Enduro Bearings 61805 LLU/LLB A5 CN ABEC 5 radial 25x37x7 bottom bracket bearing

Radial bottom bracket bearing with 52100 high-carbon chromium alloy raceways coupled with grade 5 balls with 90% waterproof high-pressure grease.

Designed specifically for cycling applications, the LLU/LLB seal combination improves the performance and durability of these bearings. The more protective grey LLU seal faces outwards, towards the elements, to reduce contamination from water or dirt, while the black LLB seal on the inside of the bearing reduces friction and keeps the grease in place.

Enduro 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.

The most common use of this bearing is as a direct replacement for Shimano outer bearings when using the plastic cap. If you want to avoid using the plastic insert this bearing is the right one.
