# How many links are in a stealth bike chain

For a road bike, the 3rd method is usually used for calculating the size of the bike chain. This is a technique where the chain is installed on a small sprocket in the back and a large one in front.

## How to find out how many links are in a chain?

There are two methods to count the number of links.

• Count all the outer links together with the lock, and then multiply by 2. It is possible, of course, to count the inner links, but this is not very logical.
• Count all pins (their number must match the number of links).

## How to find out for different types of bicycles?

### For singlespeed (single speed bike)

To choose the length of the bicycle chain for a single speed or a bicycle equipped with a planetary hub, it is necessary to install the latter in the suspension bracket of the frame (dropout) so that in the future, as the bicycle chain is stretched, it will be possible to move it back.

Attention! When replacing a factory chain with a new one, it is imperative to count the links in the factory sample. In the new chain, if necessary, it is necessary to leave the same number of them as the original.

## Basic sizing methods

There are two key tricks for determining a parameter such as chain length.

• The most important thing is to install it on a large sprocket in the transmission system, at the same time it is necessary to install it on the smallest sprocket in the rear sprocket system (also known as the rear cassette). Then you need to pass it through the rear derailer (this is the name of the derailleur). After completing this work, tighten it so that the axle that passes through the center of the rollers of the rear derailleur is in an upright position. If the correct chain tension has been performed and it turns out to be longer, a certain amount of extra links will form at the connection section of the 2 ends. They can be easily removed by adjusting the chain length at the same time to fit your own bike.
• The next method actually mirrors the sequence of steps of the previous method. That is, mount the chain on the smallest sprocket in the transmission system and the same sprocket in the rear sprocket system. At the same time, there should be a slight tension on the chain, that is, the bike chain should not be loosened. It follows that unnecessary links may also remain in the junction area, which must be removed.

It should be further noted that in determining the optimal length of the bicycle chain, you can practice the first and second methods simultaneously. If in both versions the same number of unnecessary links came out, then it means that you can safely remove them.

When the number is different, then it is worth checking again, since it may be that a mistake was made in some of the options. If you remove the wrong number of links, there is a risk of getting a chain that is too long or too short. In such situations, driving on two-wheeled vehicles is risky, and the degree of reliability of the bicycle chain will significantly decrease.

### For mountain bike and bike hybrid

There are three main calculation methods when it comes to mountain bikes and bicycle hybrids.

• Throw the chain over the largest sprockets at the back and front of the bike, pull the rear derailer leg to the maximum, so that it moves forward while doing this. this will be the ideal size for the bike chain. It should come out like this: the derailer’s body will be practically in line with the paw (this is the maximum, further. failure). Please note that it is recommended to install the foot at a slight slope.
• As in the previous version, the chain is thrown onto the largest sprockets without involving the rear derailer. We write down or remember the required chain size, then add a couple more links to this parameter, and an acceptable length comes out. In principle, the output should be approximately the same as in the first method.
• Attach the chain in the front to the large sprocket and the smallest to the back and adjust the size so that the derailer’s foot is at right angles to the ground, i.e. the axes of the derailer rollers are under each other.

On a note! If you are the owner of a 2-outboard bike, then in this case it is necessary to measure the length of the chain with the shock absorber in a compressed state.

## Bicycle chain length: how to determine and choose the best?

Bicycle chain. links connected one by one with pins. It is intended to transmit torque. The efficiency is capable of reaching 98%. When installing a new chain on a bicycle, as a rule, it is necessary to correctly calculate its length or the number of links. A short chain can lead to problems if gear changes are made to large sprockets. Too long chain. will sag and jump off the sprockets on its own.

## Main selection criteria

Choosing the right chain depends on how many sprockets you have in your bike. If it is equipped with 5, then with this option, a typical version with a width of 2.4 millimeters will be suitable. When the conversation is about a bicycle with 6-7 sprockets, then you should choose more expensive and high-quality products, since typical products may simply not tolerate such loads, not to mention the degree to which this process must be taken seriously when purchasing a chain for a bicycle with 8 stars, because only the most flexible and expensive samples can suit him.

Of course, if desired, the use of cheaper analogs is also allowed, but then you will have to replace them quite often, moreover, it will most likely need to be done in conjunction with cassettes, which makes savings very unlikely.

over, the parameters of your old and new chains must match one hundred percent, and especially this concerns their width.

It is advisable to use a chain from the same manufacturer whose product you used earlier.

