M2 600 Mini Sprint Sealed Front Hub Bearing.
Fits Keizer, Weld and Joes Front Hubs.
The M2 process introduces a treatment to metal surfaces to reduce friction and drag, enhance oiling capabilities, and prolong life. M2 bearings begin as the highest quality Superior bearings. After adding the M2 treatment, all sealed bearings are repacked with DAYLube™ NanoCeramic Racing Grease.
Very little amount of grease is needed for these bearings. DAYLube™ NanoCeramic Racing Grease is highly recommended for this product as it does not fling off and is compatible with the treatment.
