DRF 3041 LLB BO – ABEC-3, Black Oxide, Double-Row, Flanged, Press-In Bottom Bracket Bearing solution for BB86/92 framesets and 30mm cranksets – 30mm 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 BK-7018.

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 ABEC-3 radial bottom bracket bearing features black oxide-treated 52100 high-carbon chromium alloy races, paired with Grade 10 balls and 90% fill, high-pressure waterproof grease. The black oxide (magnetite) treatment adds an extra level of corrosion resistance for extended, worry-free performance.

This bearing is designed specifically for BB86/92 framesets and cranksets with 30mm spindles (BB386 and BB30).

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.
