About BikeCompat

What is this?

BikeCompat helps road cyclists quickly check whether components from different groupsets will work together. Select your current groupset and instantly see which chains, cassettes, derailleurs, shifters, and other components are compatible — no more digging through forum posts or manufacturer PDFs.

Data sources & accuracy

Compatibility data is based on published manufacturer specifications and established cycling community knowledge. Prices are indicative and may vary. Always verify compatibility with your local bike shop before purchasing — especially for bottom brackets, where frame BB shell type (BSA, PF30, BB86, T47) also matters.
