About this collection
Rear sprockets
Rear sprockets from Sitta, CNC Racing, Spider Racing and K-Bike — ergal aluminium for racing lightness, steel for road lifespan, in the tooth counts that let you tune your gearing corner by corner.
Two teeth more on the rear shortens gearing noticeably — stronger drive off corners, livelier response, slightly busier motorway cruising. Ergal sprockets are trackday-light but wear faster; steel lasts several chain lives. Match the sprocket to your carrier's bolt pattern and your chain's pitch, both listed on every product.
