How To Put A Chain On A Speed Bike

How to choose a new bike chain?

If you don’t know what kind of chain and size fits your bike model, clean the outside of the plates from the dirt and look for the manufacturer’s name. Sedis, Sachs Taya. The most famous manufacturers of standard chains. Shimano riveted chains use the markings. UG, HG and IG. When replacing, also make sure that the widths of the new and old chains match.

How To Put A Chain On A Speed Bike

A standard 2.4mm chain is best suited for a rear hub block (the center pivot of a bicycle wheel designed to accommodate a stationary wheel axle) with 5 sprockets. More expensive chains are installed on bicycles with 6-7 sprockets. On bikes with 7-8 sprockets, it is best to use high quality flex chains. Of course, you can also supply a cheaper chain from a little-known manufacturer, but it is quite possible that it will soon need to be replaced.

How to remove and install a new chain on a bike?

The old chain is usually removed with a special tool. a squeeze. Using this device, one of the pins of the chain is squeezed out (the pin that connects the links). After the links open, you need to turn the pedals so that the chain sleeps.

It is more convenient to install a new chain when the bike is suspended or resting on a horizontal surface. Before putting on the chain, you need to set the speed switches correctly: rear. at maximum speed, front. at low speed. The end of the chain is passed between the rollers of the rear derailleur, forming an even shape S. The chain is then slid onto the smallest rear sprocket, then onto the front derailleur and onto the small front sprocket. Only after that the ends of the chain can be connected, check if it is firmly installed and rotate the pedals.

How to choose a bike chain and install it correctly?

The bicycle chain is an important part of the chain drive, which transfers the muscular force of the legs to the wheels, sets the bicycle in motion. This part allows you to convert human energy into mechanical energy from a bicycle. The chain transfers to the rear wheel 95% of the forces that are applied to the pedals.

Bicycle chains differ in the width and distance between the axles that hold the chain links together. The chain width is measured between the inner planes of the plates.

Sizes of standard chains that fit most bicycles:

  • 1/8 ” (0.125 “, 3.2 mm)
  • 3/32 in. (0.094 “, 2.4 mm)

How to properly maintain a chain?

The chain will wear out quickly enough, especially if it is not periodically cleaned or lubricated. Here wear it lengthens. You can check the condition of the chain by lifting it over the sprocket teeth. The new chain is lifted by 1-2 mm. But the chain needs to be changed when the stretch increases to 7 mm. When replacing the chain, you will have to change the rear hub sprockets at the same time.

If the chain is covered with normal road dirt, it can be easily washed off with a hose stream. But if the dirt is mixed with oil, use a clean rag. Remove any dirt between the rear hub sprockets, wipe the carriage sprocket teeth. Next, spray solvent between the chain links and clean them with a toothbrush. Cleared the chain, contiguous it with oil.

In good weather, the chain should be dry and clean, and during rain and frost, it should be Lubricated abundantly. Experts recommend changing the chain more often because it costs less than cassettes and systems. And the new chain will extend the life of the entire system. In mountain bikes, it is better to replace it every 2000 km, in hybrids and mountain bikes. after 3000-6000 km.

No tools

In the absence of squeeze, you can install everything back without it. Pliers and any strong cylinder, for example, a small hexagon, will help. Gently clamp the cylinder, the pin can be riveted similarly to the work of the squeeze, it just requires much more attention and application of forces.

Models with a lock can be disengaged by using a tight rope or cable. This allows for prompt repairs literally in the field, for example, when the chain suddenly breaks on a short hike.

The most important components of a bike are the drivetrain and the chain. And wear and chain selection is just fundamental. And you need to know how to maintain it, since in the process of work it stretches and weakens, therefore, it is better to know how to remove and put the chain on a bicycle after buying a new one.

With chain wear, the operation of the switches deteriorates noticeably, very cheap chains can even stop moving to other stars, even not completely wearing out. This happens because the chain has a special shape, and the stars are protrusions that catch the chain and pull it on the stars when shifting. Even with absolutely finely tuned, the speed switch can switch poorly precisely because of a worn chain.

