Specific Applications
C-BEAR (Ceramic BEARings) Inner bearings are available with 2 different types of ceramic bearings. MTB/Cyclocross bottom brackets are designed for use in mud and on dusty roads. Special grease and seals make these bearings particularly suited for tough conditions.

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.
