MR 20307 LLB - ABEC-5, Radial Bearing (C3 clearance) - 20mm x 30mm x 9mm -

This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, light-contact, dual-lip, labyrinth (LLB) seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.

This size bearing generally used as a front hub bearing, specifically for Mavic and Profile Racing. It is also used by Trek as a pivot bearing, though the MAX version is better suited for suspension applications.

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. 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 full labyrinth to provide long life and superior protection against the elements.
