How to remove a bicycle chain without a puller

The sequence of actions for removing the chain from the bicycle without squeezing with your own hands

Pomace is a useful tool. However, it is not always at hand. What then is to be done? The prospect of staying with a non-working bike 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 will not be easy to do it yourself, but it is quite possible. Let’s consider in detail the options for parsing the chain with and without a lock.

When is the chain removed from the bike??

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

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

Model with a lock

How to check if the 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 sliding the pins on each of the links with your hands or pliers. To assemble the chain, you need to do the same in reverse order.

Squeeze for the chain and how to remove the chain without squeezing

What could be better than a day out of town cycling! However, pleasure can be overshadowed by unexpected circuit breakage. If domestic bicycles for the most part consist of split sections of the chain, the locks between which can be divided without much difficulty, then in sports bikes the chains are often one-piece. About how the chain is removed, and what devices there are for this, we will talk today.

Instructions for self-replacement of the squeeze chain

Usually, an auxiliary tool is used to remove the chain from the bike. a squeeze. With its help, it is easy to remove even a one-piece chain. The sequence of work is as follows:

  • Decide on the section of the chain for parsing. In the case of re-parsing the chain, it is preferable to take the non-repairable section of the chain.
  • Insert the chain into the squeeze so that the pin is opposite the clamping axis.
  • Secure the chain with the knurled screw.
  • Twist the handle. squeezing the pin out.
  • Remove unnecessary links using a squeeze, pressing out the entire pin.
  • Connect the chain links. In this case, the pin located in the cheek should point outward towards you. First, 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.
  • Unclench the “cheeks” with pliers. After the ends of the chain are in place, the outward-facing pin will prevent the links from separating.
  • Insert a squeeze into the link so that the axes of the pin and the stem match perfectly, and rotate the funnels, pressing the pin into the hole.
  • Check the symmetry of the position of the pin and the “cheeks” of the links. Correct their position if necessary.
  • Check the links for mobility relative to each other. Increase mobility with pliers if necessary.

Model without lock

In this case, it will not be easy 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 bike with improvised means in this order.

  • Screw an ordinary vice to the table.
  • Fix the chain in a vice by placing a nut on one side, the hole of which corresponds to the pin.
  • Stick on the other side with a small screw with a cap.
  • Clamping the vice, push the pin ball into the nut hole.

Summing up, we can confidently say that squeezing is an irreplaceable thing on the road for every cyclist. And if a broken chain with a lock can still be removed from a 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 above.


Before removing a connecting rod on a bicycle without a puller, it is worth making a reservation: using a wrench is the most effective method. However, the tool may not be at hand, so the master will have to show skills. During the ride, debris can get into the mount, which, due to the loads on the part, is pressed and adhered. Ways to remove connecting rods from a bike without a puller:

  • Unscrew the bolt / nut that fixes the element, drive a short distance. This will make it easier to disassemble the part for replacement or adjustment. However, there are not many chances that the element will fall off on its own. It is recommended to pour boiling water over it, then all excess accumulations will be soaked, which will make it easier to remove the product. Hot water is also useful when disassembling pedals. the main thing is not to forget which direction to turn (on the left pedal. left thread, on the right. right). Another way to improve the odds is to lubricate the mount with grease (WD-40) on all sides, then ride. It is important to ride as fast as possible to load the bike cranks.
  • Take an angle grinder and make a notch on the bushing of the part. Then, with the help of a surf, a hammer, finish off the product. After this action, the element remains only to be thrown away. you will have to pick up and install a new part on the bike.

It is most effective not to come up with methods, but still purchase a puller and change the element with its help. Repair will be easier and faster.

Cycling enthusiasts should also learn about dismantling models with a wedge. This is the most primitive mount possible. Many people have known it since childhood. it was found on Soviet and Russian bikes of the Desna model. Today the wedge is only used on bicycles from the cheap price segment. It is easy to dismantle such parts. just unscrew the nut, knock out the element (during the impact, it is better to substitute a plate so as not to damage it, otherwise you will need to replace it with a new one).

When the connecting rod is installed in place, it is important to correctly orient it and firmly fix it. If there is a backlash, the wedge and the axle will be damaged while driving. However, excessive force is not needed, otherwise it will also lead to breakage.

