BB30 bottom bracket with anodized cups and ceramic bearings for 68mm wide bottom bracket shells with a diameter of 42 mm and SRAM DUB cranks with 28.99 mm axles.
Super smooth, super round CeramicSpeed balls are rotating in hardened-steel races in both. In CeramicSpeed coated bearings the steel races are coated with an extremely thin (2-3 microns) protective layer, which is 75% harder than hardened steel. This metallic coating laid onto the races, making it even smoother and harder, resulting in longer life and lower drag.
