CeramicSpeed PF30 Bottom Bracket for SRAM GXP Road Coated Black

The CeramicSpeed PF30 bottom bracket for SRAM GXP Coated has the 68 mm wide cups as BB30, but they have a larger diameter, 46 mm, so the bearings in the cups can fit inside the hull. This kit contains all the parts you need to install a Quarq or SRAM 24 / 22mm spindle crank on a BB30 or cyclocross road bike. The package comes with two cups and CeramicSpeed bearings installed. There are two options Standard and coated. Both have super-soft CeramicSpeed balls mounted on hardened steel races. The coatings have an additional feature: a metal layer 3 microns thick on the strokes. This addition makes running smoother and harder, reducing drag and increasing life.The cups have extended sleeves, are connected via a spacer tube, which reduces the likelihood of creaking and increases reliability, and protect the internal 24/22 mm connecting rod wiring in the SRAM and Quarq connecting rods. Standard bearings have a friction cost of 0.3-.
