ENDURO BEARINGS DRF 2941 2RS SS

DRF 2941 2RSS - Stainless-Steel, Flanged, Double-Row, Press-In, bottom bracket bearing solution for BB86/92 framesets and SRAM DUB cranksets - 29mm x 41/44mm x 11mm - This unique custom designed bearing allows you to fit SRAM DUB 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 the SRAM 29mm 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 bearings feature 440C stainless steel alloy races and balls with 90% fill, high-pressure, water-proof grease. Not all stainless steel is created equal.¨ Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. This bearing is designed specifically for BB86/92 framesets and cranksets with SRAM DUB cranksets. Enduro
