How to remove a chain from a bicycle with a squeezer. How to properly remove a chain from a bicycle. Bicycle chain parts and necessary tools

After using a bicycle for a long time without maintenance, the chain often begins to sag. How to shorten a bicycle chain at home? What is required to determine the correct length? We will look for answers to these and other questions in the presented material.

What factors affect the elongation of a bicycle chain?

A number of factors lead to wear of the axles, the so-called pins, of a bicycle chain. Firstly, deposits in the form of old oil accumulate between structural elements, onto which dust and small contaminants stick. Additionally, stretching can put undue stress on the chain when cycling up steep inclines. Another reason is the end of the chain’s service life, the destruction of its elements as a result of impacts and metal corrosion. To avoid discomfort while operating the bike, you need to understand

How to determine the optimal length?

Before you figure out whether you can shorten the chain on a bicycle with your own hands, you need to find out how long it should be for comfortable movement. To understand this issue, it is enough to throw the chain onto the largest sprockets in both the rear and front chassis of the bike. Next, you need to open one of the links. Finally, tighten the chain as much as possible. It is enough to add a couple of centimeters to the resulting length so that the chain is not subject to excessive stress while driving.

Preparation for dismantling

To make it easier to work with the chain, it is worth cleaning it first. The simplest way is to wipe it with a regular piece of material soaked in kerosene. You can also use a special remover, in particular AB-80 or WD-40 liquid.

Tools

How to shorten the chain on a speed bike or mountain bike? There are several tools you can use to separate the links. First of all, you should pay attention to the special squeeze. The latter is a simple device that resembles a manual stand with a rod that applies pressure to the axes (pins) of the links. You can buy such a tool at any point that sells sports equipment. Its purchase will cost from 500 to 1000 rubles.

If it is not possible to buy a squeeze, then you will have to use improvised means. We are talking here about a hammer and a metal rod, which will serve as a punch for removing the axes of the links. You will also need a couple of nuts that will fit under the chain links.

How to shorten a bicycle chain using a wringer?

To do the job using a special tool, you need to perform the following sequence of actions:

  1. Place the squeezer in a position where its rod is centered on the axis of the chain link.
  2. Perform rotational movements with the tool until the axle is almost completely out of the link.
  3. Disconnect the circuit and, if necessary, perform similar operations with its remaining sections.
  4. Remove unnecessary links and connect the structure.

Having figured out how to shorten a chain on a bicycle, you need to figure out how to connect it. A narrow half-link must be inserted between the cheeks of a wide one. The axle should then fit completely into the hub hole. Next, it is necessary to evaluate the mobility of the links. If it is insufficient at the joint, the hinge can be developed using pliers.

How to shorten a chain on a bicycle without squeezing?

The absence of a specialized tool designed to separate chain links is not a critical point. As mentioned above, an alternative to squeezing can be a metal pin, nail, etc. Also here you will need a hammer, with which the axles will be knocked out of the links.

With this approach to business, the main thing is to be careful. After all, inaccurate, too strong blows can lead to deformation of the link plates. To prevent this from happening, regular nuts must be placed under the chain elements in advance.

Those who are trying to shorten a bicycle chain for the first time without using a special squeezer are recommended to practice beforehand. For these purposes, it is worth using an old chain or separate, unnecessary links. This kind of work requires some skill. Therefore, before influencing a working chain with a hammer and a punch, you need to perform the above steps several times and evaluate the result of your own work.

Finally

So we figured out how to shorten a bicycle chain. As you can see, you can cope with such a task not only with the help of a special squeeze. To get the job done, sometimes it is enough to use available tools that can be found in every home.

Removing a chain from a bicycle is a familiar procedure for experienced cyclists. It is carried out periodically, using a special tool. Most often, the reason for dismantling is the need to replace an element. On a bicycle chain, the price is at an affordable level, and therefore such a purchase is not expensive.

Options with and without a lock: action algorithms

In addition to the situation when wear of a part precludes repair and only a complete replacement is possible, there are other reasons to remove the chain. Among them:

  • lengthening or shortening (with the addition or removal of teeth);
  • the need to boil the product in solid oil;
  • the need to wash, lubricate, clean, etc.

