surprising, since a huge load falls on this part of the transmission, a large longitudinal force, which leads to the removal of the chain elements from each other, which entails a number of unpleasant consequences. This is, first of all, the slippage of the chain, which will occur when a large load is applied to the connecting rod. Thus, it will be quite difficult to develop high speed on a bicycle with a worn chain, and even about steep climbs you will have to forget about it.

The second unpleasant consequence of chain wear will be difficult gear shifting. When you try to throw the chain from one sprocket to another, it will jump off, not being able to rigidly fix on the teeth of the sprocket. Consequently, all the advantages of a bicycle with a large number of speeds come to naught.

If the listed problems are not so terrible for the everyday use of a cheap bike, then professional athletes and advanced amateurs lose most of the advantages of their expensive, sophisticated bicycles.

How to remove a chain from a bicycle for replacement?

When the old chain is physically and morally obsolete, not satisfying the bike owner with the operating conditions, it must be urgently replaced. As a replacement, a chain with the same number of links should be selected. However, its length should be slightly less.

How to remove the chain from the bike correctly? To do this, you need to use a special tool. squeeze. With the squeeze in place against either of the rollers, tighten the screw in such a way as to push the pin out. Next, you should loosen the tool, and then remove. In a similar way, using a squeeze, the chain is removed for regular scheduled cleaning.

Experienced cyclists often use special locks for quick maintenance, removal and cleaning of the old chain. The use of this device makes it possible to instantly remove it for replacement. However, some bike owners have biases about the effectiveness and reliability of the lock. Indeed, if it is present, the risk of a sudden break in the circuit increases. It is not known for certain how often the chains break in the presence of a lock, but nevertheless, without it, the mechanism looks more reliable.

Opening the bike chain lock

It’s not hard. Follow the algorithm.

At the same time, it is important not to break the clamp, since it will not be possible to connect everything back without it; Disengage the link. Now you can freely remove the bike chain and perform the necessary manipulations on it: shorten, clean or, if it is hopelessly damaged, throw it away

Now you can freely remove the bike chain and perform the necessary manipulations on it: shorten, clean or, if it is hopelessly damaged, throw it away.

To disconnect a solid structure, you will need a special tool called a squeeze. Using this device will allow you to remove the link without damaging it. The algorithm is as follows.

  • Select the link to be disassembled;
  • Place the bicycle chain in the position for pressing out and pressing in the link axle, or pin;
  • Tighten the screw and pull the axle towards you.
untangle, bicycle, chain, removing

You do not need to completely pull out the pin, as it will not be easy to insert it back into place. Manipulations with squeezing loosen the axis somewhat. Select another link to re-decouple. Press axle in reverse order.

  • Connect adjacent links together;
  • Press in the pin with the screw.

Determining chain wear

During the operation of the bicycle, all drive units wear out. chain, cassette and system (front sprocket block). But the wear of each unit has its own unique characteristics.

Chain. The chain usually lasts less than the cassette. about 4000 km (again, the resource strongly depends on the riding conditions). Chain wear is manifested by the fact that it “stretches”. That is, if you put a chain with an experience and a new one next to it, then with the same number of links, the old chain will be longer (of course, in a taut state).

Above. new chain. Below. the chain traveled 1600 km. It can be seen that the segments of the old chain are somewhat longer.

How To Untangle A Bicycle Chain

The stretching of the chain is not due to the physical lengthening of its plates, but to the wear of the axes of the links, that is, the chain seems to be loosening. But still, this leads to the fact that the distance between the links changes, and in the end there is a mismatch between the length of the chain link and the distance between the teeth of the sprocket. Therefore, a heavily worn chain begins to wear out the cassette and the system very quickly.

In the English-language literature, a simple way to determine the degree of chain wear is described. suitable for all models of mountain and road bikes (except perhaps completely antique)

untangle, bicycle, chain, removing

To determine wear, you need to measure the length of 24 chain segments. You can measure with a regular ruler or tape measure without removing the chain from the bike. In this case, measurements are taken on the upper half of the chain when it is slightly taut.

Since one segment of the chain is 1/2 “long, the length of the 24 segments should be 12”, or one foot, or if in Russian. 304.8 mm.

You can, of course, drive 10,000 km without doing anything with either the cassette, or the chain, or the system. But if you put a new chain on a worn out cassette, then problems will begin due to the different pitch of the chain and the cassette, and it will take some time for them to get used to each other. And a badly worn cassette will not work normally with a new chain, just as a badly worn chain will “eat up” a new cassette and system.

Therefore the first rule. if the drive is worn out badly, then we change everything at once. cassette, chain, system, not in parts.

There is an opinion that it is possible, without waiting for strong wear and tear, to purchase two or three chains, and change them in a circle, after 1000-1500 km. Then the chains and sprockets will wear out evenly.

On the other hand, different sprockets will wear out differently. Naturally, your favorite sprockets will wear out faster than the rest, so there is no need to talk about uniform wear in this case.

What to advise in each specific case? It depends on your riding style and intensity.

