Unlock faster rolling speed with the CeramicSpeed Bottom Bracket—built tough for mountain performance
What Our Gearhead® Experts Are Saying:
“I switched to a CeramicSpeed BB for my enduro bike and immediately noticed the free spin. It feels like less effort on every climb and absolutely zero creak, even after months of rough conditions. Totally worth it if you’re chasing performance and longevity.”
CeramicSpeed’s Mountain Bottom Bracket takes the same low-drag ceramic technology trusted by WorldTour teams and reinforces it for off-road durability. Inside each anodized aluminum cup, precision-ground ceramic balls roll on hardened steel races polished to a mirror finish. Dual-lip seals and Long-Life Grease keep out grit, dust, and water even after endless muddy rides.
Each variant—BSA, PF30, BB30, BB92, or T47/73—fits its specific shell type with exacting tolerances, maintaining alignment under the stress of big hits and pedal loads. Spindle options cover Shimano 24mm, SRAM DUB 28.99mm, and 30mm axles, making it compatible with nearly every modern crankset.
Coated bearing options add an extra defense against corrosion and micro-pitting for riders who push deep into wet seasons or alpine conditions. Whether it’s a high-mileage XC bike or a full enduro build, the CeramicSpeed BB keeps your drivetrain turning free, quiet, and fast—ride after ride, season after season.
