Frequently Asked Questions

Q: Should I replace my chain when I replace my sprocket?
A: Yes. It is standard practice to replace the chain and both sprockets as a set. Putting a new sprocket on an old, stretched chain will cause premature wear on the new teeth.

Q: How do I know if my sprocket needs replacing?
A: Inspect the teeth regularly. If they look "hooked," pointed, or are beginning to bend, the sprocket has reached the end of its life and needs to be replaced to prevent chain failure.

Expert Pro-Tip

Expert Pro-Tip: When installing a new rear sprocket, always use a thread-locking compound (like blue Loctite) on the sprocket bolts. Vibration on these vintage bikes is significant, and you want to ensure those bolts stay torqued to spec. Also, double-check your chain alignment; even a slight misalignment will destroy a brand-new steel sprocket in just a few rides.
