Cannondale F-Si Carbon 4 (2021)

Cannondale F-Si Carbon 4 - A real Cannondale race bike with the new Lefty Ocho.

When it comes to sporty hardtails, Cannondale is at the forefront. The US company is one of the pioneers in the scene and has always built mountain bikes with their own unique character. Filigree and light frames made from the most modern materials. The new F-Si Carbon 4 is no exception. Quite the opposite, because this competition-ready hardtail is equipped with the unmistakable Lefty Ocho suspension fork. Thanks to needle bearing technology, the single-arm fork offers probably the best response of all CrossCountry lightweight suspension forks on the market. The riding position on the F-Si Carbon allows the rider to generate maximum propulsion. Thanks to the steeply sloping top tube, the compact geometry of the frame conveys a lot of safety on the trail. And in combination with the traction-strong 29-inch wheels, it creates ideal conditions for simply pushing away crisp ramps in a sprint. We offer the Cannondale F-Si in various equipment versions. Here as Carbon 4 with Sram NX Eagle 1x12 gears and Shimano MT500 disc brakes. The 160 mm discs save weight, but are only conditionally recommended for heavy riders.

Super light BallisTec carbon frame

With carbon bikes, one is tempted to look exclusively at the weight. Okay, at just under 1000 grams, the frame of the F-Si Carbon 4 really makes an impression. However, the real innovations are in the details: BallisTec carbon, which originates from the military sector, is characterised by exceptional durability and resistance. The SAVE Micro suspension developed by Cannondale ensures an amazingly comfortable ride on rough terrain. Vibrations are damped with the help of specifically placed flex zones on the rear triangle and thus do not reach the rider in the first place. It has been proven that the rider tires less quickly as a result. Another special feature is the Cannondale Asymmetric Integration System (AI): a drivetrain that is offset outwards by six millimetres creates more space behind the bottom bracket. For wider tyres, for example. In addition, the rear wheel gains stability thanks to a more even spoke angle. Many factors that together can give you some advantages in the race.
