This unique custom designed bearing allows you to fit 30mm 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 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. 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 30mm BB spindles. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.Specifications:- Static load: 1702lbf / 7.57kN- Weight: 33.7g
