Roval Alpinist CLX III front wheel

The fastest way to the top

Designed for those aiming for the polka dot jersey or epic climbs, the Roval Alpinist CLX III are our lightest road wheels ever, weighing just 1,131 g, 134 g less than the previous model. Developed in collaboration with Arris, the new aerodynamic composite spokes are 20% stronger than steel and save 103.5 grams per wheel set. Try them for yourself.

A new frontier in lightness
Arris' Roval Aero composite spokes are 134 g lighter, resulting in a wheel set that weighs only 1,131 g.

Demi's 5 seconds off
With the Alpinist CLX III, Demi beat her Tourmalet record by 5 seconds.

Tested. Unmatched. Alpinist.
The hooked rims withstand up to 110 PSI, twice the average standard impact, while remaining ultra-lightweight.