How to put a chain on a bicycle

Changing the bike chain. Process

Let’s take a step by step how to remove the chain from the bike:

  • We clean the links from dirt. it will interfere with each subsequent step.
  • Removing the rear wheel is NOT required, but it’s much easier to work without it.
  • Extrude the pin (the metal cylinder that closes each link) using a squeeze.
  • Disconnect equals link.
  • Remove extreme links from switches.

The reverse sequence is the same. put the chain in place and assemble the structure back, rivet the pin with a squeeze, and rotate it in the opposite direction.

Conclusion

Removing the chain from a bike is very easy if you have a simple tool or basic knowledge of the process. The most important thing is to act carefully, as forceful action with extrusion can be dangerous.

Standard withdrawal process

All guides describe the same removal procedure. This will require, first of all, a small set of tools. without them it will be quite difficult.

How to remove the chain

A special repair tool is required to remove the chain from the bicycle transmission. Squeeze, but it is better to photograph (sketch) the position of the chain and switches, so that in the future there are no problems with the installation.

It is necessary to install the chain squeezes opposite any roller and gradually tighten the screw so that it pushes the pin out. Then the tool is gradually loosened and retracted, and the chain can be easily removed by pulling.

Tools

  • Key for removing the rear wheel;
  • Pliers for holding segments and pin;
  • Forcing. a device for pressing out pins, without a lock. the most important tool in the process.

No lock

If there is a chain on the bike without a lock, then you will have to press it out of the chain link. Also, this process will need to be carried out in order to reduce the number of chain links when necessary.

A special tool is required to press out the chain axle. Forcing the chain. For this operation, you can select any link in the chain, the only condition is, when re-pressing it is better to use a new one, since after the operation the link loosens a little.

Insert the chain link into the tool and secure with the screw. Please note that some chain releasers have two seats, one for pressing out the axle (it is closer to the fixing screw), and the second place is used only for adjusting the axle. We tighten the squeeze screw carefully, thus squeezing out here.

DO NOT squeeze out to the end if you plan to assemble a link with the same axle, otherwise it will be problematic to install it back!

How to install a chain on a bike

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

To install the chain, move the front and rear derailleurs to small sprockets. Then thread the chain through the derailleur tension frame, and do not mix up directions, the lower roller runs the chain to the left and the upper case.

We connect the open links, Install here. Insert the link into the chain squeeze and secure with the fixing screw. Rotate the chain release handle to press it into place, it should be level with the edges of the chain. We take out the chain from the squeeze, if necessary Break off the end of the axle.

Check that this chain link bends freely, if it goes tight, then you need to adjust it with a squeeze. Insert the link in this case into the second squeeze seat, then you can see both ends of the axle.

Chain adjustment on speed bikes

To save money, some craftsmen “cut” the chain, that is, cut it and reduce the number of links. This option is, of course, also possible, but it is important to understand that a stretched chain is a worn-out mechanism and it will not last long.

For people who still remember the Salute bicycles, the suggestion “choose a new chain for a bicycle” sounds somewhat wild. The answer is simple: in those bicycles only one speed was provided, so the chain was constantly in a calm state and did NOT wear out as quickly as on modern bicycles.

For bicycles, chains are produced with and without locks. In this article I will write how to remove the chain from the bike for cleaning and lubrication or to replace it when it is already worn out.

Fitting a bicycle chain.

On domestic road bicycles, the chains are made split, one segment of such a chain has a special lock. On sports bicycles, it is not possible to make a detachable chain, because this lock interferes with gear shifting.

When buying a new chain, you need to find out which chains fit the system and cassette installed on your bike.
For 9-speed cassettes, use a 6.5mm chain, for example, SHIMANO CN-7701 or CN-HG93.
For 6.8 speed cassettes, use a 7.1mm chain, for example, SHIMANO CN-HG50 or CN-IG51.

Chains are sold in two types. Boxed and standard (almost like computer components in Retail and OEM supplies). Usually, the box contains a replaceable here, designed to connect the chain segments. One end of such an axis of points, which makes it easier to install. After it is pressed in, this pointed end must be broken off by the pliers.

