ENDURO BEARINGS DRF 3041 LLB BO

DRF 3041 LLB BO - ABEC-3, Black Oxide, Flanged, Double-Row, Pressfit, Bottom Bracket Bearing solution for BB86/92 framesets and 30mm cranksets - 30 x 41/44 x 11mm - This unique custom designed bearing allows you to fit cranks with 30mm spindles 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 30mm 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. This ABEC-3 radial bottom bracket bearing features black-oxide treated 52100 High-Carbon Chromium alloy races paired with grade 10 Balls with 90% fill, high-pressure, water-proof grease. Black oxide/Magnetite treatment provides an extra level of corrosion resistance for extended worry-free performance. This bearing is designed specifically for BB86/92 framesets and cranksets with 30mm BB spindles (BB386 andB30). Enduro