If you ride a bike only in the yard or park, and its mileage is measured in a couple of hundred kilometers per season, then obviously, you will not face wear and tear over the next ten years.

And for those who ride a lot and often, you can try changing chains in a circle.

How to remove a chain from a bicycle

Depending on the riding style, the question of removing the chain arises either almost immediately after the start of riding, for example, in a trial or downhill, or, after many kilometers of walks, when maintenance and replacement of the chain is required.

Loose chain tension on bicycles without gears

To eliminate the problem that has arisen, you need to understand why it has arisen and tighten the chain. This is done using special wrenches that every cyclist should have with them.

It is much easier to tighten the chain on a regular bike; in the case of a speed bike, it will be more difficult. For successful repair work, when the chain falls off the bike without speeds, you need:

  • turn the bike upside down.
  • If the rear wheel is attached with an eccentric, then you need to loosen it slightly, or not completely unscrew the nuts.
  • Adjust the desired chain slack.
  • Tighten the nuts.
  • Check chain tension and quality of work.

How to remove a chain with a lock

Each link in the chain consists of half-links. external and internal. They are interconnected by an axis (pin). A roller is put on the pin, which in turn comes into contact with the teeth of the sprockets.

How to remove a chain on a bicycle if it has a factory lock? This can be easily done in two ways.

Is the lock too tightly closed and does not lend itself? Take a thin wire or cable from the brakes, thread it between the links. Pull the edges of the wire sharply in different directions, the links will open and the lock will open.

Important points

  • Squeeze out the axle (pin) carefully so that it does not fall out, since pressing it back in is not an easy task. Without this you will not close the chain back.
  • Some squeezes have two seats: for pressing out-pressing the pin and for fine adjustment of it inside the bushing. In the case of an attempt to press out the pin with a seat for fine adjustment, you risk damaging the chain or tool.
  • Several times you have to open the same chain. choose different links, since after the first squeeze they loosen, as a result of which their strength decreases.

A quick example of how to remove a chain from a bicycle is waiting for you in the following video:

Lock on a chain

Many chains on modern bicycles are equipped with a lock. It allows you to open the circuit without tools. This can be done in the field, it will not take a lot of time and effort from you.

The lock allows you to open the circuit in any conditions

How to remove a chain from a bike: the easiest way

Why take it off? First, the chain wears out and needs to be changed periodically.

Secondly, without removing the chain, do not change the speed switches on the bike. And these are not all reasons to know how to remove the chain from the bike.

Thirdly, sometimes there is a need to shorten a chain that is too long. And, finally, fourthly, it is elementary to wash it. The latter can be done without removing it, but it will be more convenient and more effective with the chain removed.

Chain squeezing

If there is no lock, a special tool is needed. squeezing the chain. Course of action:

  • install the chain in the chain squeeze seat;
  • we rotate the squeeze screw, which gradually squeezes out the axle (pin) connecting the chain links to each other.

What tool is needed

We recommend purchasing a bicycle multitool. This is a very cool thing that any rider will need. A multitool can help out on a long trip. It includes a tool such as a chain wringer. It can be used to easily open the chain links.

By the way, the bike squeeze is sold not only as part of a multitool, but also separately. You will also need special pliers or pliers, a piece of wire, a thin cable from the brakes or a rope.

Removing the chain from a bike

You have become the owner of a bicycle and gradually understand the intricacies of its maintenance. Many things you can do yourself. replace the wheel, install a new speed switch, repair and clean some parts. Today we will show you how to remove a chain from a bicycle.

How to remove a chain without a lock

Now we will consider step by step how to use the bicycle squeezer correctly:

  • Select the link to be broken. The one from which the assembly of the chain at the factory began is the easiest. If you look closely, it is slightly different from the others. But you can choose absolutely any pin.
  • Have you chosen a link? Place its pin right in front of the release axle.
  • Slowly twist the knob to one side and gradually squeeze out the pin. Make sure that it does not pop out completely, you will not insert it back yourself. Also, do not lose the roller from the link.
  • Open the circuit, remove it, wash and lubricate.

If you have already disassembled the chain with a squeeze, do not break the same link. This will loosen it, and the mount will become fragile. Choose a new link every time.

Now you know how to remove the chain from a bicycle without a lock. As you can see, nothing complicated!

How to repair the chain yourself

The chain becomes wider and longer by increasing the distance between the parts. This is because the pins loosen with regular use. The chain must be replaced with a new one when it lengthens by 0.5%. If you do not have a special tape for measuring, use another method:

  • Place the chain on the drive sprocket and pull it away from the teeth.
  • Measure the distance you can pull the chain. If it is more than 4 teeth, it needs to be replaced or repaired.

What to do? Remove the chain and remove a few extra links so that it passes freely, but without sagging, over the large sprocket. You can remove extra links using squeeze. Only in this case the pins are squeezed out completely. Don’t overdo it and don’t take away too much.

How to install a chain on a bike

Getting the chain back onto a single speed bike is easy. Put it on the stars, screw the pin with a squeeze or snap the lock.

