C-BEAR BB86 Rotor 30 mm Gen2 Race Bottom Bracket 41 x 86.5 mm

C-BEAR BB86 Rotor Gen2 Race Bottom Bracket - For Rotor and other 30 mm cranksets

This BB86 bottom bracket from C-BEAR is used to install a crank with 30 mm axle, e.g. from Rotor, in a press fit road bike frame with 86.5 mm bottom bracket shell width. In the second generation, thanks to a widening of the right-side bearing cup, it manages to do without spacers at all. The bottom bracket has smooth-running, very low-friction and efficient ceramic bearings that work ideally on dry, clean roads. The bearing cups are made of aluminium.

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.
