Specialized Rapide CLX II U Wheelset

Progettate per chi punta alla maglia a pois o alle grandi salite di montagna, le Roval Alpinist CLX III sono le ruote da strada più leggere mai realizzate da Specialized: appena 1.131 grammi, ovvero 134 grammi in meno rispetto al modello precedente.

Sviluppate in collaborazione con Arris, presentano raggi aerodinamici in materiale composito, più resistenti del 20% rispetto a quelli in acciaio, e consentono un risparmio di oltre 100 grammi per set ruota. Il risultato? Prestazioni in salita da record — come dimostrato da Demi, che ha migliorato il suo tempo sul Tourmalet di 5 secondi.
