Size Guide
Pre-Order

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

Your 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; ready for collection via Click & Collect or despatch 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 & Collection Dates

Estimated Delivery & Collection 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 & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

2020 Cannondale F-Si Carbon 5 Mens Hardtail Mountain Bike - Black

Season:2020

Brand:Cannondale

Code:C25500MBLK

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.

Full Tilt XC

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

Designed for the W

At just 900g, F-Si is the lightest mountain bike frame Cannondale have ever made. Better still, their 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

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 rocks like nothing else.

Get Connected

The Cannondale smart-phone APP, working seamlessly with the new Cannondale/Garmin integrated Wheel Sensor, automatically logs ride activity, has every detail about the bike and can even remind you when it's time for a tune up. The Wheel Sensor is fitted on selected 2020 bicycles and also available as a separate accessory.
