On a classic Ahead headset bearing, the steerer bearing cone fits precisely into the high-quality Acros AH-44S headset lower. Encapsulated sealed angular contact ball bearings in the alumninium head bearing cup absorb the forces evenly in axial as well as radial direction. This allows for perfect steering movements. The plate-reinforced rubber sealing provides a durable grease film of the special sliding grease in the bearing base for reliable protection from dirt and water.
