Kogel 6903 Cross Ceramic Wheel Bearing

The Kogel 6903 Cross Ceramic Wheel Bearing (17x30x7mm) is engineered for riders who demand superior performance and resilience in challenging conditions. With cross seals designed for optimal protection, these bearings are ideal for mountain biking, cyclocross, gravel adventures and wet-weather road riding.

Silicon Nitride Advantage: At the core of Kogel’s performance is the use of silicon nitride ceramic balls. These balls are exceptionally smooth, harder than steel and resist compression under load. This results in minimized friction, enhanced durability and consistent performance in both dry and adverse conditions.

Seamless Speed and Efficiency: Kogel ceramic bearings are built to reduce rolling resistance and deliver a smoother, more responsive ride. With each pedal stroke, riders benefit from faster acceleration, better momentum retention and greater control—transforming every ride into a high-efficiency experience.

Built for the Long Haul: Cross seals provide maximum defense against dirt, moisture and debris, making these bearings suitable for riders tackling unpredictable terrain or poor weather. With increased durability and protection, you’ll spend less time on maintenance and more time riding.

Whether you’re a competitive racer or a weekend explorer, switching to Kogel’s ceramic wheel bearings brings an immediate performance boost. Expect quieter operation, longer service life and a smoother feel on every ride—an investment that pays off in every kilometer.