How to remove cranks from a bike without a puller? Helpful hints

Bicycle transmission tends to wear out even with proper and timely care. Most people, of course, do not have special bicycle tools, and if you suddenly felt an urgent need to replace its components, then, most likely, you wondered how to remove the connecting rods from a bicycle without a puller and is it possible to do it yourself? To deal with this, it is worth learning more about the connecting rods themselves and the types of carriages.

A little about standards

On bicycles of different classes, it is logical to install bicycle cranks and carriages of different standards. At the moment, the following types of carriage assembly are popular:

  • Standard square mount. the old look for budget bikes.
  • Octalink, invented by Shimano. It has several subspecies, including standards from other manufacturers that are very similar in design. In fact, it is a kind of “square” carriages, but has a redesigned shaft and modified splines.
  • Hallowtech II is considered the best option in terms of stiffness / weight ratio, but it costs more than others. Also invented by Shimano.

On older bicycles, wedges were a common type of fastening. There were quite a few problems with such a system, which is why it remained in the last century. Now they are practically not produced, and even the most budgetary bicycles are equipped with carriages with a square shaft.

Take the survey

  • One-piece. It is a one-piece piece consisting of an axle, left, right connecting rod. The design is characterized by increased strength, ease of maintenance, but it is more massive.
  • Two-piece. The left connecting rod is connected to the rest of the elements with a nut. The sprocket and the right side, the axis are one piece.
  • Three-part. Found on most bicycles. Consist of an axle, connecting rods (right and left), combined with a sprocket.

This product accounts for a significant part of the load, therefore bicycle cranks are made of hard metal (steel) alloys. There are also aluminum models, more often in sports options, expensive foreign copies. On budget bikes, a front sprocket block is installed, combined with a connecting rod, of a non-separable shape. New parts are purchased depending on the type of carriage already used. Also, when choosing, the length of the elements is taken into account.

For parts, different types of fasteners are provided, for example, a slot or a square. The second is used in expensive sports bikes. There is also an innovation. a rotary connecting rod system.

One-piece Two-piece Three-piece

How to disassemble a connecting rod without a puller?

The simplest method is to use a special puller. If there is no such tool, then in order to disassemble, remove and repair it, you need to make some effort and skill. During the ride, dirt and dust gets into the attachment area of ​​this element, the element literally sticks to its attachment due to heavy loads. In this case, you need to know how to remove the cranks from the bike without using a puller. You can fix the problem and make repairs on your own, and this will help you get to the place of equipment repair.

In unsuitable conditions, you can try the following methods in order to remove the part. If you unscrew the nut or bolt that secures the connecting rod and drive a certain distance, then the element can be disassembled and removed much easier, and in the future, replace or adjust what is required. The method is to pour boiling water over it. Consequently, all dirt and dust will get wet and making repairs to the bike, it will be easier to remove the element. This option is also suitable when it is important to remove the pedals. It is important to know and not to be confused in which direction which pedal is unscrewed. The left pedal has a left-hand thread, and the right one, respectively.

If the bottom bracket of the bike requires adjustment, the cranks must also be removed from the bike. Other recommendations will also help in case of unforeseen breakdowns. If the cable of the gearshift or brake is damaged, you need to replace it with a new one, and if there is none, then tie the torn ends. Bicycle spoke failure is also a common problem. Then a wire with a diameter of about 2 mm will help. The end of the spoke next to the rim is crocheted, and then a piece of wire is inserted, which must be passed through the socket of the hub. This replacement is far from perfect, but it will allow you to reach the goal and the place where you can repair the equipment well. Regular viewing and maintenance of two-wheeled vehicles will avoid many of these problems and make the trip enjoyable.

In what order to remove the connecting rods from the bike without a key and with a puller

Cranks are the busiest parts of a bike. Due to their simple design, they do not require adjustment and are easy to use. They have to be dismantled in the event of a breakdown or if the necessary tool is not at hand, but you need to replace, for example, the camera. You need to understand how to remove the cranks from the bike so as not to break the parts. It is recommended to work with a puller (you can do without it), strictly following the manufacturer’s instructions.

The device and purpose of the part

A bicycle connecting rod is a metal lever that has a large and a small head on the rod. This element is of several types:

How to Break Bike Chain Without Special Tool

  • One-component. They represent a single structure. left, right connecting rod, axle. The advantages of this type are great strength, easy maintenance, but they have a significant weight;
  • Two-component. Here the drive sprocket, the right connecting rod and the axle are connected, and the left one is connected separately with a nut;
  • Three-part. This most famous and popular system is the axle, the left connecting rod and the right one together with the sprocket.

