C-BEAR BSA SRAM DUB Race Bottom Bracket

With this C-BEAR Road Race bottom bracket you can install a SRAM DUB crank in a BSA bottom bracket shell. Unlike the predecessor model, it comes with a bottom bracket centre tube that enables protected routing of cables and wires. The bottom bracket works very efficiently thanks to ceramic bearings, with extremely low rolling resistance. It is intended for use on the road.

Specific Applications
C-BEAR (Ceramic BEARings) Inner bearings are available with 2 different types of ceramic bearings. The Race bottom bracket bearings are designed for low rolling resistance and intended for use on dry roads. They placed in the top 3 for bottom bracket efficiency in a study by the independent Friction Facts Lab (with first place going to an unsealed bottom bracket for indoor use).

High Quality Bearing Cups
C-BEAR bearing cups are made of CNC precision-machined aluminium. C-BEAR adopted an anti-plastic stance as early as 2011/2012, when plastic additives were just becoming the norm in bottom bracket manufacturing. Metal housing means higher precision, lower tolerances and avoiding flex and deformation.
