C-Bear Ceramic PF30 MTB/Cyclocross Bottom Bracket (SRAM GXP,Truvativ)

Why C-Bear
C-Bear are ceramic bearing specialists, they focus on what they know best. All their products come standard with ceramic bearings, the ultimate when you want less friction, longevity and affordable pricing. All C-Bear bottom brackets are housed in aluminium, there is no plastic here. Metal alloy housings have almost no flex, do not deform, and are made with higher precision and tighter tolerances. By placing the ceramic bearings directly next to the crank arm, optimal stiffness and maximum power transfer is achieved.
C-Bear KISS
"Keep it simple and straightforward" is C-Bear's motto. C-Bear does away with spacers, rings and wave washers. There is no need to worry about what goes where, how thick they have to be or in what sequence. C-Bear does all the thinking and eliminates all the unnecessary parts. Simply install and ride. No creak, no loctite, simply working as it should, just silent speed performance.
One Size Does Not Fit All
With a full array of bottom brackets, C-Bear has a bottom bracket to suit your frame and crank combination, with no spacers or adapters. C-bear differentiates and offers 2 types of ceramic bearings. Race bottoms brackets have the least rolling resistance and are best suited to dry road conditions. Cyclocross/MTB bottom brackets are for riding through puddles and on dirt roads, as they use a specially formulated grease with seals designed to cater for these riding conditions.
