This custom-designed bearing allows you to run 30mm spindle cranksets directly in BB86/92 framesets. Due to the 41mm inner diameter constraint of BB86/92 bottom bracket shells, a specialized solution is required to accommodate 30mm spindles.

By utilizing double-row, flanged bearings that press directly into the BB shell, we maximize contact area and effectively double the number of balls per side, delivering a long-lasting solution in an extremely compact space. This ceramic-hybrid radial bottom bracket bearing features black oxide-treated 52100 high-carbon chromium alloy races, paired with Grade 5 silicon-nitride ceramic balls and 90% fill, high-pressure waterproof grease. Silicon-nitride ceramic balls roll smoother, reduce bearing wear, and increase bearing life by eliminating steel-on-steel contact within the bearing. The black oxide (magnetite) treatment adds an extra level of corrosion resistance for extended, worry-free performance.

All Enduro Zero (CO) and ceramic-hybrid (CH) bottom bracket and hub bearings are covered by a limited two-year warranty against corrosion, wear, and manufacturing defects.
Semi-annual professional servicing is required using Enduro Speed Bearing Grease (GR-011).

This bearing is designed specifically for BB86/92 framesets and cranksets with SRAM DUB cranksets.

The Enduro line of bearings is available in high-carbon chromium steel, black oxide-treated, 440C stainless steel, ceramic-hybrid, and ceramic-hybrid with XD15 super stainless steel races. Our bearings are engineered with the deepest groove races possible to accommodate larger balls and feature dual-lip seals that ride in a micro-groove, creating a full labyrinth seal for long life and superior protection against the elements.