  • connect the links;
  • insert pin and roller;
  • place the pin opposite the squeeze by turning the screw and push it back.

The chain on a multi-speed bike is attached as follows:

  • fix switches to small stars;
  • put the chain on the stars, taking into account the location of the tension rollers;
  • align the links, clamp the chain and press in the pin with the bale wringer or close the lock;
  • check chain travel by pedaling several times.

If the slack is removed, the pedals move easily and won’t lock. everything is fine! You shortened the chain yourself and installed it well.

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.

Disadvantages of using

Like any other bike part, the lock has its drawbacks. And the most important, perhaps, is strength. Since it can be disassembled in two, it automatically becomes less reliable than conventional chain links. This raises the risk that the chain is likely to break exactly where it is installed. But do not worry about this, because this happens extremely rarely and after long-term use.

Of course, a chain lock is a very handy thing. With it, you can easily disassemble and assemble the chain so that you can easily remove it from the bike and then install it. If you install a new copy, then it will last much longer and will not be life-threatening. That is, having installed a new one, you can not be afraid that it will burst at the most inopportune moment. Also, do not forget about the sizes that are suitable for this or that option. In some cases, the same spare part may be suitable for different sizes.

How to determine the degree of chain wear?

After making sure of the need to periodically change the circuit, you should proceed to explaining the process itself. First of all, you should learn how to determine the moment when the chain requires replacement, because it is difficult to systematically monitor the mileage. The most accurate way to determine the degree of wear is to measure the distance from the center of an arbitrary pin (the axis connecting the links) to the center of the twenty-fourth pin after it with a simple ruler. This distance should be 304.8-306.4 mm. If the measured distance is longer than the recommended one. chain needs replacement.

Fitting the chain to the bike

To put the chain on the singlespeed, it is enough to hang it on both stars, press in the pin or click the lock. With high-speed bikes it will be a little more difficult:

  • Fix switches to small stars.
  • With regard to the location of the tensioning rollers, put the chain on the stars.
  • Combine links.
  • Clamp the chain and press in the axle. If the bike chain is with a lock, we do without squeezing.

After the installation is completed, it is necessary to check the course of the chain: rotate the pedals several times. If no sagging or obstruction is observed during twisting, then the chain is of the optimal length and is installed correctly.

Every owner of a two-wheeled horse will be able to cope with the removal and installation of a bicycle chain. An uncomplicated and simple procedure will not take much time, but it will perfectly help on further trips!

How To Untangle A Bike Chain

How to use?

Before proceeding with the installation of the lock, you need to check if there is already another lock on it, which came directly with the kit when buying a bicycle. Finding a lock is usually easy, since the name of the manufacturer will be stamped on it. Whether to install it or not is everyone’s choice. But if there is a need to often remove the links, then the lock in this case will be useful. To install the lock, half of the link must be removed to make room for it. In order to accurately do this and not damage the links, you must use a tool called a squeeze. The removed pair of outer links can be thrown away and replaced with lock plates. After the performed operation, it is necessary to fasten the lock. To do this, you need to stretch the chain until a click appears. If you suddenly need to remove this spare part, then it will be enough to bend the chain and slide the hole until it opens.

It should also be noted that not every lock will be easy to push apart by hand, so additional force and the appropriate tool may be required to remove it. For safety reasons, do not install the lock from an old chain. It will be better if this detail is individual for each vehicle, because at the most inopportune moment it can fail, because was sharpened to fit the previous chain.

How to put a lock on a bicycle chain

A bicycle chain lock is needed to quickly lock and disconnect bicycle links. Externally, it is a quick disconnect link that consists of two plates. Before buying, you need to familiarize yourself with the information that is given on the packaging. in the future it will facilitate the process of installing and removing the device. As a rule, it also contains an indication of how many speeds are acceptable for the application of a particular model.

It happens that the lock is already present in the biker’s arsenal: it was included with the bike and was put on when buying. It will not be difficult to find it. the brand name is always stamped on it. But if there is no device, and you often have to remove the chain links, then installing a bicycle chain lock, the price of which is quite affordable, is really worth it. To begin with, you need to remove half of the link of the bicycle chain to make room for the device. It will be possible to do this correctly with the help of a squeeze. such a tool will allow you to perform an operation without damaging the links.

Removed external elements must be replaced with lock plates. After that, the lock needs to be fixed. For this purpose, the chain belt is stretched until it clicks. The reverse operation can be done by bending it and sliding the hole until it opens. However, not every lock can be pulled apart without the use of an appropriate tool and additional efforts. It is important to remember that for safety reasons:

What is this part?

These are quick-release links consisting of two plates. Thanks to its design, it becomes much easier to open and close the links of the bike. When purchasing a lock, you should pay attention to what is written on the packaging. As a rule, it contains the most important information that will help in the further use of the castle. Particular attention must be paid to how many speeds this lock is suitable for. Most likely, more than one indicator will be indicated there, which is beneficial for users.
