Silicon nitride ceramic bearings for bicycle hubs and bottom brackets. Hand-graded. Coated races. Built for riders who measure watts, not just miles.
The best ceramic bearings shouldn't cost as much as a wheelset. SpinForge focuses on two things: hub bearings and bottom brackets. The two applications where ceramic delivers the most measurable performance gain. No oversized pulley wheels. No headset bearings. Just the components that actually make you faster, built with the same silicon nitride and hardened races as the premium brands.
Complete ceramic hybrid bearing sets for Shimano, DT Swiss, Zipp, ENVE, Roval, Campagnolo, and more. The upgrade you feel on every ride.

Included with every kitHeavy-duty seals for gravel, rain, and year-round riding. Because Florida thunderstorms don't check your training schedule.
Available separatelyThe same material used by CeramicSpeed and Kogel. Harder than steel, smoother surface finish, virtually frictionless at cycling RPMs.
Cheap ceramics skip this step. We don't. DLC-coated steel races resist the harder ceramic balls, extending bearing life by years.
Tighter tolerances mean less play, less vibration, and more efficient power transfer from your pedals to the road.
Choose road or cross seals for your riding conditions. Switch them when the seasons change. One bearing, two personalities.
SpinForge is building ceramic bearings for the riders who take performance seriously but refuse to overpay for a logo.
