Ride with superior quality thanks to the BLACK BEARING bottom bracket compatible PF30 and for cranksets with a spindle of DUB from the brand Sram.

It is built around a lightweight, robust and highly resistant CNC-machined aluminium material. This model uses the BBlock technology screwed in 2 parts for better bottom bracket alignment, resulting in less creaking, longer bearing life and easier bearing replacement.

It uses B5 bearings offering optimal reliability, exceptional smoothness and very high durability. These bearings consist of chrome steel balls, a chrome steel cage, and reinforced 2RS seals guaranteeing excellent resistance to water and dust.
