BLACK BEARING PressFit 30 Wspornik dolny SRAM DUB Ceramic

Ride with the highest quality thanks to the BLACK BEARING ceramic bottom bracket, which is compatible with PF30 and for DUB axle cranksets from SRAM.

It is based on a lightweight, robust and extremely durable CNC-machined aluminium material. This model utilises two-piece BBlock technology, which allows for better alignment of the housing for less cracking, longer bearing life and easier bearing replacement.

In addition, B5 bearings with Si3N4 ceramic balls with high fluidity and lightness and robust steel rings are used.
