Strummer precision bearings

Precision Cartridge Bearings (2RS)

Designed with the terrain your bike rides on in mind, our steel bearings are engineered to withstand high rotation and impact. They feature high-quality NBR (Nitrile Butadiene Rubber) seals on both sides to prevent dust and water from entering. A precision-made steel cage provides even spacing between the balls, allowing for smooth rotation during use. We use ABEC-3 steel ball bearings to achieve a good balance between precision, speed, and durability.

ACB Bearings for Bicycle Headset

The headset plays a crucial role in the functioning of a bicycle, contributing significantly to its functionality and performance. Steering maneuvers can have a significant impact on a competition. We understand that consistent, dependable, and smooth steering maneuvers are crucial; it should be neither too loose nor too tight. Strummer headset bearings feature ABEC-3 balls for optimal precision, durability, and smoothness. To protect the headset from water and dust, we use NBR (Nitrile Butadiene Rubber) seals on both sides.
