It’s that time when more and more 2019 models are hitting the market. This time, Cannondale is releasing an all-new F-Si hardtail and Ocho Lefty fork. Both are purpose-built for tackling today’s challenging XC race courses and both hit new marks in lightness and rigidity.

2019 Cannondale F-Si

The F-Si in World Cup guise is bonkers.

All-new F-Si

Let’s start with the F-Si. The new 2019 model again features Ai asymmetrically-offset drivetrain, which pushes the drivetrain 6mm outward. The result is shorter stays (427mm) for a nimble-handling bike and wider tire clearance. Additionally, wheel spoke tensions are identical left-to-right for a stronger rear wheel.

On top of that, the all-new frame drops 80 grams (900 grams total) to become Cannondale’s lightest mountain bike frame ever produced. Looking it over, the frame takes cues from the phenomenal Cannondale Synapse with an integrated seatpost binder, thin and compliant SAVE micro-suspension seat stays and a road-style 27.2mm seatpost diameter for a smoother ride.

Additionally, the new F-Si features OutFront geometry with a 69-degree head tube that can tackle gnarly terrain while still remaining nimble and responsive on the flats and climbs.

New F-Si Highlights:

  • Built to handle technical terrain of modern XC courses
  • Standard tapered head tube
  • Hidden seatpost collar
  • Speed release thru-axle
  • Durable BallisTec carbon
  • Flat mount disc brakes
  • Single-crown Lefty Ocho with OutFront (lighter, stiffer)
Cannondale Lefty Ocho Fork

The Ocho is a single-crown design that’s stiffer and lighter than previous designs.

With the new F-Si comes the all-new Lefty Ocho fork. With a single-crown design, the new Lefty Ocho looks simple and is way sexier than the dual crown design of yesterday. Dropping a whopping 250 grams from the previous design, the Ocho is one featherweight XC fork.

Lefty Ocho Highlights:

  • New single-crown design
  • As much as 250 grams lighter
  • Outfront offset for agile handling at slow speeds and stability at mach schnell
