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. Equipped with high-quality NBR (Nitrile Butadiene Rubber) seals on both sides to prevent dust and water from entering. The precision steel cage provides even spacing between balls, allowing 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 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.