On modern models of bicycle machines, two types of chains are installed - without a lock and with one. Traditionally, it is customary to remove the chain from the bike using a special device - a squeezer. It is able to cope even with an integral part of the structure. Such bicycle chains in Moscow can be purchased online on specialized resource websites. To remove those with a lock, squeezing is absolutely not necessary.

It is easy to determine the presence or absence of a lock by visual inspection. This is a link that is different from the rest. It is disconnected by moving the pins on each of the links, using pliers or simply with your hands. The part must be connected in the reverse order.

The case where there is no lock seems more complicated. If you decide to buy a chain for a bicycle without it, then at the same time it is worth purchasing a squeezer, which would greatly facilitate the removal procedure. But if it is missing, this will have to be done with improvised tools, adhering to a certain scheme:

  • ordinary vices are screwed to the surface;
  • fix the chain with a nut as a backing on one side so that the hole coincides with the pin;
  • a small screw with a head is attached to the other side;
  • squeezing the vice, squeeze the pin using a ball into the hole from the nut.

Freeing one side is not enough to open the circuit. You must move the link to remove it, or continue manipulation using an additional ball.

Is squeezing necessary?

Having purchased a one-piece chain for a bicycle in an online store, it is worth keeping in mind that the chain squeezer will be indispensable on the road in the event of force majeure. You can solve the problem without it, but it is better to be prepared for unpleasant surprises. In addition, using a special tool is much easier to carry out work than manually.

Keeping a bicycle chain in perfect condition guarantees an adequate response to the cyclist’s actions from the entire mechanism while driving. When purchasing a new vehicle, there is no need to separately purchase a new chain and install it. However, in the future you will still have to learn how to remove the chain from the bicycle for maintenance or replacement.

When should you change your bicycle chain?

A good bicycle chain lubrication can significantly increase the service life of the entire system responsible for movement. At the same time, you need to be able to notice the moments when it begins to need maintenance or repair.

Excessive wear on a bicycle chain not only causes constant discomfort while riding, but also causes active deformation of the chainrings. If a worn chain is left unattended for a long period of time, it is guaranteed to lead to the need to replace a whole set of expensive mechanisms.

In order to assess its condition as objectively as possible, it is necessary to look not at the mileage, but first of all to measure the length of all its links. The chain length in normal condition is approximately 305 mm. The reason for its replacement is its stretching to 308 mm or more.

How to deal with chain stretching?

A common problem with a bicycle chain is its sagging. The reason for the development of this process is the gradual wear of the links. Moreover, it is almost impossible to prevent wear of individual chain elements. The problem can be eliminated only by removing excess links as they stretch.

To correctly perform the necessary actions, you must:

  • Decide how to remove the chain from the bicycle by first disconnecting the rear wheel.
  • Disconnect the chain using pliers.
  • Determine the number of unnecessary links.
  • Remove unnecessary elements.
  • Connect the links, install the chain, check its mobility and functionality.

How to remove a chain from a bicycle to replace it?

When an old chain becomes physically and morally obsolete and does not satisfy the bicycle owner with operating conditions, it must be urgently changed. As a replacement, select a chain with the same number of links. However, its length should be somewhat shorter.

How to remove a chain from a bicycle correctly? To do this, you need to use a special tool - a squeeze. Having placed the squeeze opposite any of the rollers, you need to tighten the screw so that this leads to the pin being squeezed out. Next, you should loosen the tool and then remove it. In a similar way, using a squeezer, the chain is removed for regular scheduled cleaning.

Quite often, experienced cyclists 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 bicycle owners have prejudices regarding the effectiveness and reliability of using a lock. After all, if it is present, the risk of a sudden break in the chain increases. It is not known for certain how often chains break when there is a lock, but without it the mechanism still looks more reliable.

How to tension a chain on a bicycle?

Managing chain tension on standard road bikes is quite easy. It is enough to pull it back towards the fork. The main thing is to perform such a manipulation carefully so as not to overdo it by applying too tight a tension.

