Cannondale F-Si Carbon Black Inc. Ble
Breakout Integration. To create the fastest XC race rocket the world has ever seen, you've got to think a little differently. From its asymmetrically offset rear triangle and drivetrain to its new-school geometry and custom offset Lefty, every part of the new F-Si was designed as a System, fully Integrated in the pure pursuit of speed.
>A fully System Integrated approach to race-winning speed.
>Designed with the unique Ai offset rear triangle and drivetrain for categor y-leading efficiency, traction and clearance.
>The best handling 29'er hardtail in the world, thanks to the custom offset Lefty and System 29 geometry.
For XC racers and hardtail purists looking to gain time on their rivals in ever y section of the course.

Asymmetric integration (Ai) drivetrain
Our Ai design shifts the drivetrain and rear triangle to the right by 6mm. This creates an ultra stiff rear wheel by reducing dish, and delivers the shortest chainstays on the market, dual chainring compatibility, tons of mud clearance, and a super responsive rear end.
Stiffer rear wheel
By keeping the rim and tire in line with the centerline of the bike, but shifting the hub and cogs 6mm to the right, we make the spoke angles more even on both sides, creating a stronger wheel that's up to 60% stiffer than a conventionally laced wheel, while using a standard rim and normal 135mm hub.
The Ai system allows for the shortest chainstays on the market (429mm), which moves the rear wheel forward to be more under the rider, resulting in exceptional lateral stifness and racewinning traction.
Ai hollowgram spider
The F-Si spider moves the chainrings out 6mm to match the rear triangle with no change in Q-factor. This enables the super short chainstays while providing ample mud clearance for the tire and maintaining double and single ring compatibility.
System 29 geometry
Up front, the progressively slack 69.5° head angle gives the stability needed to attack on rough, fast descents, while the Lefty’s proprietary 29'er-specific 55mm fork offset reduces “trail” keeping 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.
Speed Save micro-suspension
By pairing precise tube shapes with sophisticated carbon lay up, we are able to create areas on the rear chainstays and seat stays and seatpost that can deflect to absorb shock, while staying completely rigid laterally and torsionally. This enhanced vertical compliance greatly improves rider comfort and rear wheel traction, so you can ride faster, longer.
SAVE 2 seatpost
The all-new SAVE seatpost has been redesigned to save almost 50 grams and deliver 20% more deflection. It has a more linear deflection curve, which means more comfort, especially for lighter riders, while maintaining strength for max loads.
Our proprietary carbon construction method pairs ultra strong military armoring fibers with high strength resins and a tightly controlled network of high-modulus stiffening fibers to deliver ultra light frames with exceptional strength and ride-feel. Oh yeah, and lifetime warranties.
