ALPHA Wheel Bearings are built to turn every pedal stroke into speed, spinning freer under load while staying fast season after season. Pairing CeramicSpeed's proven low-friction bearing architecture with new hardened stainless-steel races and new custom light-contact seals for an even smoother, more durable wheel upgrade.

Hand-built in Denmark, every bearing uses super-smooth CeramicSpeed Class 1 silicon nitride ceramic balls, matched (within microns) to ultra-polished raceways and held by a reinforced polyamide cage for precise, stable performance.

ALPHA Wheel Bearings are optimised with low-viscosity CeramicSpeed All Round grease to minimise friction and assembled with our updated seals to reduce drag further and ensure dirt and moisture are kept out, so performance stays consistent in real-world conditions.

Tested to deliver up to 3 - 5x longer lifetime than standard bearings, ALPHA Wheel Bearings deliver rapid power transfer and keep top-end speed within reach for longer, across Road, Time Trial, Triathlon, Track, Cyclo-Cross and Mountain Biking in all conditions.
