PF30 road bottom bracket shells are 68mm wide like BB30, but have a greater diameter of 46mm so that bearings in cups can fit inside the shell. This kit contains all the parts you need to install a Quarq or SRAM 24/22mm crank in a BB30 road or cyclocross bike.
The cups have extended sleeves and are joined via a spacer tube, reducing the likelihood of creaking and increasing the reliability, as well as protecting internal cables from the crank spindle. The bundle comes with two cups with CeramicSpeed bearings installed. There are two bearing choices: Standard and Coated. The both feature super-smooth CeramicSpeed balls fitted in hardened-steel races. The Coated have an additional feature: a 3-micron-thick metallic layer over the races. This addition makes the races smoother and harder, lowering drag and increasing life.
The Standard Bearings have a friction drag of 0.3-0.4 watts per set, an average drag reduction of 75% compared to stock BBs and the result of smart design, including hardened-steel races and ceramic balls that are 100% smoother and 15% harder than other ceramic bearings. They also last longer.
Coated Bearings feature an even longer service life and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our Standard.
All Round Grease is installed in the bearings. 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 the bearing when riding through messy conditions.