However, both a strongly and weakly tensioned chain can create some discomfort while driving. So, when trying to figure out how to tighten a chain on a bicycle, it is important to stop in time so that it is in a state of medium tension.

Bicycle chain tensioners

A special bicycle chain tensioner can be an effective and useful accessory, the use of which allows you to maintain the necessary chain tension while riding. This accessory is used mainly by fans of extreme, aggressive driving.

Chain tensioners are usually installed on single-speed bicycle models. Such accessories consist of one or more rollers, a lever and a spring. Tensioners work on the principle of systematically pulling the bicycle chain in the required direction, which creates the required tension. Moreover, the presence of a tensioner prevents the chain from falling from the drive sprocket located on the bushing.

Experienced cyclists are advised to always have several chains in stock. Each of them should be operated with a rolling distance of no more than 600 km. After which the bicycle chain is replaced. A new, shortest one is put in its place. As a result, the life of not only all existing chains, but also the transmission of the two-wheeled vehicle is significantly extended.

The chain is a key element of the transmission unit of a bicycle. Consistently passing through the teeth of the drive stars, it transmits torque to the rear wheel, thanks to which the bicycle moves. During movement, the chain mechanism is subjected to dynamic loads, which eventually leads to its wear.

On singlespeed, as a rule, the chain is designed for its entire service life: when moving along the stars, it runs smoothly and straight, without deviations. The situation is more complicated with chains on multi-speed bicycles: there is no right angle between the front and rear sprockets, which is why it is always located at an angle relative to the frame. The impact on the chain mechanism increases several times compared to parallel transmission, which leads to periodic wear. To avoid damage to the entire transmission unit caused by chain wear, it must be replaced in a timely manner.

Not only “high-speed” chains require removal; quite often they are also removed from single-speed bikes for periodic repairs or cleaning. We will tell you how to remove a chain from a bicycle and put it back in this article.

Symptoms of a problem

First of all, you should pay attention to chain malfunctions on multi-speed bikes. Traditionally, riding time is determined by mileage, but these values ​​are too approximate, because everything depends on the conditions of cycling: the quality of the roads, the selection of gears, speed, the load on the pedals and, accordingly, on the front sprockets.

The first signs of a bicycle chain failure are inaccurate gear shifting and suspicious sounds (provided that the chain has not lost its lubrication). The following method will certainly help you determine the malfunction: bend it away from the largest sprocket and look at the number of free teeth. If the chain moves freely from three or more teeth, replacement is required urgently. Two teeth “warn” that wear is just around the corner, but you can still ride.

Using the same method, you can see if the chain is loose on a single-speed bicycle: bend it away from the front sprocket and look at the number of teeth.

Determination of the degree of attenuation

Another way to determine wear is to measure the length:

  • 304.8 mm is the optimal chain length.
  • 306.5 – 307.5 – average wear, suitability for repair. You can still drive.
  • 308 mm – high degree of wear of both chain and sprockets.
  • More than 308 mm – damage to the entire transmission.

Measuring elongation requires removing the chain completely from the bike.

Lock and solid chains

The locking chain is equipped with a special clamping device. It is not difficult to unhook and put it on - you just need to disconnect the lock. To find it, carefully examine the chain on both sides and find a split link. In principle, it will not be difficult to find it on a clean chain: there is a plier on top that fixes the link and does not allow it to move apart. Also, the manufacturer's inscription is usually stamped on the lock link. If you can’t find the lock for a long time, then either the chain is dirty, or it is lockless, or solid.

Bicycle chain with lock

You can’t just disconnect a bicycle chain without a lock: all the links on it look the same, however, they are also interlocked. This causes great inconvenience during cleaning; for example, it is necessary to carry out “general cleaning” in a solvent. In the case of the keyhole, everything is simple - steal it and put it in kerosene. A solid bicycle chain, even removed from the sprockets, will remain hanging on the frame.

In terms of removal, a chain with a lock is certainly more convenient than its counterpart. However, for some reason the fastening may become loose: the pincer may fly off, and the link itself may come loose. Bicycle chains without locks do not have such weak points, and if it breaks, then the matter is solely in its quality.