The load on the connecting rod is very high, and therefore they are most often made from solid steel, but there are also options from aluminum alloys, for example, in sports type bicycles or imported models. Inexpensive two-wheeled vehicles have a front sprocket block, combined with a connecting rod and non-separable. In this case, when replacing the sprockets, both connecting rods must be replaced. New ones are selected depending on the type of existing carriage.

This part of the bicycle can also have various types of fastening, for example, square, slot. The first is used in professional sports models of equipment, and there is also the latest development. a rotary system.

Removal technology description

There are several options for removing the connecting rods. Most often, users work with a puller. it’s easier and faster. If it was not available, you should read the instructions for dismantling without this tool.


  • Install the squeeze so that its core is exactly in the center of the pin (roller).
  • Smoothly rotate the squeeze handle until the roller comes out to the level of the second inner plate.
  • Disconnect the link without removing the pin to the end.


Internet experts and connoisseurs of Soviet tales usually recommend a nail and a stone, but progress does not stand still and it is better to purchase a chain squeeze (chaintool). a simple tool that resembles a child’s vice without a bed, which can be purchased for 500-1000 r.

It makes sense to keep the squeeze in a backpack only during difficult multi-day hikes, usually this is a workshop tool, so when choosing, you should not pay attention to light versions and squeezes in multitools. they are usually unreliable and are thrown away after 5-10 uses.

If there is no squeeze nearby, a hammer, a couple of nuts and a nail will help, but more on that later.

Cycle chain design and its features

A bicycle chain is a fairly simple metal structure, the main purpose of which is to transfer torque to the rear wheel. Large dynamic loads during riding lead to wear on the chain mechanism, therefore the cyclist needs an idea of ​​the device.

The chain consists of separate links, each has:

  • inner and outer plates;
  • pin (axis);
  • roller;
  • sleeve.

The main difference in designs is the presence or absence of a lock. The locking bicycle chain has a special clamping device, a lock. Such a device is more convenient for repair, but in operation, a solid structure is more reliable, it has fewer weak points.

On singlespeeds, the chain runs straight along the sprockets, practically without deviations, and may not change during the entire life of the bike. With high-speed bikes, everything is more complicated: there is no straight line between the front and rear sprockets, the chain is at an angle relative to the frame. Therefore, owners of high-speed bicycles have to think about how to remove the chain more often. Timely replacement of the chain mechanism will avoid wear of the entire transmission structure.


Their design is extremely simple. there is a cheek on which 2 pins are located. They are pushed into the holes in the chain links and pressed in with a double-hole washer. Everything is fixed with a locking cheek.

Features of work in the absence of squeeze

Lack of squeeze is not a problem either. Instead of squeezing, a pin is enough. a nail, a drill, a dowel, slightly smaller than a roller in diameter, and a hammer with which this pin will knock out the pin

The main thing is the accuracy of the actions, it is important that the blows do not bend the link plates. for this, a nut or other amplifier is laid under the chain and inside the link.

If shortening without squeezing will be done for the first time, it is recommended to practice on an unused link, since the work will require skill. In addition, without squeezing the chain, in any case, you will have to remove the chain from the bike, since you need a solid support.

View 1: Chain lock with two pins

I have not seen such locks for a long time, but they are still used for single-speed chains and on old Soviet bicycles. For example, KMC MissingLink 1 sp Z410-SO lock.


The main sign that something went wrong is considered to be inaccurate gear shifting; extraneous noise when driving.

The express diagnostic method helps to determine without special tools that the chain needs to be replaced. Set the speed selector to the largest sprocket. Pull the chain away from the teeth. Estimate the resulting gap. If it contains more than 4 teeth, then the bike chain needs urgent replacement. Two prongs “warn” that of course you can ride, but wear is just around the corner.

In general, it is necessary to decide how to remove the chain from a bicycle in the following situations:

  • the need to replace an old part;
  • installation of new speed switches on the bike;
  • shortening the length by several links;
  • cleaning the structure from dirt and adhering debris.

How you can extend the life of your bike chain

Despite the fact that removing and replacing a bicycle chain is not a laborious procedure, it is still better to keep this element so that it can last as long as possible. Many people mistakenly think that the “life” of a chain depends only on its cost and quality characteristics. A more expensive bike drivetrain will allow you to slightly reduce weight, and the clarity of the shifting will become more.

