The unique PF30A shell is 73mm wide, 46mm diameter. These cups and bearings adapt the shell so it is compatible with Shimano, FSA, and others.

0.3-.04 watts of frictional drag is the “cost” of our CeramicSpeed Standard Bearings. That’s a reduction in drag of 75% compared to stock bottom brackets. This is the result of great design: hardened-steel races combined with CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer.

The CeramicSpeed Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings.

All Round Grease comes pre-installed in the bearings. It can be replaced for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.
