Kogel Bearings believes that ceramic bearings are the gold standard for bicycle bottom brackets, which is why they only offer podium-grade ceramic bearings in all their products. These silicone nitride bearings are hard, resistant to wear, and can be made into perfectly round balls with super tight tolerances and a low-friction polished finish. On top of that, ceramic bearings do not rust or oxidize, so if properly serviced they can last a really long time. The Kogel Bearings BB386EVO Bottom Bracket takes advantage of all these benefits, and is designed to fit any road bike frame with a BB386EVO shell. It comes in two versions, one for SRAM DUB spindle interfaces, and one that will fit both Shimano 24mm spindles and SRAM GXP stepped spindles.
