How to chain a speed bike

No lock

If the bike has a chain without a lock, then you will have to press the axle 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.

To press out the chain axle, you need a special tool. squeezing 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 in some chain releasers there are two seats, one for pressing the axle out (it is closer to the fixing screw), and the second one is used only for adjusting the axle. Tighten the squeeze screw carefully, thereby extruding the axle.

Do not push the axle 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 chain a bike

How can this be done? To begin with, it is reasonable to simply understand whether it is necessary to engage in tensioning the chain on a bicycle or change it, since this step is important for adequate work great. There are several signs to determine the need for this work.

If, when moving, it began to rattle and jump off a little and now and then slips, then this is the first sign that it requires a new tension or it needs to be shortened.

If you visually noticed that the bike part began to sag more than usual (since the chain does not stretch all the way, then it should have a slight slack, but if the length has increased noticeably, it means that it has stretched and needs to be pulled or changed).

If on a speed bike it has become difficult to adjust the gearshift settings. And when you clearly understand that it’s time to clean the chain.

On regular road bikes, the chain is not that difficult to tighten. To do this, you need to remove the rear wheel and pull it back in the fork. Weak tension and strong tension are equally problematic when driving, so it is important to stop in time so that the chain has medium tension.

If it is stretched to such an extent that it is no longer possible to cope with a simple suspension of the wheel, but you do not consider it necessary to change it, since it slips noticeably, then it makes sense to remove it and knock out one or more links and shorten it in this way. This is not a difficult action. In this case, your task is to ensure that the length of the chain is the same as it was originally. If you are not sure that you can re-fasten the chain, then it is better not to take this step.

How to tighten the chain on a bike at speeds such as a mountain bike? For a high-speed bike, if tightening the links in the first two methods did not give the desired result, then you can try two other methods.

The first method only works for high-speed bicycles that have already traveled with a weakened spring, that is, with an old derailleur. On a new one, you simply cannot do it manually. The first step is to remove the links from the gears. Next, knock off the stopper on the switch and rotate the switch in the direction of greater spring tension.

The second method of chain tensioning on a bike at speeds is not difficult at all, but sometimes it works.

How to Tension Your Mountain Bike Chain?

Every cyclist should not only be able to ride his two-wheeled friend, but also be able to properly care for him, including pulling the chain on the bike.

Many questions arise with mountain vehicles.

We recommend that you put all your business aside and familiarize yourself with the information provided on how to correctly and quickly tighten the chain on a mountain bike. This knowledge will be useful to you more than once.

The chain is one of the most important parts of a bicycle and requires proper installation and adjustment.

The bicycle cannot be called a very complex device, there are also more complex ones. But still, there are several important and irreplaceable elements in its design, on which the operation of the entire mechanism directly depends. The chain always takes an important place. It will work for a long time only in the case of correct, timely and complete care.

It is necessary to monitor its work and promptly respond to emerging problems. For example, a correctly installed and serviceable chain should not emit extraneous sounds in the form of crackling and squeaking. During the operation of the bicycle, this element can stretch and be subject to wear.

If the installation and adjustment of the chain was done correctly, then it should sag by 10-12 mm, no more and no less. Pulling the chain with your fingers, it should move 1-1.5 cm from its original position.

With more pulling, it is necessary to urgently tighten the chain.

These regulations apply only to two types of cycling: models with no speed switch or with an installed planetary gearshift mechanism.

When a new chain is installed, it is imperative to adjust the tension level, and after three trips, it is necessary to tighten it. The new mechanism is prone to fast stretching.

Bicycles are now different, with significant differences in design. To properly tension the chain on a bike, you need to know the rules that apply to your type of vehicle.

How to make a bike chain tensioner

To save even a little, you can make a bike chain tensioner yourself. But first of all, you need to understand why you need a chain damper (aka tensioner) on a bicycle. This accessory is a protective element for bicycles.

Thanks to the damper, the tension level of the chain mechanism is regulated in order to exclude the reduction of oscillation when overcoming obstacles (jumping on stones, rails, etc.). In addition, the tensioner provides protection against mechanical damage and the chain slipping off the sprockets.

A damper is used on bicycles with a single speed or internal shifting mechanism.

How & When To Change A Chain On Your Road Bike

Removing links

Collapsible chains are placed on a regular bicycle without speeds; they have a lock on one of the links.

On most modern bikes with speeds, non-separable chains are used with all the links equally well riveted.

It is not difficult to disassemble a one-piece riveted chain, it is enough just to grind the heads of the pins on one of its links on emery. It is even easier and more accurate to disconnect the rivets using a special tool. squeeze.