If the chain is not equipped with a special axle with a pointed end (like many chains sold without a box), then it should be inserted into one of the segment plates.

How to quickly pull a chain on a bike

The most popular manufacturers are KMC, Shimano and SRAM. In the line of THESE manufacturers you can find chains of various and different qualities. All these chains easily replace each other and, if the cyclist has a desire, he can go over the chains indefinitely, until he finds the one that will completely suit him. When purchasing a chain, you should pay attention to the marking: usually firms put information as a chain in the Model Number.

Also, extraneous sounds from a lubricated chain often signal that it is worn out. TIP! Experts recommend to have three chains “in the farm”: each of them should be operated for 500-600 km, then change them, choosing the shortest.

How to install a chain on a bike

Let’s start disassembling the bike chain. Everyone knows why you need a chain on a bicycle. Next, you need to put a chain on both sprockets of the bike. On regular road bikes, the chain is not that difficult to tighten. For some reason, then the chains served hardly longer than the bicycle itself. The fact is that in such bicycles the machine is responsible for the chain tension. In order to Disconnect the bicycle chain, we installed a special lock on it, shown in Fig. 14.

An essential element for the bike’s performance is the chain, the life of which depends on timely care. When working, it should not crack and creak. When adjusted correctly, the chain should have a slack of 10-12 mm. When pulling with your fingers, it should give in by 10-15 mm, and if this value is greater, then it must be pulled. Note that this is only relevant for bicycles with or without derailleurs, or with planetary gears.

When the chain is too tight, it becomes very difficult to pedal on the bike, the parts of the chain drive wear out quickly. The amount of chain tension on a bike with a rear parallelogram derailleur is set entirely by the force of the derailleur spring. But if the chain is too long, then this tensioner will NOT be able to compensate for its sagging, and it will begin to hit the frame. This is especially true for bicycles with a short rear thrower.

This primarily applies to full-suspension bicycles. Very often, when installing a new chain on a high-speed bike, it is necessary to shorten its length, that is, remove several links. It will be more correct to adjust the chain length on double suspension, pressed the rear swingarm to the position when the front sprocket cassette is as far as possible from the rear ratchet.

The chain starts to slip when the tension is released due to the extreme tension. If this is not the first time you pull up the old chain, get ready to replace it soon. The bicycle chain is one of the most important parts of this mode of transport.

In addition, they are the driven link of the bicycle gearbox. At the same time, it is not difficult to guess that if the chain jumps off, the transport will NOT be able to go further. In the event of a collapse or breakage of the bicycle chain, with the best outcome, the driver will get off with the fact that he will NOT be able to continue to ride. But often there are more serious consequences. For example, if there is no special guard on the rear wheel, the chain can fall into the spokes, but here the outcome is unfavorable in all cases.

The next risk of chain breakage or loosening applies to bicycles that do not have a handbrake. Before you start to tension the chain, it is important to understand one truth.

Another symptom that should alert the driver is if the chain began to slip. To begin with, the problem of sagging is most often encountered by owners of regular single-speed bicycles. The thing is that here the chain is NOT able to tension automatically, as in mountain or other similar types of bicycles. There are two reasons for this. Firstly, any chain has the ability to stretch, do not look at the fact that it is made of metal.

With lock

To remove the chain, you need to open the lock. There are several types of locks, but the processes for opening them are similar, for this you need to close the axles of the lock and remove the cover.

If you have problems opening the locks, you can use tools such as special pliers to open locks.

No tools

In the absence of squeeze, you can install everything back without it. Pliers and any strong cylinder, for example, a small hexagon, will help. Gently clamp the cylinder, the pin can be riveted similarly to the work of the squeeze, it just requires much more attention and application of forces.

Models with a lock can be disengaged by using a tight rope or cable. This allows for prompt repairs literally in the field, for example, when the chain suddenly breaks on a short hike.

Chain Removal Situations

Maintaining your bike is very important, and there may be several reasons for removing the chain:

  • Deep cleaning. it is recommended to remove all elements from time to time and clean from grease and accumulated abrasive.
  • Link damage and replacement.
  • Replacing a worn chain.
  • Change in length with a new combination While, for example, on a mountain bike.

