Specs At A Glance

Good To Know

Q: How do I know when the front sprocket needs replacing? A: Worn, hooked, or pointed teeth and a chain that will not hold tension are the usual signs. Replacing the sprocket with the chain extends the life of both.

Q: Should the rear sprocket and chain be changed at the same time? A: It is best practice to replace the chain and both sprockets as a set so they wear evenly. Mixing new and worn parts accelerates wear on the new sprocket.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
