Roval Alpinist CLX III

The fastest way to get to the top
Roval Alpinist CLX III

Designed for those aiming for the polka dot jersey or epic climbs, the Roval Alpinist CLX III is our lightest road wheelset ever, weighing just 1,131g—134g less than the previous model. Developed in partnership with Arris, the new aerodynamic composite spokes are 20% stronger than steel spokes and save 103.5g per wheelset. Seeing is believing: Demi climbed the Tourmalet, beating her personal best by 5 seconds.
