Cannondale F-Si Hi-Mod World Cup Review
Uniquely-forked, arse-kicking, ultralight XC racer but not for the faint-hearted or under-financed.
Cannondale F-Si Carbon 3 Review
It’s difficult to dispute the stealth, almost Darth Vader-like visage of the Cannondale F-Si… Power transfer is immediate, whether you’re seated or out of the saddle… The F-Si is a lively bike…
Cannondale F-Si Hi-Mod World Cup: Next Level [Spanish]
The F-Si remains an impetuous and somewhat nervous bike in the fastest descents . It’s very light and responds vehemently to any insinuation.
Review: Cannondale F-SI Carbon 5 [Dutch]
It is good to be able to report that this stripped down version gives the same quick impression as its much more expensive brother… the wheels are a lot heavier and the fork less stiff… but this is hardly a hindrance.
Cannondale F-Si Carbon 3
If you’re looking to get your first serious mountain bike, the Cannondale F-Si Carbon 3 should be vying for your attention. Road riders looking to get dirty, look no further… a serious competitive weapon.
