Your wheels are slowing you down! Steel bearings in your wheels work against you. By upgrading to F1 Ceramic wheel bearings, you are reducing resistance in your hubs. This is critical in high speed situations like races where pacelines are the norm and holding position is key.
Please note these kits are for Shimano MTB Hubsets rather than wheelsets.
Replace your slow steel balls with ceramic! This kit will replace both front and rear hubs.
Choose your front and rear hub.
