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.
- ROTOR 24mm
- SRAM GXP
This BB is supplied with a separate GXP washer, for compatibility with a Shimano, Sram GXP and Rotor 24mm crank on a BB86 (road) or BB92 (MTB) frame.
BB86 is the road standard: 86.5mm width, 41mm inner diameter.
BB92 is the mountain bike standard: 92 or 89.5mm width, 41mm inner diameter.
Although the crank and frame dimensions are slightly different, the bottom brackets are the same.
Usually found on Giant road bikes, among others.
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 email@example.com.
