Cannondale F-Si Hi-Mod World Cup review

Jan 2019 · Guy Kesteven

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

Highs
  • 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

Lows
  • Unique features can create spares issues, high cost goes with the territory, not the lightest frame, fork or off-the-peg bike

First Rides: Cannondale F-Si hardtail & Lefty Ocho fork on a World Cup XC course

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.
