Wheel bearings are among the fastest rotating parts on a bicycle, so any additional drag has a material impact on drivetrain efficiency.

Tripeak Ceramic Hybrid Bearings use Silicon Nitride balls, which will not rust or oxidize. Harder and more wear-resistant than steel, they 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: This Upgrade kit is suitable for Parcours Disc Brake Road Wheelsets for the model year 2022 onwards. This upgrade kit is not suitable for Parcours Gravel Wheelset (Alta).
