## What is chain length chemistry?

For any chemical chain reaction, the chain length is defined as the average number of times that the closed cycle of chain propagation steps is repeated. It is equal to the rate of the overall reaction divided by the rate of the initiation step in which the chain carriers are formed.

## When should I shorten my bike chain?

Ideally, you want to shorten your replacement chain after threading it through the chainrings and cassette. This makes it easier to determine how long your chain needs to be. Before threading the chain, however, check whether there are signs of extreme wear on the chainrings and cassette on your bike.
