Kogel BB30 Bottom Bracket Cross / SRAM Dub

When every watt counts, the BB30 Bottom Bracket gives smoother operation, better efficiency and higher speeds with every pedal stroke, along with exceptional durability in real world conditions.

Built by hand in Texas, it features Kogel's high quality ceramic balls, which are more symmetrical, with stricter tolerances, than steel ones. The ceramic balls run on high grade, stainless-steel races, resulting in lower friction, more efficient power transfer and a smoother ride. They're made to last, using the best materials and refined assembly processes, with consideration to the rigours your ride will place on the bottom bracket.

The BB stands up to heavy use without deformation or lost efficiency and is crafted with a choice of specifically tailored seals. The road seals are engineered to offer the lowest possible resistance and reduce drag, allowing you to deliver your best performance without compromise.

The cross seals are built to protect against mud, dirt and water entering in the course of your MTB, gravel and CX ride, ensuring the bottom bracket will perform at its best, delivering silky smooth action and helping you to harness every watt, with long lasting performance and reliability. They lose just 0.5w compared with using the road seals on the bottom bracket.
