Enduro Bearing 2941/44-F 29 x 41/44 x 11 (DUB)
Description
DRF 2941 LLBO Double-Row, Press-In, Bottom Bracket bearing solution for BB86/92 framesets and SRAM DUB cranksets - 29mm x 41/44mm x 11mm -
Black Oxide
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 DUB 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. 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.
Stainless Steel
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.
Enduro stainless bearings all carry a full two year anti-corrosion warranty.
Ceramic Hybrid
This unique custom designed bearing allows you to fit SRAM DUB 29mm 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 29mm DUB 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.
XD-15
The ultimate upgrade
An Enduro Bearings exclusive, our XD-15 Ceramic-Hybrid bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup. The deep-groove design raceways allow for maximum sized Grade 3 Silicon Nitride ceramic balls for for increased contact area and improved performance and longevity. 90% fill Kluber NBU52 grease only runs better and smoother with time and is highly resistant to being washed out. Its engineered to stick to the balls and continually be pulled back into the ball path where it is needed.
Find out why Bike Radar reported the XD-15 "Hands down, the best bottom bracket we have ever tested". We are so sure that you will agree, that we offer an unlimited lifetime bearing and race warranty. The most impressive feature of these bearings is, unlike other bearings, they only get better with use. As the bearings wear-in, the balls actually make the races even smoother. So when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial advantages on day one, but will get even faster and smoother with time and use, while the other ceramic-hybrid options will only get slower.
This bearing is designed specifically for use in BB86/92 framesets with SRAM DUB cranksets.
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.
