Kogel 386EVO Corrosion Resistant Bottom Bracket Cross / 24mm/SRAM GXP

When every watt counts, the 386EVO Bottom Bracket gives smoother operation, better efficiency and higher speeds with every pedal stroke, along with exceptional durability, especially in wet conditions.

Built by hand in Texas, it features Kogel's new Kogel CR bearings, built with Kogel's premium ceramic balls, which are more symmetrical with stricter tolerances than steel ones, and proprietary hardened stainless steel races. Stainless steel is typically softer than carbon steel but to counter this Kogel has made its stainless steel 20% harder, to bring bearings made with the material in line with the brand's carbon steel ones.

This results in lower friction, more efficient power transfer and a smoother ride, as well as inbuilt corrosion resistance that won't wear the way a coating would. The result of two years of development, the custom stainless steel race has been specifically treated and hardened to last, with consideration to the rigours a wet weather 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 that keep grease in and the elements out. 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.