Opening the lock and squeezing the link axis

Opening the lock is quite simple: use a screwdriver or other object (for example, a knitting needle) to pry up the pincer clamp. The main thing here is not to damage it, and even better, not to lose it, otherwise you won’t be able to fix the chain later. Next, we uncouple 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.


Lock in disassembled condition

You can disconnect a continuous chain only with a special tool - a squeezer. With its help, you can easily disassemble the link without damage. The procedure is simple, but there is no need to rush:

  • First, select a link for disassembly.
  • We insert the chain into the position of pressing out and pressing in the pin (link axis).
  • We tighten the screw with a handle and pull out the axle. The direction of extrusion is towards the squeeze screw, that is, towards yourself.

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



Hall chain release device

Squeezing loosens the axle a little, so when disengaging again, you should select a different link.
Pressing the axle into a link is carried out in the opposite order: connect adjacent links and press the pin with a screw.

Elimination of defects

A common type of wear is sagging of the chain when its length increases relative to the original. Previously, critical values ​​of the length of a bicycle chain were considered at which it cannot be used. Everything is true, but the chain does not have to be thrown away immediately, but can be repaired. Under prolonged loads, the axles become loose, which causes longitudinal and transverse expansion. It is impossible to eliminate the transverse one, but it is quite possible to tinker with the longitudinal one.

The extra links must be removed in such a way that the chain runs smoothly and without tension along the large sprocket. Using a squeezer, excess links are removed, and the axle shafts are completely pulled out from the elements being removed. The main thing here is not to make a mistake and not pull out too many links.

If you have to drive with a stretched chain, then in order to prevent it from falling off, you can install so-called parts that prevent the chain from flying off when driving. There are several types of such devices:

  • Roller with two locks.
  • With wide casters.
  • Frame (or rollerless).



This is what dampers look like on a bike

Using dampers as protection is, of course, good, but it would be better to think about changing the chain.

Installing a chain on a bicycle

To install a chain on a singlespeed, you just need to hang it on both sprockets, press in a pin or snap the lock. With high-speed bikes it will be a little more difficult:

  • Fix the derailleurs on the small chainrings.
  • Taking into account the location of the tension rollers, put the chain on the sprockets.
  • Combine the links.
  • Clamp the chain and press in the axle. If the bicycle chain has a lock, we do without squeezing it.

After the installation is completed, you need to check the chain movement: spin the pedals several times. If there is no sagging or difficulty during torsion, then the chain has the optimal length and is installed correctly.

Every owner of a two-wheeled horse can cope with the removal and installation of a bicycle chain. A simple and simple procedure will not take much time, but it will be a great help on future trips!

If you ride a bicycle for many kilometers, the spare parts will sooner or later wear out. After a long mileage, the bicycle chain will “stretch” and will need to be replaced.
Technically the chain does not stretch, but the pins that connect the links wear out, increasing the length of the chain.

Stretched chain accelerates wear on the cassette and chain rings on the sprocket, so getting a new chain when the stretching is already noticeable is a good idea. It is recommended to replace the chain every 1000-1500 kilometers. By the way, replacing a chain is much cheaper than replacing cassettes or chain rings on a sprocket.

The chain repair and shortening information below will be very helpful.

Bicycle chain parts and necessary tools

Chain wear indicator: A typical chain wear indicator hooks onto a pin in the chain while the other end is inserted between two pins or rollers. The numbers on the tool will show how worn the chain is and whether it is time to change it.

New chain: The type of chain depends on the number of speeds of the bike. So, for example, if the bike is 9-speed, you need to buy a 9-speed chain. More advanced chains include a special coating that will delay the appearance of rust, or they are already made of stainless steel.

Replacing pins or connecting link: New chains immediately come with a new pin or special link called a connecting link that connects the 2 ends of the chain together.

If you are repairing an existing chain, you will need to buy replacement pins or connecting links separately - they must be compatible with the chain speed and brand.

Squeeze: If you have a standard link chain, you will need a compatible puller that will allow you to easily remove the old pin and install the new one when disconnecting and joining the chain.