To choose the length of the bicycle chain for a single speed or a bicycle equipped with a planetary hub, it is necessary to install the latter in the suspension bracket of the frame (dropout) so that in the future, as the bicycle chain is stretched, it will be possible to move it back.

Attention! When replacing a factory chain with a new one, it is imperative to count the links in the factory sample. In the new chain, if necessary, it is necessary to leave the same number of them as the original.

For road bikes, there are usually 3 ways to determine chain length. This is a method in which the chain is placed on a large chainring and a small rear.

## Bicycle chain main dimensions

A bicycle chain is made up of links. The standard distinguishes between internal, external link and their connection. Modern chains can be used on almost all types of bicycles. There are separate specialized types for multi-speed bikes.

Many people make chains with chamfers, which speed up the gear change process. When using a chain from the same manufacturer on different types of bikes, it will behave and wear differently. When choosing a suitable chain, you should pay attention to the main dimensions, of which there are 3.

### Bicycle chain pitch

This is the distance between two pins (elements connecting two half-links). According to the standard, this step is ½ inch or 12.7 millimeters.

### For mountain bike and bike hybrid

There are three main calculation methods when it comes to mountain bikes and bicycle hybrids.

• Throw the chain over the largest sprockets at the back and front of the bike, pull the rear derailer leg to the maximum, so that it moves forward while doing this. this will be the ideal size for the bike chain.

On a note! If you are the owner of a 2-outboard bike, then in this case it is necessary to measure the length of the chain with the shock absorber in a compressed state.

### The number of links in the bicycle chain and its working length

The length of a bicycle chain is determined by the number of links that make up the chain. For example, spare parts chains designed to work with a 12-speed cassette are 126 alternating inner and outer links in length.

For a complete set of bicycles, chains are supplied in lengths of 108, 110, 112, 114, 116, 118, 120, 122, 124, 126 links.

Bicycle chains that come with parts are usually 114 or 116 links. The number of links depends on the manufacturer’s approach. Many bicycle chain manufacturers supply their chains with a special detachable link. the chain lock.

The number of links 114 or 116 may be excessive. Different types of bicycles require different working chain lengths. The working length of the chain is achieved by removing excess links.

For MTB mountain bikes, the chain usually has to be shortened to 106-108 links. This chain length is due to the size of the stars in the system and the length of the back feathers.

For bicycles with long rear stays, such as some 29ers, the chain is shortened to 112 links.

For certain types of bicycles, such as road bikes, the chain can be skipped and used out of the box.

When replacing the factory chain with a new chain, be sure to calculate and record the number of links in the factory chain. In new chains, if necessary, leave the same number of links as the factory chain.

## How to find out how many links are in a chain?

There are two methods to count the number of links.

• Count all the outer links together with the lock, and then multiply by 2. It is possible, of course, to count the inner links, but this is not very logical.
• Count all pins (their number must match the number of links).

### Bicycle chain pitch

All modern bicycle chains have a standard pitch of 1/2 ”or 12.7mm.

The pitch of the bicycle chain is equal to the distance between the pins see Fig. 3.

Conversion of fractional values ​​of inches to millimeters can be done using the Table of conversion of fractional values ​​of inches to millimeters

### For mountain bike and bike hybrid

### Bicycle chain width or pin length

The overall width of the bike chain is determined by the pin size. The designers design the width of the bicycle chain based on the width of the cassette and the number of stars in it.

There is a clear trend towards a decrease in the width of bicycle chains, while the number of stars in the cassette increases.

## Main selection criteria

Choosing the right chain depends on how many sprockets you have in your bike. If it is equipped with 5, then with this option, a typical version with a width of 2.4 millimeters will be suitable.

over, the parameters of your old and new chains must match one hundred percent, and especially this concerns their width.

It is advisable to use a chain from the same manufacturer whose product you used earlier.

It should be noted that additional marking is applied to individual samples according to the quality of their manufacture, and, as a rule, it is in the form of numbers. Accordingly, the higher the number of the marking, the better the product. Additionally, it should be said that chains often differ in their color, and the best samples are painted exclusively in the color of gold.

### Bicycle chain width

The width can be determined by measuring the pin size. All chains have different widths, and it is determined depending on their purpose. There is a tendency for the number of sprockets on a multi-speed bike to be inversely proportional to the pin size.

The approximate ratio of the number of stars (pcs.) To the width (mm.):
