CH DRF 3041 2RS | 30 x 41/44 x 11mm Press-In Bottom Bracket Bearing

CH DRF 3041 2RS - Ceramic-Hybrid, Flanged, Double-Row, Press-In, Bottom Bracket bearing solution for BB86/92 framesets and BB30 style cranksets 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 rolls smoother, reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. This bearing is designed specifically for BB86/92 framesets and cranksets with 30mm BB spindles (BB386 and BB30). 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 and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