Pliers: If you have a chain that connects to a connecting link, you will need pliers to make the process of disconnecting and connecting the connecting link easier.

How to check a bicycle chain


To check the chain for significant stretch, use. Hook one end onto a roller or pin in the chain. The other end will either go to the drive wheel itself, or you can place it in the gap between the two rollers. If it falls out of this gap, the chain is so stretched that it needs to be replaced.

The chain wear indicator has numbers that indicate how worn the chain is. A value between 0.5 and 0.75 indicates that the chain needs to be replaced. A value of 0.75 or higher means that it is necessary not only to replace it, but also to check the condition of the cassette and drive sprockets, since stretching the chain could cause significant damage to the cassette and drive sprockets.

You can check the chain in another way - measure the chain with a ruler or tape measure. On an unworn or new chain, 12 full links (measured from pin to pin) should equal 12 inches (30.48 cm). If the 12 links are 31 cm or longer in length, the chain needs to be replaced.

How to remove a chain from a bicycle

To remove the chain from the bicycle, you will need to disconnect it (break it). There are several ways to do this, depending on whether the chain has a connecting link or not.

Before you begin, move the chain to the smallest sprocket and smallest cog.

It will be even better if you remove the chain from the front sprocket or remove the rear wheel from the bike. Both of these methods will remove tension from the chain.

If you have a standard chain without a connecting link: Install the squeezer so that the squeezer pin aligns with the pin in the chain. Turn the release handle until you pull the pin out far enough to break the chain.

If you have a chain with a connecting link: To find a connecting link, look for a link that is noticeably different from the others.

This is the place where you can break the chain.

The connecting link has a pin on one side inserted into a notch on the other side.

Using pliers, squeeze the connecting link on both sides until it opens.

How to determine the length of the new chain?

Usually the new chain is too long, so it will have to be shortened by removing links. There are several ways to do this. The easiest and best way to determine the length of a new chain– attach it to the old chain. Then you just need to shorten it to match the old one (to be sure, you should count the number of links).

Another variant. Thread the chain through the front derailer and drape it over the large sprocket at the front and over the large cog at the rear. Do not run the chain through the rear derailleur yet. Connect the two ends of the chain tightly. If the chain connects and there are still 2 whole links left on the overlap (the half of the link will still remain at the end - the place where you connect the chain), the chain length is correct.

Note: Many full suspension mountain bikes use a design that moves the rear axle further away from the bottom bracket while the bike is riding, through the suspension; it is called " chain growth" To accommodate the chain growth, you will need to compress the rear suspension a lot when using the method above.

Before removing unnecessary links, make sure that the two ends of the chain will connect. A chain can only connect if the outside of the link connects to the inside of the connecting link. Then disconnect the remaining links.

Bicycle Chain Installation

It's time to thread the chain through the rear derailleur and connect it. Pay attention and make sure the chain fits exactly through the drive wheel on the rear derailleur.

Using pins: If the chain does not have a connecting link, then use a squeezer to connect the chain to the pin that is already in the new chain.
If you are repairing an old chain, always use a new pin instead of the old one. The new pin must be compatible with the chain, its speed and brand. The new pin must be inserted halfway using a squeezer, then pulled out on the other side using pliers.

Using connecting links: If you are connecting a chain with a connecting link, place each half of it on each end of the chain, connect the ends of the chain, assemble the connecting link with a tool to put it in place.

It is also possible to connect the connecting link without tools. Connect it and pull the chain in different directions to lock the connecting link as much as possible. Then loosen the derailer clutch, if equipped, and rotate the pedals so that the connecting link is at the top of the drive chain. Using the brakes, step firmly on one pedal, tension will be applied to the chain and it will snap into place.

How to replace a chain on a bicycle - video

It happens that you need to remove a bicycle chain - for example, to clean it, replace it or adjust the length (the latter is done if your new cassette has a different number of teeth, and you need to change the length of the chain accordingly by adding or removing a certain number of links) .

