CH DRF 2941 LLB BO - Black-Oxide Coated, Ceramic-Hybrid, Flanged, Double-Row, Pressfit, Bottom Bracket Bearing solution for BB86/92 framesets and SRAM DUB cranksets - 29mm x 41/44mm x 11mm -
This unique custom designed bearing allows you to fit SRAM DUB 29mm cranks directly into a BB86/92 frameset. With the limitation of just 41mm inner diameter of the BB86/92 bottom bracket shell, it requires a special solution to accommodate for a 29mm DUB BB spindle. By utilizing flanged double-row bearings that press directly into the BB shell, we are able to maximize contact area by doubling the number of balls per side to provide a long lasting solution in an extremely tight space. These Ceramic-Hybrid bearings feature 52100 High-Carbon Chromium alloy races paired with grade 5 Silicon-Nitride Ceramic Balls with 90% fill, high-pressure, water-proof grease. Sl-Ni Ceramic balls roll smoother, reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. Black oxide/magnetite treatment to the races provides an extra level of corrosion resistance and extended worry-free performance.
This bearings Designed specifically for BB86/92 framesets and cranksets with 29mm BB spindles.