Naturally, these are very important aspects. Either way, it’s best to choose bike tools and accessories from trusted manufacturers. However, even an expensive chain cannot last long if it is not spared at all while riding. So, let’s take a look at some of the secrets that will make you need to replace your bike chain much less often:

remove, bicycle, chain, puller
  • Do not overload the chain while cycling. For this, it is enough to switch in a timely manner. It is for this purpose that bicycles are equipped with derailleurs and shifters.
  • If at the moment heavy loads are imposed on cycling, it is better not to switch.

Is it possible to remove the chain without using a squeeze

Many people are worried about whether it is possible to remove the chain from a bicycle without such a device as a squeeze. There is an important rule to remember. If you want to achieve excellent results, you should use specialized tools designed for certain types of work. To remove the chain, you still need to use a squeeze. In the process of performing work, only high-quality and reliable bicycle tools should be used.

Nuances of the procedure

In addition to the basic algorithm of actions, some more points should be taken into account. If the chain has been removed several times, you will need to close a new link each time. This is necessary because these elements can become loose. There are certain models of pomace that are equipped with two seats. The performer will need to fasten the links extremely carefully.

Features of removing the chain on a bike

How to remove a bicycle chain that has a lock

It is much easier to remove the chain with the lock. Therefore, before starting work, you should carefully inspect the chain itself. If you find a link on it that is radically different from the others, we can say that you are in luck. To disconnect it, you will need to move the pins on the links. The circuit will then open. This process takes no more than a couple of minutes. You do not need to use any special equipment. If you are unable to move the pins with your hands, you can use pliers. Fastening is carried out in the reverse order, so there will be no problems.

How to remove a chain in the absence of a lock

If there is no lock, the performer will need to make some effort during the operation. You should use a special squeeze, which will allow you to squeeze out the pin without difficulty.

You will need to place the chain links in such a way that the release axle is located opposite the pin itself. Attention should be paid to ensure that the pin does not jump out in any case, since returning it back is a rather complicated procedure. After you have removed the chain, you can start replacing or repairing it.

When you need a bike chain replacement

You will need to master the skills of removing the bicycle chain in such cases:

  • To replace a worn chain that is unsuitable for further use with a new one.
  • In order to install new speed switches on the bike.
  • When shortening the bike chain.
  • When cleaning this item.

If such situations arise, one way or another, it is absolutely impossible to do without removing the chain. Therefore, you should familiarize yourself in more detail with the features that this process involves. In fact, removing the element itself will not take a lot of your precious time. It will be enough just to just know some of the nuances that you have to face in the process of doing the work.

Element removal process

Now let’s proceed directly to removing the bike chain. So, today there are a certain number of types of this device, but the process itself facilitates the fact that they all have a similar opening principle. The bottom line is that you need to close the axis, after which you can remove the cover. To make the task more convenient, it is good to use pliers or special opening pliers. Thanks to these accessories, removing the chain will not take much of your time. You can quickly fix the breakdown, or change the chain on your bike.

Work process

Removing an element with a lock does not take much time and effort. Today there are several varieties of this bicycle chain device, but the principle of their opening is similar. It is necessary to close the axles and remove the cover. For convenience, you can use pliers, it is also good if you have pliers for opening at hand. Thus, the whole procedure does not take much time and it will be possible to quickly remove the malfunction, change the part or remove the chain from the bike.

Bicycle Chain Replacement. No Specialty Tools Required!

If there is no lock, then you need to make some effort. For work, you need a special squeeze. It is a tool with which it is very convenient and easy to squeeze out a pin. To work, place the chain link so that the release axle is directly opposite the pin. Then you need to twist the handle and squeeze out the pin itself. It is very important not to allow it to pop out, otherwise it will be very difficult to insert the pin into place correctly. Further, the bicycle chain can be replaced or repaired.

There are also some points to consider when working. For example, there was repeated removal of the same bicycle chain, then the next time it is necessary to open another link and segment, because after this process it loosens a little. Also, some models of pomace may have two seats and you need to fasten the link carefully, correctly and carefully.

