61806 LLU/LLB - ABEC-5 Radial Bearing (CN Clearance) - 30mm x 42mm x 7mm Radial Bottom Bracket Bearing featuring 52100 High-Carbon Chromium alloy races paired with grade 5 Balls with 90% fill, high-pressure, water-proof grease. Designed specifically for bicycle applications, the LLU/LLB seal combination on these bearings utilizes a more protective gray LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) black LLB seals facing inward keep the grease where it belongs. The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert MR 2437 is the correct bearing for the job 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.

6800 LLB - ABEC-3 Radial Bearing (C3 Clearance) - 10mm x 19mm x 5mm Radial bearing generally used as a hub bearing for some quick-release hub designs, pedals and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, dual-lip labyrinth (LLB) seals to withstand daily abuse of use and the elements, and to contain the 90% fill Mobilux NGLI 2 high pressure water proof synthetic grease. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls.

CXD 6806 LLB - ABEC-5, XD15, Ceramic-Hybrid, Radial Bearing - 30mm x 42mm x 7mm An Enduro Bearings exclusive, our XD15 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. It is 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 XD15 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 XD15 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. The most common use for this bearing is as an upgrade replacement bearing for BB30 and BB386 Cranksets with 30mm 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 and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
