## How do I know chain size?

To determine the pitch (chain size), you’ll need **to measure the distance between any three consecutive rivets, then divide the result by 2**. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.

## What size is a 520 chain?

Metric Dimensions

Chain | Pitch | Roller Diameter |
---|---|---|

420 | 12.70mm | 7.75mm |

428 | 12.70mm | 8.51mm |

520 | 15.88mm | 10.16mm |

525 | 15.88mm | 10.16mm |

## What’s the difference between a 520 chain and a 530 chain?

A 520 chain is a smaller pitch chain. Pitch being the distance between rollers. The **520 is a lighter weight chain than the 530**. That is why people switch to the 520, but it may not last as long as a 530.

## How do I know which chain to buy for my bike?

How do I choose? Bike chain selection is **firstly decided based upon the “speed” of the chain**; this is because it determines the width of the chain. An 11 speed chain for example is narrower than a 9 speed chain, as the sprockets on the 11 speed cassette have a narrower spacing between them.

## How can you tell the difference between a 520 and 525 chain?

The 5 part just describes the distance between the centers of the link pins (or wherever on the links, basically how long a link is) and the next two numbers describe the width of the chain. So a **520 chain is going to be narrower than a 525**(and thus require a narrower front and rear sprocket) and lighter…

## What does 520 mean on a chain?

(3) The size of a **chain** is designated by a three-digit number (520, for example). The distance from the center of one pin to the center of the next is called pitch. Pitch is represented by the first digit, which is 4, 5 or 6.

## Will a 520 chain fit a 525 sprocket?

A **525 chain may run on 520 sprockets**, but a 520 chain is too narrow to run on 525 sprockets.

## Whats the difference between 525 and 530 chain?

**530 is heavier than 525**, which is heavier than 520. And with that the thicker ones are usually stronger.

## Will a 530 chain fit a 520 sprocket?

A 530 chain on a 520 sprocket **will work just fine**, a 532 will not. The differance between a 520 and 530 is the width, the roller diamiter and pitch are the same.

## How much power can a 520 chain handle?

That chain has a rated tensile strength of **8,800** and is rated for up to 1000cc bikes.
