All-New Cannondale F-Si Carbon

The incomprehensible amount of innovation and engineering in the all-new Cannondale F-Si boils down to one simple fact: This is the fastest XC race hardtail ever made. Fastest on the climbs, Fastest on the descents. Faster everywhere. Designed to match the commitment of the XC obsessed rider, from the grass roots to the World Cup.

For many, the XC hardtail remains the purest expression of mountain bike technology. And the F-Si Carbon is the purest of the pure.  Featuring a modern Cross Country geometry – low, flat back with centred weight distribution.

CATEGORY: CROSS COUNTRY RACE.

At just 900 grams (size Med, with all paint and hardware), the all-new F-Si is the lightest mountain bike frame Cannondale has ever made. It shaves 80 grams off the previous F-Si, and when you factor in the svelte new Lefty Ocho, you save a whopping 330 grams on the frame and fork.

What’s even more impressive is that, rather than chasing marketing grams, Cannondale’s engineers focused on features that deliver real performance benefits out on the course. Features like Ai and OutFront, or improved compliance, or improved durability. That’s what wins races, not saving the weight of a few sips of water!

The F-Si’s frame is made from Cannondale’s proprietary BallisTec carbon, a sophisticated layup of military-grade fibres and high-impact resins that offers unparalleled levels of stiffness, smoothness, lightness and ultimate robustness.

Featuring a slacker head angle than the previous F-Si adds even more stability and control on sketchy descents. Custom 55mm long fork rake on the Lefty Ocho keeps handling precise and agile at slower speeds.  The Ai offset drivetrain delivers even shorter chainstays than the original, for climb-winning traction and agility, with clearance for big tyres, 2x and 1x chainring compatibility, and a stiffer, stronger rear wheel.

Reach to the head tube is increased slightly for improved control.  An integrated seat binder looks super clean and exposes more seatpost length for improved comfort. While new race-tuned stiffness keeps things super rigid where needed for power transfer, but adds even more bump-eating comfort so you can go harder for longer.

ALL-NEW LEFTY OCHO FORK

The first single-crown, single-sided XC suspension fork in the world saves weight in the most obvious way.  With just one crown and one leg, all material is concentrated where needed for strength and stiffness, making it one of the lightest suspension forks in the world — 250 grams lighter than previous Lefty. Less un-sprung mass than traditional forks for better suspension response. And a tapered steerer for lighter weight and total compatibility.

Suspension is movement. The smoother it can move, the better it can do its job. Insulating you from impacts. Floating through the chop. Tracking over the things that would throw you off. When it comes to smoothness, Ocho stands alone. Fewer friction-causing bushings and seals than any other fork. The supple new Chamber damper. And the new Delta Cage evolution of Lefty’s revolutionary needle bearing telescope assembly. It all adds up to the smoothest fork ever made. No sticking, no binding, no shuddering or hesitation, no matter how hard you push it.

Lefty Ocho has the best overall stiffness of any lightweight XC fork, which is great. But what separates it from the rest is not so much how stiff it is, but rather how it is stiff. Because stiffness, like so many things, is a double-edged sword: Too flexy and you’ve got a noodle that won’t go where it’s told. Too stiff, or stiff in the wrong places, and it wants to ricochet and bounce, instead of float and flow. Ocho’s unique single-crown design, and triangle-in-triangle telescope, give Cannondale unprecedented ability to tailor the stiffness of the fork.

Ai – ASYMMETRIC INTEGRATION

Short chainstays do wonders for traction and nimble handling, but they usually come at a cost. That’s not the case with Cannondale’s proprietary Asymmetric Integration drive-train offset.

By moving the gears and rear triangle over, Cannondale are able to create space that enables them to shorten the stays AND still have clearance for big tires and room for 2x drivetrains if you want.

It even creates a stiffer, stronger rear wheel by evening out the dish.

SPEED RELEASE

A faster kind of thru-axle. Slotted dropout design lets the axle stay in the hub for quicker, easier wheel changes.

Compatible with standard 148×12 hubs, it’s just a better way thru.

Other frame improvements in the new F-Si include:

  • Tapered Headtube – the new F-Si uses a tapered headtube, for better compatibility and lighter weight.
  • Interchangeable Routing Chips – easy-to-use internal cable routing chips allow you to customize your cable routing to your preference.
  • Integrated Seat Binder – a wedge-style seat binder in the seat tube eliminates the collar for a cleaner look and allows more seatpost flex for more comfort.
