Press Release:


When the Cannondale Factory Racing Team saddles up for one of the toughest courses on the XC World Cup circuit in Albstadt, Germany this weekend they’ll have two new aces up their sleeves: the all-new F-Si, the fastest and most capable hardtail Cannondale has ever made; and the Lefty Ocho, the smoothest, most advanced ultralight XC fork in the world.

 

All-New F-Si


Introduced in 2015, the original F-Si was a game changer for XC hardtails. It was the first hardtail designed to really handle the challenging new courses of the World Cup.

For the new F-Si, Cannondale has taken everything that made the original great, like OutFront geometry and the agile Ai rear triangle, and pushed it harder and further than ever. The new F- Si is lighter, smoother, more capable and flat-out faster than any other XC race hardtail out there. It’s the ultimate race machine for the ultimate cross-country fanatic.

 

Faster on the climbs. At just 900 grams, the F-Si Hi-MOD frame is 80 grams lighter than its predecessor and is the lightest mountain bike frame Cannondale has ever made. Even better, its updated Ai offset drivetrain delivers super-short 427mm chainstays for more
climb-winning traction and agility, and clearance for full 2.35” tires.

 

Faster on the flats. New race-tuned stiffness retains sprint-winning rigidity, but adds significant compliance throughout the frame for reduced fatigue and better control.

Faster on the descents. An even slacker 69° head angle, combined with Lefty’s special extra- long fork offset, creates a version of Cannondale’s OutFront geometry with even more descent-shredding abilities, while maintaining the nimble quickness needed for top-level XC racing. And of course, leading the way is the unrivalled performance of the new Lefty Ocho.

 

Packed with so much cross-country goodness, the all-new F-Si is tailor made to feed the needs of the XC obsessed.

 

 

The Lefty Ocho


It’s been more than 18 years since the first Lefty suspension fork showed the world what kind of performance was possible if you stopped worrying about what was impossible, and the new Lefty Ocho is poised to do it all over again. The disruptive seventh son of the original XC disruptor, it is not only the world’s first single-crown, single-sided suspension fork; it is the most advanced, smoothest, most precise-handling ultralight XC fork ever made.

The all-new Lefty Ocho is for the XC rider who believes in results. The incredibly smooth suspension action that results from the lowest friction of any fork structure out there. The climb-crushing speed that results from having one of the lightest suspension forks in the world. The line- owning precision that results from having best-in-class overall stiffness, tuned for maximum control. And the confidence that results from knowing you’re on the most advanced, ground-breaking, preconceived-notion-destroying, XC- race-winning fork ever created. They’re the kind of results that result in...well... real results.

 

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. One crown makes a king.

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. Delivering you where you want to go. 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. Just pure, smooth action always, for ultimate control.

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 us unprecedented ability to tailor the stiffness of the fork. For the stiffness to go, and the give to flow.

A deeper look at the details.

  • The world’s first single crown, single-sided suspension fork, for singularly impressive performance.
  • Normal tapered 1-1/2” to 1-1/8” steerer. Lighter. Simpler. Standard.
  • Simple, reliable cable remote lever engages lockout on the fork or fork and rear shock.
  • Guide Guard. Simple and Strong. Guiding the brake cable smoothly and quietly in any situation.
  • With just one leg, Ocho has way fewer seals, for way less friction, for way smoother action.
  • SideCar Air Valve. Easier to access. Reduces rotor contamination.
  • Rebound Adjust.

Lefty Ocho Features:


Cable Lockout
Simple, reliable cable remote lever engages lockout on the fork or fork and rear shock.

 

Chamber Damper
All-new self-bleeding, heat compensating, high flow damper, with external compression and rebound adjust. Smooth, supple, spike-free damping in all conditions.

 

Triangle- in-Triangle
Ocho’s three-sided needle-bearing interface keeps the inner leg from rotating within the outer leg, for uncanny steering precision.

 

Delta Cage Needle Bearings
Don’t bind. Roll smoother than ever with the new Delta Cage version of Cannondale’s legendary needle-bearing telescope assembly.

 

Stop Lock Brake Mount
Self-aligning brake mount removes with just one turn of a 5mm hex and the press of a button. Quicker, simpler wheel removal.

 

Single Crown Structure
The world’s first single crown, single-sided suspension fork, for singularly impressive performance.

Its hot...but I'd struggle to get my head around a single crown Lefty. It just looks scary...

Hell that's nice !!!

 

Suddenly my 2008 Lefty is starting to look a little dated !!

Whenever I see a Cannodale with a Lefty fork, I'm always disappointed they did not balance the bike by making a right side (drive side) only seat and chain stay for the rear wheel.

I, for one, would like to see a little more innovation from Cannondale!

What should  balance the right hand drive train out then? ^_^

So it's now only ~200g heavier than a Fox 32 SC or RS Sid. At least you can take sharp left turning switch backs now.

But Sauser says that under acceleration the bike is unbalanced because there is no right leg. :-)

This is what Cannondale is all about. I respect their approach to things and hope I can test and possibly buy this bike and fork combo in the future.

Mongoose!, May 18 2018 12:43

Black Inc model in this... :thumbup:

Meh

Now if they can only put a Bain in there - Winner

Rocket-Boy, May 18 2018 06:35

So it looks like they have addressed the complaint I have heard most from lefty owners about difficulty in removing the front wheel.

Other interesting thing is that its now just a normal tapered steerer tube, so does that mean they are going to be looking at selling forks only for other bikes if the compatibility is there?

Grease_Monkey, May 18 2018 09:37

I always poke fun at lefties, but dam - this is HOT!!! If I were a 60kg, skinny, XC junky this would be a wet dream.

Koei, May 18 2018 11:03

Wow.

 

Is this what forbidden love feels like?

 

Also great to see another international brand using Stellies as an ad backdrop. 

Today's Plan, May 19 2018 05:09

The R&D and testing by the Proffies in the field will set this fork out alone, think this is a game changer for a bike brand to be pushing limits like this on something that they could just go shopping for off the shelf - nice to see!

Well it sure worked for him , he won a couple of WC tiles on it

mada3400, May 20 2018 01:26

That may be the best looking xc hardtail ive ever seen with that fork

LOSMEICHERIE, May 21 2018 07:18

Is that a nomarl side tapperd steerer tube?
