Ride smoother and longer with the CeramicSpeed Bottom Bracket—gravel-tough ceramic efficiency
What Our Gearhead® Experts Are Saying:
“I use the CeramicSpeed Gravel BB on my all-road rig, and it’s unreal how quiet and smooth it stays, even after hundreds of miles in the rain. The extra sealing really works—no grit, no grind, and zero maintenance headaches.”
Every gravel mile grinds on your drivetrain, but CeramicSpeed built this bottom bracket to fight back. Each variant—whether T47, BSA, PF30, BB86, Italian, or EVO386—houses hand-assembled ceramic bearings inside anodized aluminum cups, perfectly aligned for zero side load and minimal drag.
The Gravel Edition steps up protection with tighter dual-lip seals and Long-Life Grease designed to resist water and fine dust. These upgrades keep the bearings running smooth deep into multi-day events and wet-season training blocks. Each version pairs seamlessly with Shimano 24mm, Campy Pro Tech, SRAM DUB 28.99mm, or 30mm spindles, covering nearly every gravel frame standard in use today.
Coated versions add a final layer of armor, preventing corrosion from sweat and moisture while delivering that trademark CeramicSpeed spin. From washboard backroads to 200-mile races, this is the bottom bracket we trust when the elements test our resolve.
