Collection: BMX Seat Clamps

BMX seat clamps hold the seat post in the frame, with bolt-on and quick-release options across freestyle, race, retro and smaller-frame setups. Blue Groove also carries replacement clamp bolts and hardware for compatible integrated systems.

Match the clamp to the outside diameter of the frame’s seat-tube area, not just the seat-post size. Check the existing clamp or frame specification before ordering, and if you’re replacing only the bolt or barrel, make sure it matches the original clamp system rather than assuming the hardware is universal.
