Collection: Bottom Brackets

The bottom bracket is the component that takes the most punishment on any build, and a poor fit or worn bearings will undermine an otherwise excellent drivetrain. Our range covers the main BB standards in use across road, mountain bike, and gravel builds, so whether you are running a 24mm axle crankset on a threaded shell, a BB30 press-fit frame, or need to upgrade worn cups with ceramic bearings, you’ll find the right solution here.

Our bottom bracket collection includes the Middleburn HT2 X-Type Bottom Bracket, compatible with any 24mm axle crankset, alongside Enduro ceramic bearing kits for both HT2 and BB30 applications. Enduro's ceramic kits offer reduced friction and longer bearing life over standard steel, and are a direct replacement for cups from Shimano, FSA, Truvativ, Hope, and Middleburn. We also stock a Cannondale-specific bottom bracket bearing kit for those maintaining Cannondale builds.
