Cannondale F-Si Alloy 3 Mountain Bike 2016

  • Description


The F-Si Alloy shares much of the modern XC geometry, exceptional traction and explosive acceleration of its award-winning carbon brethren, but at a far more approachable price. It's World Cup DNA for the rest of us.


  • Race-inspired technology and features derived from their more expensive siblings.
  • Performance worthy of the name, even without the Carbon's Ai technology.
  • Incredible performance at inspiring prices.

RIDER PROFILE: For racers and discerning hardtail purists seeking exceptional XC performance value.

Key Features:

Every tube in the F-Si Alloy's frame has been tweaked and refined to reduce weight and deliver the best possible ride quality.

SMOOTH WELDS Trademark double-pass smooth welds showcase Cannondale's aluminium frame mastery. Since we don' t patch fill with putty and paint, our process eliminates the stress-risers and weak points found on traditionally welded frames, enabling us to build lighter, stronger frames everywhere in the line.

SHORT CHAINSTAYS Smart tube shaping and a curved seat-tube allows the chainstays to be quite short (436mm for 29/425mm for 27.5), which moves the rear wheel forward to be more under the rider, resulting in exceptional lateral stiffness and race-winning traction.

To achieve the best possible fit for all riders, size small is designed around 27.5 wheels, while M thru XL get 29"

Up front, the progressively slack 69.5° head angle gives the stability needed to attack on rough, fast descents, while the Lefty features increased fork offsets (55mm for 29 and 50mm for 27.5 ) to reduce "trail" and keep the steering quick and nimble in slower, tight, technical sections. In back, the super short chainstays make the bike extremely agile for technical manuverability and crazy traction.

Optimized seat stay and chain stay shaping provides vertical compliance for a more comfortable ride with no loss in lateral rigidity.

The oversized 1.5 Si headtube is ultra stiff and allows full compatibility with all steerer sizes - 1-1/8", Tapered, 1.5" and, for the ultimate upgrade, Lefty.
