PF30A is a Cannondale-specific standard for their 73mm wide bottom bracket shells. This CeramicSpeed kit makes it possible to install Campagnolo and Fulcrum Ultra-Torque cranks on PF30A Cannondale frames.
CeramicSpeed Bearings come loose for crankarm attachment and sit inside the included cups once mounted. There are versions with Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The 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.
The unique PF30A shell is 73mm wide with a 46mm diameter. Ultra-Torque cranks seat the bearings on the inside of the crankarms. A removal/installation tool is necessary; we sell one here, but any appropriate tool will work.
0.3-.04 watts of friction is the 'cost' of our Standard Bearings. That's a drag drop of 75% compared to stock bottom brackets. This is the result of great design: hardened-steel races combined with ceramic balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer.
Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% versus our Standard.
All Round Grease comes applied to the bearings from the factory. It can be replaced for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messy conditions.
