Fast, composed and damn-good looking, Cannondale's F-Si Carbon 3 proves the hardtail concept is anything but dead
Stealthy aesthetics
Impressive ride quality
Telepathic handling dynamics
Decent spec level
Could be lighter

A sleek, race-ready cross-country weapon

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
Unique fork and wishlist kit spec make it a real head turner, seriously light yet stiff enough to track hard, well-controlled but lightweight fork, nicely balanced between max power delivery and reasonable punishment
Unique features can create spares issues, high cost goes with the territory, not the lightest frame, fork or off-the-peg bike

This carbon hardtail is light, sharp, and features the distinctive Lefty Ocho fork
May 2018
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.