Home wear is primarily determined by stretching. An overstretched chain is cause for concern, as link misalignment will severely damage the sprockets and can be hazardous to derailleurs.

It is quite difficult to notice wear by eye, and to determine it there is an indicator. the length of 24 links:

  • If it is 305 mm (304.8 value for a new set), everything is in order;
  • 306.5-307.5 mm. it’s time to change;
  • 307.5 mm. if the bike was still in use with such wear, then most likely the entire set of sprockets is damaged;
  • 308 mm. the value of the damaged transmission.

Objectively, it is recommended to service the transmission every 500 kilometers, but this value is NOT Fixed, since 50 kilometers on rough terrain with an abundance of sand and mud in wear can correspond to another thousand on clean city roads.

Some people prefer to cut the chain, but the stretching is usually evenly distributed, and the links can still damage the stars, which can no longer be repaired.

»How to put it on correctly. Important points

In addition to conventional devices, there are models with a lock. a special link, which is slightly different in shape from the others, and allows you to open the link with the help of reverse tension without using a squeeze or other tools, the main thing is to correctly put the Castle link. It is not recommended to open the links next to the lock, as this will reduce the reliability of the entire mechanism.

It is very important to remember how the chain is connected to the system, cassette and switches before starting the removal. without a little experience in installation and dismantling, it may be difficult to put it back on.

Let’s take a step by step how to remove the chain from the bike:

  • We clean the links from dirt. it will interfere with each subsequent step.
  • Removing the rear wheel is NOT required, but it’s much easier to work without it.
  • Extrude the pin (the metal cylinder that closes each link) using a squeeze.

DO NOT squeeze out to the end if you plan to assemble a link with the same axle, otherwise it will be problematic to install it back!

How to remove a chain with a lock

As already mentioned, this process is very simple and in most cases, no special tools are required. Despite the wide variety of types of locks, they all disconnect in almost the same way. If you still cannot open the lock manually, you can use a special tool (see Fig. Below).

Variety of bike chain locks

Disconnecting the chain lock

How to remove a chain from a bike without a lock

If the chain does not have a lock, then a tool is needed to remove it. squeezing the chain. Without squeezing It is quite difficult to disconnect the chain and the chance of damage to the chain links is very high, and it is almost impossible to connect a chain opened in this way. If the chain has to be removed often enough, then it is better to have such a tool in your arsenal, squeezing the chain greatly simplifies working with the chain without a lock.

In order to Disconnect the chain without a lock, it is necessary to press out one of the pins (here is the link), just for this procedure we need a squeeze. Any link is suitable for this operation, but it should be borne in mind that the next time you press out it is worth choosing a different link, since with each pin it looses more and more. Ideally, a connection lock should be purchased and installed.

So, we proceed to the direct riveting of the chain. The chain link must be inserted into the squeeze (as in the picture below). It should be borne in mind that most pads have two grooves for placing the chain, in this case you need to install the chain in the groove closer to the fixing screw. The second groove is only needed for adjustment.

One end of the pin must remain in the link

Removing and putting on the chain on the bike

Quite often it becomes necessary to remove and then put the chain back on the bike, for example, when cleaning the chain, replacing or changing its length. For such an operation, the bicycle chain must first be properly disconnected and then reconnected. This process is very easy if the chain has a special connecting lock, but if the chain is without a lock, then a special tool is required to disconnect it. a chain squeeze. What other tools may be required for repair, we read in our article. tools for repairing a bicycle. Let’s take a closer look at the case with and without a lock.

Bicycle chain extractor

How to put on a chain on a bicycle without a lock

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

Correct chain position

Further transitions to the direct connection of the chain link. To do this, it is necessary to carry out the same operation, only in the reverse order. By placing the chain in the groove near the fixing bolt so that the protruding pin faces the squeeze nose. By twisting the handle, smoothly push the pin back until it is completely inserted into the link. After this procedure, the links in which the pin was pressed should move freely, if this does not happen, then you need to use the adjusting groove of 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.

Chain links Must move freely!

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