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

2019 Cannondale F-Si Hi-Mod Limited Edition Mens Mountain Bike - BBQ

Season:2019

Brand:Cannondale

Code:C25139MMATBLK

If you're obsessed with XC, the all-new F-Si is the bike for you. Built to climb faster, descend harder, and sprint better than any other hardtail out there, it's serious XC goodness for those with serious XC issues.

  • ALL-NEW Lefty Ocho Carbon, 29", 100mm, Chamber Damper with cable lockout, OppO Spring System, tapered steerer, 55mm offset
  • HollowGram 23 Superlight rims with HollowGram 148x12 rear w/DT internals rear hub
  • Shimano XTR Drivetrain, 12-speed / Shimano XTR Race Hydro Disc Brakes / Cannondale HollowGram Si Crankset

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 and 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.

Lighten Up

Light weight not a lightweight

Lefty Ocho OutFront

The all-new Lefty Ocho is the smoothest, stiffest, ultra-light XC fork ever made. It floats through chop and steers like nothing else.

Ai Party in the Back

Short chainstays do wonders for traction and nimble handling but they usually come at a cost. Usually you've got to give something to get something but not with Ai.

BallisTec Carbon

  • SAVE Micro-Suspension
  • Hidden Seatpost Collar
  • Speed Release Thru-Axle

Cannondale's proprietary Ballistec Carbon lets you push the boundaries and tune rigidity throughout the entire frame for stiffness where you need it and compliance where you don't. At just 900g (size M with all paint and hardware), it's one of the lightest hardtails in the world, yet so durable it is backed up with a lifetime warranty.

  • Industry Standard Tapered Headtube - Light, stiff, standard
  • Interchangeable Routing Chips - Clean, configurable internal cable routing
  • Flat Mount Brakes - Latest meets greatest
