A strong and durable bearing that's tailored specifically for the demands of cycling.
The ABEC 3 MRA 2437 raises the bar for military standard, high precision bearings. Featuring HRC-64 hardened Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races, this model operates without any noise. The stunning ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of this bearing.
Kyodo Yushi PS-2: This grease has a protective interface between ceramic balls and metal races and for it’s high speed properties and minimum rolling resistance. Speed and Protection for high precision bearing systems.
LLB Seals: Two NBR 70 rubber seals with low contact seal, which rides in a matching groove machined into the bearing for low drag or friction.
