A radial bearing generally used as a hub bearing. 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. Enduro's 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.

A bit of an oddball size, this bearing generally used as a front hub bearing, specifically for older WTB 20mm hubs. It has also been used for Isis bottom brackets.
