BLACK BEARING PressFit 30 Eje Pedalier SRAM GXP

Ride with the highest quality thanks to the BLACK BEARING PF30-compatible bottom bracket and for cranksets with a 24 mm axle and the Sram GXP 22-24 mm type thanks to an adapter disc supplied. It is based on a lightweight, robust and extremely durable CNC-machined aluminium material. This model uses two-piece BBlock technology, which allows better alignment of the housing to ensure fewer cracks, longer bearing life and easier bearing replacement. B5 bearings are used, which are characterised by optimum reliability, exceptional fluidity and very high durability. These bearings consist of chrome steel balls, a cage also made of chrome steel and reinforced 2RS seals that ensure excellent resistance to water and dust.