It should be noted that pomace is a versatile tool. With its help, you can not only squeeze out the locking pin, but also re-rivet the disassembled chain.

Many squeezes have two working grooves: one is needed for pressing the pin out of the roller, and the other is for pressing it in. A mounting location farther from the pressure screw is for ripping the chain pins.

You can learn more about using such a tool in the following video.


First you need to figure out whether the mechanism needs to be tightened? On ordinary bikes, it is not difficult to understand everything. The method for adjusting the chain on a bicycle is simple enough.

  • Turn your two-wheeled vehicle upside down, pull the mechanism down with your fingers until it stops. (If the chain stretches and sags by no more than 10-15 mm, then there is no need to pull up).
  • If the tension of the bicycle chain does not lower it below 5 mm, it is necessary to immediately loosen.
  • Chain adjustment on speed bikes

    To save money, some craftsmen “cut” the chain, that is, cut it and reduce the number of links. Of course, this option is 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 Salyut bicycles, the suggestion “to 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.

    How To Fix Bike Chain Skipping/Slipping/Jumping Gears

    How to chain a bike at speeds

    An important 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. It is normal that during operation it gradually wears out and, as a result, lengthens.

    When adjusted correctly, the chain should have a slack of 10-12 mm. When pulled 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 or without derailleurs, or with planetary gears.

    It is also important to adjust the tension when installing a new chain. It is even more important to tighten it after the first three arrivals. A new part stretches very quickly during the first time of operation.

    Regulation on a multi-speed bike

    The chain tension on a bike with a retractable parallelogram derailleur is completely controlled by the force of the derailleur spring. However, if the chain is too long, then this tensioner will not be able to compensate for its slack, and it will pound on the rim. This is especially important for bicycles with a short return thrower.

    Too short a chain makes it difficult to shift gears. It will be a factor in the increased wear of transmission elements. The main priority is to have to do with two-suspension bikes.

    To determine the length of the chain, try swapping it over the large front and rear sprocket. and if the chain is tightly stretched, then it is short. If it sags too much, it will be long.

    Often, when mounting a new chain on a high-speed bike, its length should be shortened, that is, a number of links should be removed.

    There are 2 methods for finding how many links need to be removed:

    • Place the chain on the largest stars in front and behind. Pull on it, moving the last toggle switch up to the border in front. Now it only remains to add 2 links, and the best length will be established.
    • Throw the chain in front of the maximum sprocket, and behind the smallest sprocket.Pull the chain until it is located, in which case, the frame of the backward sprocket will direct exactly downward, more specifically, if the axes of the derailleur rollers are in one plumb line.

    On double suspensions, it will be better to set the chain length by pressing the last swingarm down to the position if the front sprocket reel is pulled out of the rear ratchet as much as possible. By marking the required length, unnecessary links can be removed.

    Fitting the chain to the bike

    Before setting up the chain, you need to make sure whether it will fit for a large one according to the length and breadth. In a set with a chain, as a rule, a special shaft is purchased, with a pointed end. It is intended to simplify installation, after pressing the axis, this end should be broken with pliers. Next, pass the chain through the tensioning rim of the switch, do not confuse the assignment, the lower chain roller flows on the left side, and the outer one on the right.

    We collect open links, put the shaft. We introduce the element into the chain squeeze and fix it with a screw. By twisting the squeeze handle, press the shaft into place, it must equalize the edges of the chain.

    Check that this element of the chain bends easily, if it goes hard, then you should correct the fishing line with squeeze. In this case, wedge the link into the second landing zone of the squeeze, in which case you can observe two ends of the axis.

    Tension adjustment on a single speed bike

    A properly tightened chain on a bike without gears must remain a little free for a sag value of approximately 5 millimeters.

    To put on a chain on an ordinary bike, you must:

    • Turn the vehicle upside down.
    • Loosen the screws or eccentrics of the back rail fastening.
    • Adjust the exact value of the chain slack by moving the spare wheel according to the oblique grooves, which are called dropouts.
    • It is only necessary to fasten the rear tire when its line is parallel to the carriage shaft.

    If the chain is too tight, it becomes very difficult to pedal on the bike, the elements of the chain transmission are instantly triggered. While the sagging chain can fly off the sprockets, and it will probably become impossible to drive further.

    If the spare wheel has previously rested against the border of the dropouts, there is nowhere to pull it down, and the chain strip is wobbling in the old way, in which case you will need to remove a couple of links.

    How to install and tension a bike chain

    The chain is considered to be one of the main useful components that ensure the movement is great. And the period of its work depends on the regularity and properties of the service. A sign of a chain malfunction is a crunch and squeak when moving, and in addition, slipping it on a ratchet.
