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