BB30 Outboard ABEC-3 Threaded Bottom Brackets

No More Creaking, Smooth Operation, Fast Bearing Replacement

The Wheels Mfg BB30 Outboard ABEC-3 Bottom Brackets are thread-together bottom brackets for BB30 frames.

Two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.

Choose from 24.00mm spindle diameter cranks (Shimano, Etc.) or 22mm/24mm spindle diameter cranks (SRAM / Truvativ GXP).

Note: FSA MegaExo spindles can be between 24.00mm and 24.07mm in diameter. If your FSA spindle is 24.07mm, this BB will not work! You will need to swap the bearings with Wheels Mfg FSA 24.07x37 ceramic hybrid bearings.
