SRAM PressFit 30 Ceramic Bottom Bracket – High-Performance BB30 PressFit for 30mm Spindle Cranksets
The SRAM PressFit 30 Ceramic Bottom Bracket combines the best features of both BB30 and PressFit bottom bracket systems, delivering superior performance, smoother pedaling efficiency, and extended durability for road and mountain bikes. Engineered for maximum drivetrain efficiency, this ceramic bearing bottom bracket offers reduced friction, improved power transfer, and longer bearing life, perfect for competitive riders and cycling enthusiasts alike.
Unlike traditional BB30 bottom brackets where bearings sit directly in the frame, the SRAM PressFit 30 system features precision-machined nylon cups that house the bearings, providing additional protection and easier installation. The integrated seals are pre-installed into the cups, effectively shielding the ceramic bearings from contaminants and ensuring smooth operation in all riding conditions.
Designed for 30mm spindle cranksets, this PressFit 30 bottom bracket requires a 46mm inner-diameter bottom bracket shell, with a width of 68mm for road bikes and 73mm for mountain bikes.