How to remove a chain with a lock

Inspect the chain: if you find a link that is different from all the others, then you are lucky - you have a chain with a lock. In order to separate it, move the pins (pins, axles) on each half-link (cheek). The circuit will open. The whole operation will take literally a minute. You don't need any special equipment: if you suddenly can't move the pins by hand, use pliers. Assembly is also done without any tricks, in reverse order.

How to remove a chain without a lock

If you have a chain without a lock, then you will need a special tool - a chain squeezer. It is inexpensive and takes up little space, so we recommend that you always carry it with you, along with a set of hexagons and a repair kit for cameras. Anything can happen on the road - if the chain suddenly breaks, you can easily remove the damaged links using a squeezer and connect the chain again.


How to remove a chain without squeezing? And is it worth doing?

How to remove a chain without squeezing is a pressing question. But no matter how often it is asked, it is better to remember one life rule. For good repair and maintenance, it is better to use a specialized tool! In this case it is chain squeezing.

There are two types of squeezers, most have two seats. One of them is for assembling and disassembling the chain, the second is for adjusting the position of the axle in the chain link bushing. If your squeeze is just like this, with two seats, then insert the chain link so that it is on the side closest to the adjusting screw. If you place the chain in the wrong place, you may accidentally break off the partitions between the squeeze seats during operation or crush the cheeks of the link.


Let's assume that the chain was laid correctly. Now carefully rotate the handle. You may have to apply significant force, so try to work carefully so that the link in the squeezer does not become distorted, otherwise it may be damaged. Make sure that the tip of the squeezer presses exactly on the pin. There is no need to turn the screw quickly; you should stop at the moment when the pin is squeezed out of the entire link, but remains on the far cheek. If you push it all the way out, believe me, it will be very difficult for you to put it back in. Also be careful not to accidentally knock the pin out of the cheek: this could cause it to roll away in an unknown direction and get lost.

When assembling, you will not need anything other than the same squeeze. I remind you again: be careful, don’t get carried away, so as not to squeeze the pin out of the link.

Two important notes:

  • If your chain is equipped with a lock, you should not disassemble it by squeezing it.
  • If you have to disassemble the same chain many times, then choose a new link each time: if you squeeze out the same pin over and over again, this will deteriorate the strength of the chain

After using a bicycle for a long time without maintenance, the chain often begins to sag. How to shorten a bicycle chain at home? What is required to determine the correct length? We will look for answers to these and other questions in the presented material.

What factors affect the elongation of a bicycle chain?

A number of factors lead to wear of the axles, the so-called pins, of a bicycle chain. Firstly, deposits in the form of old oil accumulate between structural elements, onto which dust and small contaminants stick. Additionally, stretching can put undue stress on the chain when cycling up steep inclines. Another reason is the end of the chain’s service life, the destruction of its elements as a result of impacts and metal corrosion.

How to determine the optimal length?


Before you figure out whether you can shorten the chain on a bicycle with your own hands, you need to find out how long it should be for comfortable movement. To understand this issue, it is enough to throw the chain onto the largest sprockets in both the rear and front chassis of the bike. Next, you need to open one of the links. Finally, tighten the chain as much as possible. It is enough to add a couple of centimeters to the resulting length so that the chain is not subject to excessive stress while driving.

Preparation for dismantling

To make it easier to work with the chain, it is worth cleaning it first. The simplest way is to wipe it with a regular piece of material soaked in kerosene. You can also use a special remover, in particular AB-80 or WD-40 liquid.

So we figured out how to shorten a bicycle chain. As you can see, you can cope with such a task not only with the help of a special squeeze. To get the job done, sometimes it is enough to use available tools that can be found in every home.

What could be better than a day spent cycling in the countryside! However, the pleasure can be overshadowed by an unexpected chain breakdown. If domestic bicycles mostly consist of detachable chain sections, the locks between which can be separated without much difficulty, then the chains are often one-piece. Today we will talk about how to remove the chain and what devices exist for this.

When is the chain removed from a bicycle?

Experienced cyclists remove the chain regularly. For example, in the case when replacing the system or just the cassette entails a change in the number of teeth, the chain will have to be shortened by removing teeth, or lengthened by adding additional ones. In addition, the chain is removed in order to:

  • wash;
  • boil in grease;
  • replace (if repair is no longer possible).

