CH DRF 2941 LLB BO – Black Oxide, Ceramic-Hybrid, Double-Row, Flanged, Press-In Bottom Bracket Bearing solution for BB86/92 framesets and SRAM DUB cranksets – 29mm x 41/44mm x 11mm

This is a single bearing unit. One bearing is required per side of the bottom bracket. For the complete bottom bracket assembly, refer to BKC-7016.

You may find the following tools useful for installation:
• BRT-060-MH – Enduro Bearing Press rod and handle set
• BRT-040-29mm – Bottom bracket bearing removal and installation toolkit for 29mm bearings
• BRT-040-BB86/92 – BB86/92 adapter cup and puller for use with the BRT-040 toolkit
• GR-009 – Enduro MAX Bearing Grease

This custom-designed bearing allows you to run SRAM DUB 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 29mm 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.
