Wheels Manufacturing's PF30 "Press Fit" Outboard Bottom Bracket will give you all of the same benefits as their well-loved Outboard style bottom brackets. The two machined aluminum cups 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.

Enduro Angular Contact Bearings:
In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Wheel play can be adjusted out of the hub, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely.

Grade 10 Chromium Steel Balls:
High precision balls are within 10/1,000,000" round, twice as round as the industry standard, at its highest level. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

The above WMF was installed. I went for a 20 Miles Bike test.

This PF 30, BB, works well, the Angular Bearings are smooth
and quiet. Now all I hear is tire noise.

I would like to thank Bike Nasbar for, their excellent customer
