Guolis Enduro Bearings DRF 3041 LLB ABEC 3 Black Oxide

DRF 3041 LLB BO - ABEC-3, Black Oxide, Flanged, Double-Row, Press-In, Bottom Bracket Bearing solution for BB86/92 framesets and 30mm cranksets - 30mm x 41/44mm 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).

The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating full labyrinth to provide long life and superior protection against the elements.