Maintenance: DIY bike chain repair

Two-wheeled vehicle repair skills will help riders deal with difficult issues quickly and efficiently. The most common question of concern is how to remove the chain from the bicycle. At any time, unforeseen situations or the need for maintenance of equipment may arise and therefore several recommendations will help.

When is it necessary?

This procedure may be needed at the following points:

  • Replacing the old part with a new one;
  • Installation of new speed switches on the transport;
  • To make the chain shorter;
  • To clean the element.

Design and its features

A bicycle chain is a fairly simple metal structure that is designed to transfer the drivetrain from the drive sprocket to the driven one. Component elements:

The main difference between the different types is the distance between the rollers and the width. In some modes of transport, this part may be part of the gearshift system. This detail is important and requires special attention.

A bicycle chain requires regular maintenance, cleaning and repair to function properly. Periodic lubrication and flushing will ensure that the equipment works well, and every few thousand kilometers the chain must be replaced with a new one. There is also a certain indicator of the degree of elongation (0.5%), that is, the pores when a new part is needed. Without special tools for measuring, you can determine the degree of wear as follows: you need to install the element on the largest sprocket (leading) and pull it off, moving it away from the teeth. If the resulting space contains more than 4 teeth, then the bicycle part must be urgently replaced.

How to remove a bicycle chain?

The bicycle chain is one of the key transmission units of any bike, which directly transfers the rotational-translational energy of the rider’s legs to the rear wheel, which sets the entire unit in motion. In this case, the chain is subjected to the most intensive work and various external influences of a destructive nature, which means that it needs careful care, prevention and ensuring the initial working condition.

Depending on the conditions of use of the bike, if it happens occasionally in favorable sunny weather, you can limit yourself to simply cleaning and lubricating the chain without removing it. But when riding happens regularly with extreme elements, including rough terrain, landscapes, rainy, windy weather, etc., regular wear and tear occurs and the need to remove the chain from the node for thorough washing from dirt in special solutions, lubrication, possibly a complete replacement or in separate cases. adjusting its length.

You need to know that bicycle chains are produced only taking into account the compatibility of various transmissions and are available with or without a coupling lock and, accordingly, are called locking or clamping. A separate global manufacturer is trying to develop its own sound technologies, proprietary developments in connecting mechanisms and implements in each model, adhering to certain principles.

Chains with a lock are considered more practical, especially in assembly and disassembly, which do not require much effort. Clamping devices represent a monolithic structure, which means it is more reliable, but they assume the presence of a special tool. squeeze, the handling of which requires experience and work skills, which is hardly suitable for beginners.

How to remove a chain without a lock?

First of all, you need to choose a link that will be sorted out. If this happens for the first time, it does not matter what it will be, if possible, look for the link with which the chain was connected at the manufacturer’s factory (as a rule, it stands out). However, if this has already happened before, it is very important to choose a new one, and not the link that was dismantled, otherwise the probability of rupture increases.

Next, we arm ourselves with squeeze. This is a special tool like a miniature press with the same extrusion wedge. We install the selected link in the squeeze, carefully fix and squeeze out the axle using the rotating handle of the press. It is strictly not recommended to extrude the axle to the end if you do not plan to replace it, otherwise it will be very problematic to insert it into its original place. It should remain in the opening on the back of the link cheek, so that there is room in the middle. The chain is removed. For the installation process, everything happens the same, only in reverse order.

remove, bicycle, chain, puller

How to remove the lock from a bicycle chain?

Carefully inspect all the links of the chain, usually the lock has a prominent shape with larger holes for pins, or in the form of an elongated horseshoe, an elongated oval and similar nuances. You will need to loosen the chain in the area of ​​the lock, this method is also great for installation. For convenience, you can use a wire or make a bracket out of it and fix it on the links on both sides of the lock so that it sags down, somewhere two or three links from the connection, and more, as it is convenient for you. To keep the chains in a slack state, special holders are sold, you can use them. Further, if you cannot remove / fasten the lock manually, then use ordinary pliers and slide the pins (axles, pins) on each half of the lock cheeks. the circuit will open. There are special pliers on sale in the form of a movable trident for opening and closing locks, which can be purchased, it will be easy to work with them.

Removing the chain from a bike

It happens that you need to remove the 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 chain length accordingly by adding or removing a certain number of links).

