"Big light wheels - check. Clean lines and classic double diamond design - check. Lefty - check. Cannondale's timeless XC frame appeal definitely catches the eye - and this for under £1,700!" - Factory Jackson
An XC weapon with a World Cup pedigree, the F-Si combines modern XC geometry with Cannondale's renowned SmartFormed Alloy frame construction to deliver killer race performance at a more approachable price. Aspiring XC racers looking for a bike to take their performance to the next level.
SMARTFORMED ALLOY
Cannondale aluminium construction is focused on delivering the strongest, lightest, best handling frame possible. Premium 6069 and 6061 alloy tube sets are highly manipulated to extract every ounce of performance. Double-pass welds provide stronger, smoother joints and eliminate the need for internal reinforcements or external welded-on gussets. Each frame is heat treated after welding to maximise the strength and hardness of the aluminium, increasing long-term durability. These and other processes allow Cannondale to continue to offer a lifetime warranty on each of its alloy frames and forks.
SAVE TECHNOLOGY Go Smoother. Go Faster.
Cannondale SAVE micro-suspension technologies are the industry’s premier vibration and shock reduction systems. SAVE uses engineered flex in the frame and fork to not just reduce felt vibrations, but also increase the consistency of tyre contact on uneven surfaces. As a result, SAVE-equipped Cannondale frames roll faster through bumps with confident, neutral handling in any conditions.
