The F-Si Carbon 2 is one of the most aesthetic bikes on the market. Above all, the rear triangle is a feast for sore eyes. We have checked all geometry measures and come to the following conclusion: the Cannondale Racebike is a very balanced customer. When sitting in the saddle, the posture is neither overly sporty, nor uber-comfortable. This should make the F-Si Carbon 2 suite the taste of most bikers. When the frame is Cannondale, its all about quality. The Carbon chassis is above average. Clever: At the push of a button on the handlebar, the complete suspension of the on sporty excursions can be blocked. For friends of sending it on rowdy trails: the last argument is still the strongest, because the harmonious geometry and the grippy tires cause you to smile from top to bottom in the descent. Cannondale gives 25 years warranty on the bike.
