Angular Contact Bearings:
Enduro produce a line of Angular Contact (A/C) cartridge bearings specifically designed for hubs. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Wheel play can be adjusted out of the hub, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely.
