      PF30a Bottom Bracket for Shimano

      PF30a is a Cannondale-specific standard for their 73mm wide bottom bracket shells. This CeramicSpeed kit makes it possible to install Shimano and other 24mm diameter thru-axle cranks into a Cannondale frame.

      CeramicSpeed Bearings come installed in two cups and are connected through the shell via a spacer tube. There are versions with Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated have an additional attribute: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life.

      In The Box

      • 2 CeramicSpeed bearings pressed into cups.
      • 2 installed dust covers.
      • Spacer tube.
      • All Round Grease.
      • Sticker Sheet.

TECHNICAL SPECIFICATIONS

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.
