The Blackbearing D23 Headset Bearing is a replacement angular contact cartridge bearing designed for compatible bicycle headset assemblies. Its chrome steel construction provides a durable solution for replacing worn bearings and maintaining smooth, consistent steering.

Reliable operation: SAE52100 chrome steel races and balls provide durable rolling surfaces, while protective seals help prevent contamination. Quality grease supports consistent bearing movement during regular riding.

Compatibility: The D23 must match the original headset bearing's dimensions and contact angles. Bearings with different angular specifications or heights may not seat correctly, even when their inner and outer diameters match. Check the existing bearing markings before replacement.
