The Wheels Manufacturing Outboard Bottom Bracket comes with two machined aluminum 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.
The bottom bracket is designed for frames with a 68-73mm wide BB30 bottom bracket shell and 24mm cranks spindles. It comes with outboard Enduro Zero Ceramic sealed bearings for almost no friction and no wear. They offer a ultra smooth and quiet run and are protected against corrosion while using the roundest balls you can get without a military license.
