Bottom Brackets

We carry a wide selection of bottom brackets from CeramicSpeed, Praxis, ROTOR, Shimano and SRAM. These bottom brackets fit a wide range of frames and cranksets. We also stock both steel and high-end ceramic versions.

Additional Bottom Bracket Info:


CeramicSpeed makes high-end bottom brackets for road, MTB and TT bikes. The company promises you the lowest friction and longest product lifetime of any bottom bracket on the market. They also offer special coated finish versions which feature a metallic layer that covers the bearing races and makes them 75% harder than steel. You get a lifetime warranty when you buy a CeramicSpeed coated product.


Praxis manufactures steel and ceramic bottom brackets for their tapered M30 spindle which uses a 30 mm drive side bearing and 28 mm non-drive side bearing. They also offer versions for 30 mm, 24 mm and DUB spindles. Their press fit bottom brackets require a specific socket tool as they use an elastomer collet for account for frame tolerance differences and provide better rigidity.


ROTOR makes some of our best-selling bottom brackets. They fit a variety of frames, work great and are reasonably priced. Most models are available in both steel and ceramic options. They feature durable bearings, silicone shields and are known to be smooth rolling and made to last.


We carry Shimano PressFit and threaded bottom brackets. Shimano BSA bottom bracket are compatible with English (BSA) threaded 68 mm road shells and 24 mm Shimano road cranksets. The Shimano DURA-ACE and Ultegra BB86 bottom brackets are compatible with BB86 and BB92 shells. Both bottom brackets feature reliable bearings and seals which gives them a long service life.


SRAM makes DUB bottom brackets to fit SRAM and Quarq road and MTB DUB cranksets. DUB cranksets use a unique 29 mm spindle and therefore require specific bearings with this internal diameter. We carry the four most common SRAM DUB BBs. If you need a version that you don’t see below, please contact us and we would be happy to order it for you.
