ENDURO BEARINGS 61806 LLU / LLB

Enduro 61806 LLU/LLB - ABEC-5 Radial Bearing (C3 Clearance) - 30mm x 42mm x 7mm - ABEC-5 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 bicycle applications, the LLU/LLB seal combination on these bearings utilizes a more protective LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) LLB seals facing inward keep the grease where it belongs. The most common use for this bearing is as a direct replacement bearing for BB30, PF30, BB386 and most other bottom brackets with a 30mm OD spindle. Enduro
