MR136 Bicycle Headset Bearings

The MR136 Bicycle Headset Bearings are high-precision sealed bearing assemblies primarily used in bicycle steering systems.

This model utilizes high-quality bearing steel and features a highly efficient sealing structure that effectively prevents dust, moisture, and impurities from entering the bearing.

The precise fit between the balls and raceways reduces friction, resulting in smoother and more stable steering.

Applications: Mountain bikes, road bikes, e-bikes, and urban commuter bikes.
