ACB Bearings for Bicycle Headset
The headset plays a very important role in the function of the bike, contributing significantly to its function and performance. Steering maneuvers can have a big impact on the competition/race. We know that consistent, dependable, and smooth steering maneuvers are very important, it should not be too loose or tight. Strummer headset bearings come with standard ABEC-3 balls for optimum precision, durability, and smoothness. To protect the headset from water and dust, we use NBR (Nitrile Butadiene Rubber) seals on both sides.
