Enduro Bearings 61903 LLU/LLB CN A5 17x30x7 hub bearing

A radial bearing generally used as a hub bearing and can be used as a pivot bearing, though the MAX-type version of this bearing is better suited for suspension use.

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.

Enduro bearing are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with high pressure water proof grease for the ultimate protection against sweat and the elements.
