Product Details
The fastest XC race rocket the world has ever seen! 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. The new F-Si is the most integrated, most advanced and fastest XC race bike ever made and these bikes are lighter, stiffer, better handling and simply faster than anything else out there. Shimano XTR/XT shifting components underline the standard of this bike, provide high transmission bandwidth and guarantee highest precision and durability. The extremely stiff Cannondale Hollowgram Si crankset in connection with the PF3 bottom bracket does not waste a single watt. Hydraulic Magura MT-RACE disc brakes enable a powerful and save brake performance in all conditions. A very lightweight Cannondale CZero carbon wheelset forgives even tough line choices and can be prepared for tubeless setup. The Cannondale F-Si Save Carbon seatpost gives extra comfort. Well thought technologies, great components and one of the lightest and stiffest forks available unified in one 29'er race hardtail. The lightweight frameset is a mark all other competitors have to beat. Fantastic stiffness to weight values underline the know how of Cannondale and let it be a perfect choice for hardest competitions. Cannondale reached that target by implementing several innovative technologies and materials in their concept. F29 Carbon achieves unheard of levels of light weight and efficiency by System Integration design. Cannondale designs components to work together, like the new Lefty Hybrid fork and the Stem/Steerer, or the crankset with the PF3 system. Lighter and stiffer than aluminum, more shockproof than steel. Ballistec carbon can shake off rock strikes and impacts that would destroy F-Si's flimsy competition. Tube2Tube Construction is a time intensive and expensive construction procedure which is used by Cannondale to create every tube individually and to arange the unidirectional fibers exactly. This results in increased stiffness and further reduced weight. The Speed Save System with its optimized chain- and seat stay shaping offers lateral rigidity, while providing vertical compliance for bump absorption and comfort with no loss in power transfer. Ai Drivetrain Asymmetric Integration - The heart of the F-Si's System Integration is the all-new, Ai, asymmetrically offset rear triangle and drivetrain. The offset shifts the rear hub and drivetrain 6 mm to the right, delivering super short chainstays without any of the usual compromises, and a rear wheel that is dramatically stiffer and stronger because the spoke tension and angles are equal on both sides. Cannondale then integrate this with their new Ai HollowGram spider, which moves the chainrings an equal 6 mm to the right, balancing the system and maintaining perfect chain-line, shifting performance and Q-factor. This elegantly simple approach - Ai - enables them to have their cake and eat it too. The extra space created by shifting the drivetrain outboard enables the F-Si to have: - The shortest chainstays on the market, for incredible traction, stiffness and agility. - Up to 6% increase in rear wheel stiffness. - Dual chainring compatibility with super short stays. - Tons of mud clearance. - Ample tire clearance with the chain and front derailleur. System 29 Geometry When it comes to the way a bike handles, geometry is everything. The difference of just a few millimeters here or a half a degree there can significantly impact handling. Cannondale developed a winning 29er geometry for the F29 but World Cup competition is changing. With courses becoming ever more technical, steep and brutal, they knew that they have to rethink XC geometry completely. The result is F-Si - a bike that defines new-school XC handling and speed. Super Short Chainstays: Category leading, super short (429 mm) chain stays, which were extremely agile in tight and technical terrain, especially when navigating switchbacks. That also puts more of the rider weight over the rear wheel, dramatically increasing rear wheel traction on steep climbs. Slack Head Angle with 55 mm Offset Lefty: Progressively slack 69.5° head angle mated to the Lefty's proprietary 55 mm fork offset, the nimble rear end is complemented by equally agile and capable steering. At high speeds, the added stability of the slack head angle enables the rider to attack rough terrain with confidence. In slower, tight, technical sections, the extra fork offset and resulting lack of "trail keep the steering quick and nimble. Lefty 2. A bike as radically new and boundary-pushing as the F-Si demands an equally radical fork to complement its freakish handling and stiffness. For the uninitiated, Lefty has always been the lightest, stiffest, smoothest, and most durable front suspension on the start line: XC+ Damper Who says an XC rocket can't borrow technology from the enduro world? The new Lefty gets the same new smooth and supple damper technology found in the new SuperMax forks, but tuned for XC. Dual Integrated Crowns Stiffer and stronger than single crown setups. The Lefty 2. has multiple clamp widths, lowering the front end heights of Cannondales small, medium and large sizes. Inverted Design Inverted design is not just stiffer and stronger, it's also better lubricated. Gravity holds lube against the seals and bearings for longer life and smoother action. Oversized Clamp Area The Lefty gets an updated structure which grows to 44 mm in diameter at the clamp areas. This keeps the fork svelte, but adds even more stiffness and strength. Hybrid Needle Bearing System For maximum control, SuperMax's proprietary needle bearing assembly keeps the suspension smooth, no matter how hard you brake, corner, or land. New 29 Specific Offset To complement the F-Si's ninja-like rear end handling, the new Lefty uses a 55 mm offset, which is longer than the competition. When combined with slack head angles, this creates the perfect balance of high speed stability and low speed agility. For 217 it comes with a new air spring assembly, called 2Spring. This internal update decreases the strut's activation force by 7 lbs and makes for longer service intervals. Overall it offers 1 mm air suspension, a hydraulic remote lockout and adjustable rebound damping.
