PF30 road bottom bracket shells are 68mm wide like BB30, but have a greater diameter, 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 spindle crank in a BB30 road or cyclocross bike.
The bundle comes with two cups and CeramicSpeed bearings installed. There are two choices. Standard and Coated. The both possess 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.
