Wheels Manufacturing BB30 Bottom Bracket - Shimano


The Wheels Manufacturing BB30 Shimano Bottom Bracket features two machined aluminum cups that thread together ensuring the bottom bracket remains 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. Specifically designed for installing 24mm spindle diameter cranks (Shimano, FSA, Etc.) in BB30 frames (42mm ID BB shell) without the need for any adapters. Replaceable Enduro bearings. Made in the USA.