Instructions for replacing a chain with a squeezer yourself


Removing the chain by squeezing.

Usually, to remove the chain from the bike, an auxiliary tool is used - a squeezer. It makes it easy to remove even a permanent chain. The sequence of work is as follows:

  1. Decide on the section of the chain to be disassembled. In case of repeated disassembly of the chain, it is preferable to take a section of the chain that cannot be repaired.
  2. Insert the chain into the squeeze so that the pin is opposite the clamping axis.
  3. Secure the chain with a knurled screw.
  4. Turn the handle, squeezing the pin out.
  5. Remove unnecessary links using a squeezer, pressing out the entire pin.
  6. Connect the chain links. In this case, the pin located in the cheek should look outward towards you. First you need to run the chain through the rear and front derailleurs. Then place the chain links one on top of the other so that the pin aligns with the bushing.
  7. Unclench the “cheeks” with pliers. Once the ends of the chain are in place, the pin coming out will prevent the links from coming apart.
  8. Insert the squeeze into the link so that the axes of the pin and rod match perfectly, and rotate the funnel, pressing the pin into the hole.
  9. Check the symmetry of the position of the pin and the “cheeks” of the links. Adjust their position if necessary.
  10. Check the links for mobility relative to each other. If necessary, increase the mobility with pliers.

Important! On a high-speed bicycle, the chain is installed along the switch rollers at the rear in accordance with the pulling diagram. To be able to replace the chain multiple times in the future, it is best to lock the chain.

Sequence of actions for removing a chain from a bicycle without squeezing it yourself

The squeezer is a useful device. However, it is not always at hand. What to do then? The prospect of being left in the middle of pristine nature somewhere many kilometers from the city does not look attractive. You can remove the chain from the bike without squeezing it. Doing this on your own will not be easy, but it is quite possible. Let us consider in detail the options for disassembling a chain with and without a lock.

Model with lock


How to check if a chain has a lock? As easy as pie! A quick inspection to see if the chain has a link that is different from its neighbors. This is the castle. You can disconnect it by moving the pins on each of the links with your hands or pliers. To assemble the chain, you need to do the same steps in reverse order.

Model without lock

In this case, it will be difficult without squeezing. And the result will be unpredictable. But, if there are no other options, choose the lesser of 2 evils. So, we remove the chain without a lock from the bicycle using improvised means in this order.

  1. Screw an ordinary vice to the table.
  2. Secure the chain in a vice by placing a nut on one side, the hole of which corresponds to the pin.
  3. Attach a small screw with a head on the other side.
  4. While holding the vise, push the pin into the nut hole with the ball.

Important! In order to open the circuit, freeing one side is not enough. You need to move the link and remove the chain or add another ball and continue trying.

Summing up, we can confidently say that the squeeze is an indispensable thing on the road for every cyclist. And if a broken chain with a lock can still be removed from the bicycle without this device, then as for a chain without a lock, it will be difficult to do without it. However, in case of form major circumstances, you can use the instructions given above.

Biking is one of the most enjoyable modes of transportation that will help you reach your desired destination. This can save you money and time. And the most important and important thing is that it is very good for maintaining your health.
A hassle-free ride can always give you pleasure, but problems like your bike chain falling off again and again can also ruin your lovely journey.

A bicycle chain is a wonderfully efficient means of transmitting mechanical energy from one place to another. Typically, bicycle chains are made of plain carbon or alloy steel, and the links are connected by several pins. Thanks to good engineering, modern materials and regular maintenance, it is extremely efficient with minimal loss of system power. A chain doesn't break often, but when it does, it can end your ride if you don't know how to fix it.

Chain manufacturers try to make all their links equally strong, but a chain is only as strong as its weakest part. The problem is that chains often have around 400 moving parts. Securing a bicycle chain is a routine task that you should be able to complete within a few minutes, whether on the road or in the garage.

