A new generation of Lefty is here

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.

The top metal F-Si is an impressively fast yet controlled and fatigue-free flyer. Buy if you favour alloy over carbon and enjoy racing rough, rocky trails on a forgiving ride
Impressively smooth and speed-sustaining yet efficiently quick frame, the Lefty fork is stiff, accurate and well damped
OK but not outstanding component selection, even with alloy frame
Specific front wheel and metal, QR axle frame limit upgrade potential
