If you replace your sprockets, you need to replace the chain along with it. If you swap out a sprocket (either because it is worn or because it's not the size you want) unless everything is brand new, you need to replace the chain and the other sprocket at the same time. Consider the sprocket and chain as a set.

If you are not sure what the sprocket tooth count is, check the old sprocket. It should be stamped.


Chains and sprockets are sized by the pitch which could be the distance from roller to roller on a chain or from point to point on a sprocket.

A chain and sprocket must have the same pitch for them to be compatible.