Examine the chain: if you find a link that is different from all the others, then you are in luck. you have a chain with a lock. In order to disconnect it, slide the pins (pins, axles) on each half-link (cheek). The circuit will open. The whole operation will take just a minute. You do not need any special equipment: if you suddenly cannot move the pins with your hands, use the pliers. The assembly is also done without any tricks, in the 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 squeeze for the chain. It is inexpensive, it 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 squeeze and reconnect the chain.

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

How to remove a chain without squeezing is a topical 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, this is the squeezing of the chain.

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

Suppose the chain is laid correctly. Now gently rotate the handle. The effort may have to be significant, so try to work carefully so that the link in the squeeze does not skew, otherwise it can be damaged. Make sure that the tip of the squeeze is pressing exactly on the pin. You do not 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 squeeze it out completely, then, believe me, it will be very difficult for you to insert it back. Also, be careful not to inadvertently knock the pin out of the cheek, as it can roll away in an unknown direction and get lost.

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

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

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 a pin without a tool, right in the field. by placing the chain on the edge of a solid 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 device. a squeeze, it is best to take a multitool, which includes all the main bicycle keys, including a 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 it’s simple. 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.

“The main thing is to stop at the end so that the pin does not pop out completely, otherwise your vocabulary will not have enough swear words to push it back.” I fully confirm =) I put a pin for 1 hour

Viktor, a question: there used to be a chain with locks (lock), now I bought a new chain that comes with an installation pin (spike). When installing locks, do you need to remove one link from the chain, since the chain will lengthen by the length of the lock, or installing the lock will not lead to excessive lengthening = chain sagging and you can ride without bothering about this topic?

Vladimir, if it’s still relevant: the new chain needs to be adjusted to size anyway. The simplest and most common (and, in my opinion, correct) recommendation is to put the chain on large stars in front and behind (past the switch, just on the stars) and leave 2 links if the chain is with a pin and 1 link if you want to put a lock. The rest must be removed. The main thing, before closing the circuit, do not forget to stretch it along the rear derailleur, so as not to get a semi-fix

Good afternoon friends! The question arose. does the grip of the pin with the plates weaken after removing and reinstalling it and can it lead to its rupture??

The main thing is to try not to squeeze out the same pin more than 1 time. Then it can start to tear. And you cannot squeeze out the connecting pin, it is disposable. On a children’s single-speed bike, the chain somehow began to break, I had to rivet this axle. But there the chain is different in design.

Victor, thanks for the article! There is a need to tell you about locks for a bicycle chain: how to choose the right one, how to change it correctly, etc. Thank you!

Thanks for the site and article! Unfortunately, when replacing the chain, I messed up: they put the chain 2 links longer (Merida Matts 20MD chain SHIMANO HG40) stood from the factory for 108 links and put it on 110 links and a cunning UG51 lock consisting of one plate with a notch and a link with two pins 1. then the lock is easy but you can’t remove it. How to remove such a lock? 2. If there was a chain with 108 links and put it on 110 than it threatens?

Paul, two links are not a reason to worry.

What I didn’t understand is the removal of the chain if there is no lock. Does the squeeze remove the devil’s problem from any link in the chain or only with the lock? If the chain is removed without a lock, the question is why the lock ?

Vadim, the lock is needed for convenience, and with the help of a squeeze, the chain can be shortened or removed the damaged link. Thanks for the article, everything is available and clearly written)

Anton Chernyshev. 05/31/2014 at 06:16 Vladimir, if it is still relevant: in any case, the new chain needs to be adjusted to the size. The simplest and most common (and, in my opinion, correct) recommendation is to put the chain on large stars in front and behind (past the switch, just on the stars) and leave 2 links if the chain is with a pin and 1 link if you want to put a lock. The rest must be removed. The main thing, before closing the circuit, do not forget to stretch it along the rear derailleur, so as not to get a semi-fix

Can anyone explain in more detail what it means to leave 2 links? Does it mean that two links hang like “extra”? What does a chain with a pin mean??

“Therefore, to remove the bicycle chain, you need to have a special device. a squeeze, it is best to take a multitool, which includes all the main bicycle keys, including a squeeze.”

That is, there are multi-keys with squeeze? I have not met something. Squeezing is a must-have attribute in a cycling trip.?

there is a link in the same place, you can see how I use a multitool with squeeze.

“Is squeezing a mandatory attribute in a cycling trip?”

of course. Even just in pokatushka it is desirable to have it.

I am interested in such a question. when installing a lock on a chain, you need to remove one link?
