Taking SCARY out of used bikes, one bike at a time.
All Cracked Up!
Should I replace this if the teeth of the pulley are still good?
Unfortunately, the spacing between the teeth has been compromised, and the chain will not match. Not replacing it may cause poor shifting and possible damage to other components.
Pulleys are not that expensive and easy to replace in most cases.
