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 housings mean higher accuracy, lower tolerances and avoiding flex and deformation.
