2019 Cannondale F-Si World Cup Carbon Hi-Mod Mens Mountain Bike Black

Season : 2019

Brand : Cannondale

Code : C25129MReplica

Weight : 15KG

The Cannondale F-Si has always been about pushing the limits of what an XC hardtail is capable of, and the new version pushes it harder and further than ever. No other hardtail descends as fast, climbs as nimbly, or kicks harder, smoother. With the otherworldly performance of the new Lefty Ocho, you've got a whole-new level of XC capability, tailor-made to feed the needs of the XC obsessed.

At just 900 grams, the all-new F-Si is the lightest mountain bike frame Cannondale have ever made. It shaves 80 grams off its predecessor, 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 engineers focused on features that deliver real performance benefits out on the course - features such as 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 all-new Lefty Ocho is the smoothest, stiffest ultra-light XC fork ever made. It floats through chop and steers through the choss like nothing else.

Short chainstays do wonders for traction and nimble handling, but they usually come at a cost. Not with Ai - this proprietary Asymmetric Integration drivetrain offset moves the gears and rear triangle over, helping creating space for much shorts stays while still having the clearance for big tyres and 2x drivetrains if you so desire. It even creates a stiffer, stronger rear wheel by evening out the dish.

Have you found the Cheaper?
Ask us to Price Match it now

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