The circuits are more complex than one might expect. With up to 116 links in a standard bicycle chain, it has more moving parts than any other bicycle component. Chains rarely break straight. Energy is evenly distributed, even under load.

It is known that chains often wear out and stretch over time. It needs to be replaced as soon as possible. Before attempting to remove the chain while it is on the bike, move it to the smallest sprocket at the back and front. The process of removing a bicycle chain in most cases requires the use of a chain tool, which is sure to push the pin out of the bicycle chain.

How to remove a bicycle chain

Bicycle chains are an integral part of your bike's performance. They help transfer energy from your pedals to turn your wheels. There are times when you need to remove the chain from your bike: for cleaning, to remove a chain link, for re-lubrication, or to replace an old chain with a new one.

Step 1.
Place the chain in the tool and align the tip of the tool with one of the pins that hold the chain links together. These pins will be the same diameter and you will use the pin on the tool to remove the pin in the chain.

Step 2.
Turn the screw on the extraction tool to remove the pin from the connector. This will happen slowly but steadily - watch the pin of the tool to make sure it is pressing on the pin and not the link.

Step 3.
Pull the pin out of the chain. If you have trouble, use the tool to push it out completely.

Step 4.
Remove the tool pin from the chain after releasing the chain pin. The chain will disintegrate and you will be able to remove it from the gear teeth.

If you have a broken chain, simply remove the derailleur rollers if it hasn't already fallen to the ground. It can get stuck, scrape and get stuck between the gears. If so, carefully pull it out, focusing on where it is actually stuck. Don't resort to pulling it out with tools. And be very careful not to bend anything. If you can't pull it out, then take a wheel from your bike, which will relieve some pressure on the gears. If this still doesn't work, you can remove the links using tools, and then you should be able to remove the chain easily.

Using the Retainer

It's a good idea to place a chain lock on your chain before removing it from your bike. The chain holder is nothing more than a short length of wire (about 5cm) with two 90 degree bends on either end. Connect the bent ends of the chain. This way, when you break the chain, the detent will prevent the derailleur from shifting back when the pressure is released. When reinstalling the chain, use the clamp. You can also simply knock the chain off the front chainrings so that it rests on the frame on the inside. This also relieves tension from the circuit.

Remove and replace chain

Complete the removal of the bicycle chain by unscrewing the drive pin and removing the chain tool from the chain. Hold both ends with your hands and remove the locking device, releasing tension from the switch. The chain will hook onto the shifter and disengage the gear.
If you are reinstalling the same circuit using the original pin or connector pin. It will be a little difficult, but doable. Thread it back through the derailleur, use a clamp, or have someone hold both ends to connect the two ends.

The following steps will help you repair a damaged chain while riding.

Step 1: Stop and assess the damage.
If you have a problem with your bike chain, stop riding and turn your bike cover over. This will make it easier to assess the damage and secure the chain. Turn the bike over so it rests on the seats and position it carefully to prevent chafing.

Step 2: Use the chain switch tool.
At home, you can easily repair a chain using a hammer or pliers, but a chain tool is the only option outside, so you all need a chain tool to fix your broken chain.

The first thing to do is to remove the entire chain using a chain shifter tool if the chain is still attached to the bike.

Step 3: Use lubricant.

After removing the broken chain, it is better to clean it with degreaser and water, so that the link chains can move easily and prevent the chain from being fixed in a short time.

Step 4: Inspect the links.
Now, take a close look at the broken part of your chain to identify the damaged part. And use the breaking tool to pull the pin out of the broken chain. Each link has two pins, round in shape and attached to the other links. Keep an eye out for broken links that are connected to the rest of the chain.

Step 5: Return the chain to the bike.
Now you need to get a chain on your bike which will make things easier for you. Now fit the two ends of the chain into each other so that the holes line up and the pin remains on the outside so you can push it out from all sides to complete the chain.

Step 6: Use the tools.
Use the chain breaker again to screw the pin in and push it down. Twist it back and forth until it is loose enough to bend around the gears.

Step 7: Lubricate the chain.
Lubricate your chain with bicycle lube to keep your bike running as well as before. Now you can reuse your bike and complete your journey.
