What fits your bike?
Find your bike and see which brake pads and cassettes fit it — worked out from the parts it ships with and checked against the manufacturers' own compatibility tables. When we don't know, we say so instead of guessing.
Know the part instead? Pads by caliper · Cassettes by freehub body

Or start from the part you have
Pads fit by caliper, not by bike, and a cassette fits by freehub body and speed count. Each page lists what fits and the bikes that ship with it.
Then save it. We'll keep track.
You don't own just one bike, you own a quiver. Save yours and the answers follow the bike you actually ride, swapped parts included.
Save it to your quiver
Paste a link to your bike's page and we fetch the build — frame, fork, drivetrain, brakes, wheels. The answers then follow the bike you actually own, upgrades included.
Get reminded
Log a service and set a reminder. When it's due we tell you in the app and by email.
Share it with your shop
Hand your mechanic a link or QR code with the full build and service history. No more twenty questions at the counter.
Sell what you're not riding
List a bike or a part to riders who know what it's worth. Buyers message you through the site; your email stays private.
Keep a parts bin
The takeoff bar, the spare cassette, the wheelset in the rafters — tracked, not lost. Keep the old part when you swap one on.
See what riders run
A public gallery of real builds and what people changed on them. Yours gets a page of its own.
