Cannondale has been one of the leaders in 29er hardtails for years and that looks to continue for 2015 and beyond. The all-new 2015 Cannondale F-Si aims to deliver playful handling and capable descending all while remaining a true XC race hardtail. The technical nature of today’s World Cup XC race courses demand the best of all worlds and having a more flickable and fun bike will give more capable riders a greater edge.

To achieve this, Cannondale engineers have re-designed the entire platform — including modifying the Lefty’s fork offset and tweaking the rear hub spacing to allow the wheel to tuck in closer to the bottom bracket for an ultra-short 16.88″ chainstay. They also stuck with a quick-release rear axle, stating their changes have made it stiffer and more serviceable than a 142×12 thru-axle.
