Uniquely-forked, arse-kicking ultralight XC racer but not for the faint-hearted or under-financed. Buy if you want a fast and ferocious XC racer

Before the World Cup XC racing in Albstadt, we put in some first rides on Cannondale's next gen carbon XC hardtail & its all-new single crown Lefty fork. Built as an ultimate hardtail for steep & technically challenging modern courses, we turned some hot laps on the World Cup track, riding with the bike's design team.
