Enduro ABEC5 MR 18307 LLB A5 Bearing

Giving military standard performance when it comes to strength and durability, this cycling-specific bearing utilises precision hardened Grade 5 Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races to offer a silent, higher tolerance than its ABEC 3 counterparts. Equipped with low contact rubber seals and Kyodo Yushi PS-2 grease this A5 model maintains a long-lasting and smooth performance.
