CeramicSpeed PF30A SRAM GXP Movimento centrale rivestito, nero

The CERAMICSPEED COATED PF30a bottom bracket is a high-end model that is compatible with Sram GXP cranksets and ensures exceptionally smooth movement and outstanding durability with its ceramic bearings. Designed with the utmost care and the best materials, this housing contributes to the stiffness of the pedal stroke. The bearing is coated with an ultra-thin (2-3 micron) protective layer that is 75% harder than hardened steel while remaining flexible. This reduces friction and at the same time increases resistance to water, salt, dirt and other foreign bodies.
