Conquer rough miles with the CeramicSpeed Bottom Bracket—smooth, sealed, and built for gravel
What Our Gearhead® Experts Are Saying:
“After a season of racing and training on this CeramicSpeed BB, I’m convinced it’s the quietest and most durable setup out there. Even after countless muddy miles, the spin is still buttery smooth, and I haven’t had to service it once. It’s the perfect balance of efficiency and protection for gravel.”
When the road turns to dust and the climbs get longer, we want every bit of efficiency we can get—and that’s why we trust the CeramicSpeed Bottom Bracket Gravel. Built in Denmark and engineered for rough conditions, this BB pairs low-friction ceramic bearings with reinforced seals and long-life grease to shrug off grit, water, and washboard abuse.
Each version is tailored to modern gravel frames—from T47 and PF30 to BSA, Italian, and BB86—and works with spindles like Shimano 24mm, SRAM DUB, Campy Pro Tech, or 30mm. The precision-machined aluminum cups ensure perfect alignment, while coated bearing options resist corrosion for season after season of reliable performance.
No creaks, no drag—just miles of smooth, efficient pedaling when the adventure heads off pavement.
