What type of chain Does my bike need?

What kind of chain do I need for my mountain bike?

Chains from most manufacturers should fit, as long as the chain is made from good quality material and matches the number of sprockets in your bike’s rear cassette. Some mountain bikes have 9, 10, 11, and sometimes even 12 sprockets in their rear cassette, and length of chain for each of these bikes will be different.

How do I know my chain size?

To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.

How do I know if my bike chain is too short?

If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.
