The Wheels Manufacturing bottom bracket comes with two machined aluminum outboard cups which 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.
This bottom bracket is designed for frames with a 68-73mm wide bottom bracket shell and 24mm cranks spindles. It comes with Angular Contact bearings for less friction and minimized wear.
