The C-BEAR PF30 SRAM DUB Race bottom bracket features ceramic bearings for smooth, quiet and efficient running. It is therefore particularly suitable for use in Road cycling. Only use it with the matching SRAM cranks with 28.99 mm axle diameter and install them in PF30 Road frames.
Application: Road Type: Pressfit PF30 Shell Diameter: 46 mm Shell Width: 68 mm Axle Diameter: 28.99 mm (DUB)
Bearings: ceramic Bottom Bracket Cup Material: aluminium
– SRAM DUB (Eagle, Eagle AXS, Red eTap AXS, Force eTap AXS)
– Race version, designed for driving on dry, clean roads – very efficient, low rolling resistance – CNC machined bearing cups
Specific Applications C-BEAR (Ceramic BEARings) Bottom brackets are available with 2 different ceramic bearing types. The Race bottom bracket bearings are designed for low rolling resistance and are intended for use on dry roads. In a study carried out by the independent Friction Facts Laboratory, they were ranked top 3 in terms of bottom bracket efficiency (the first place went to an unsealed bottom bracket for indoor use).
High Quality Bearing Cups The bearing cups of the C-BEAR bearings are not made of plastic, but of CNC precision machined aluminium. C-BEAR committed itself to an anti-plastic posture very early on, in 2011/2012, when plastic additives were just coming into fashion. Metal housings mean higher accuracy, lower tolerances and the avoidance of flex and deformation.
