This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
This bottom bracket is designed for frames with a 86.5mm wide 386EVO bottom bracket shell and 30mm cranks spindles. It comes with Angular Contact bearings for less friction and minimized wear.
