Wheels Manufacturing Outboard Bottom Bracket

This model is designed for frames with a BB86/92 interface and a PF41 shell ID. It is compatible with shell widths of 86mm, 92mm, and 89.5mm, provided you are using a 24mm spindle crankset.

Angular contact bearings allow all the ball bearings to engage simultaneously, which spreads the load across a larger surface area. This design effectively reduces friction and minimizes wear, leading to smoother operation and greater durability.

Yes, the threaded design is specifically engineered to eliminate the creaking often associated with press-fit systems. By threading the two aluminum cups together, the unit creates a stable, secure interface that resists the movement that typically causes noise.

It is built for durability in harsh environments. The unit features LLB dual-lip groove seals that provide a robust barrier against water and dirt, protecting the internal bearings from contamination.

You will need a bottom bracket tool compatible with a 16-notch MegaEvo interface. This standard tool pattern ensures you can properly tighten the cups to the frame.
