At Kogel Bearings, they believe ceramic bearings set the gold standard for bottom brackets, derailleur pulleys and wheel bearings. The ceramic material used, Silicon Nitride, is hard and wear resistant, and will not rust or oxidize. It can be precision machined into perfectly round balls with super tight tolerances and polished smoother than any metal, making it perfect for bicycle bearings.
- Ceramic bearings provide optimum drivetrain efficiency.
- Precision machined components ensure a smooth, squeak-free ride.
- Bomb-proof, all-weather seals to keep you riding no matter what.
- High grade materials that guarantee long-lasting, low maintenance components.

This bottom bracket fits the M30 spindle of Praxis and InfoCrank on a BB30 frame.
The set consists of our BB30-386 bottom bracket with road or all-weather seals and a non-drive side reducer that will fit the 28mm stepdown of the 30mm Praxis spindle. This setup will space the bearings at maximum width, flush with the crank arms, to maximize your drive train stiffness and reduce bearing wear.
We recommend selecting all-weather seals, as these will withstand bad weather and any off-road cycling you might do. For your best bike, racing bike or fair weather bike, select the road seal for a marginal friction saving.
If you have any questions or doubts about the compatibility for your bike ask us and we will help you pick the right one - available 24 hours a day on the live chat, or at firstname.lastname@example.org.
