# FAQ: How Do You Count The Links On A Bicycle Chain?

## How do you calculate chain links?

Chain Sizing by Equation

1. 1/8″ = 0.125″
2. 1/4″ = 0.25″
3. 3/8″ = 0.375″
4. 1/2″ = 0.5″
5. 5/8″ = 0.625″
6. 3/4″ = 0.75″
7. 7/8″ = 0.875″

## How long is a 116 link bike chain?

One link is two pin-to-pin dimensions. Each pin is 1/2″ from its neighbor, so a full link is 1″ long. When they say the chain is 116 links, they are really saying there are 116 pins, for a chain length of 58 inches.

## What is a bicycle chain link?

The master link is a single removable link segment of a bicycle chain. You’ll hear people also refer to these as quick links. Also, SRAM’s version of the master link is called a Power Link. It is sold separately as well as typically included when you buy a SRAM chain.

Yes the master link counts as the last link so that if you want a chain of 110 links then cut it so the chain without the master link has 109 links.

## How long is a 520 chain link?

D.I.D 520 Standard Series Chain – 110 Links, Chain Type: 520, Chain Length: 110, Color: Natural, Chain Application: All 520 x 110.

## How do you calculate chain?

Procedure

1. Calculate C, where C = CD/p.
2. Calculate A, where A = Z1 + Z2.
3. Calculate S, where S = Z2 – Z1.
4. Refer to the adjacent table to find the T value for the calculated S value.
5. Chain Length in Pitches, CL = 2C + (A/2) + (T/C)

## How many links should my chain have?

A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.

## What size chain is on a bicycle?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

## How can I tell if my bike chain is stretched?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

## What is chain stay?

the chain stay is the part of the frame thats nearest to your chain, and often gets big gashes in it from your chain hitting it. often people have something covering there chainstay to protect it from the chain hitting it.

## How long is a link?

In US customary units modern definition, the link is exactly 66⁄100 of a US survey foot, or exactly 7.92 inches or approximately 20.12 cm. The unit is based on Gunter’s chain, a metal chain 66 feet long with 100 links, that was formerly used in land surveying.
