2020 Cannondale F-Si Carbon 4 Hardtail Mountain Bike in Grey

Season : 2020

Brand : Cannondale

Code : C25400M10

Weight : 0.01KG

A mountain race bike loaded with performance features that ensure victory, all while weighing next to nothing.

Key Benefits :

  • Designed For the W.
    At just 900 grams, F-Si is the lightest mountain bike frame we’ve ever made. Better still, our engineers built in real compliance, real durability, and the handling and features that really win races.
  • Next-Level Geometry
    F-Si attacks the steepest climbs and nastiest descents of modern World Cup XC courses. Ai offset drivetrain and OutFront steering geometry deliver an uncanny mix of stability, agility and traction.
  • The Best XC Fork…Period
    Simply the most advanced, smoothest, most precise-handling ultralight XC fork ever made. Its one-of-a-kind design lets it float through the chop and steer through the choss like nothing else.

Pre-Order

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!

Pre-Launch

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.
