A Gravaa KAPS (kinetic air pressure system) hubset system has been spotted on Team Jubmo-Visma rider Edoardo Affini's Cervelo S5 at Dwars door Vlaanderen today.
Pictures of the bike shared on Twitter before the race show the Cervelo S5 fitted with Reserve carbon wheel rims (as usually used by the team) laced onto Gravaa KAPS front and rear hubs. These hubs feature an adjustable tyre pressure system using Bluetooth and Ant+ controls to allow the rider to adjust and control tyre pressures via a handlebar-mounted control unit.
