Wheel bearings are among the fastest rotating parts on a bicycle, so any additional drag has a material impact on drivetrain efficiency. Developed in partnership with a leading bearing manufacturer and following an extensive testing programme, Parcours ceramic bearings offer a new level of performance and durability for your wheels.
Parcours ceramic bearings are fitted with silicon nitride (Si3N4) balls which are substantially harder than their steel equivalents. This makes for a longer service life with lower wear rates, whilst also removing the risk of corrosion. All ceramic rolling elements are precision-machined with ultra-tight tolerances.
Each upgrade kit consists of:
2 front hub bearings
2 rear hub shell bearings
2 freehub bearings
Note: pricing includes fitting to wheel hubs
