Cannondale F-Si Bikes For Sale

Bikes are meant
to be used.

Cannondale looks to itself when designing the future. The F-Si is a perfect example of this. When Cannondale updated the Flash/F29 to the F-Si, the bike became lighter and more agile thanks to a few tweaks. They shortened the chainstays that can still fit 2.35” 29er tires thanks to Ai (Asymmetric integration). Cannondale also increased the fork's offset, increasing stability at high speed. They were able to shorten the headtube to allow people who like getting low to get lower. And the thing is light; the Hi-MOD version is a svelte 900g.

Cannondale keeps names and models simple. While there are Ultimate, World Cup, Team, 1-5, and women-specific versions. There are basically three frames. A standard carbon, a Smartformed aluminum, and more recently, a Hi-MOD carbon. Most bikes come with a Lefty fork, while the entry-level models typically come with a traditional fork.
