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
Earn Rewards
When you purchase this item, you will earn of rewards points to spend on your next purchase from us. You can spend your Rewards balance in-store & online.

Hassle free returns

2021 Cannondale F-Si Carbon 5 Mountain Bike in Black

Season:2021

Brand:Cannondale

Code:C25601MCashmere

With a carbon frame that weighs in at just 900 grams, the Cannondale F-Si Carbon 5 Mountain Bike is super light and built for XC thanks to serious compliance, rugged durability and race-ready responsive handling that's aided by the Ai Offset drivetrain and OutFront steering geometry. The FOX Float Factory 32 SC fork lends 100mm of travel to smooth out rough terrain whilst maintaining precise steering and keeping weight low.

1x12-speed SRAM NX Eagle components keep shifting crisp, with the single front chainring simplifying maintenance and minimising any mid-ride complications. Let the burly 29" wheels carry rolling momentum over obstacles with ease and take speed off in an instant with the sure stopping power of Shimano MT500 hydraulic disc brakes, should a corner or descent have been taken a touch too enthusiastically.
Key Features:
  • Asymmetric Integration drivetrain for podium-level traction and clearance
  • Proprietary BallisTec carbon is custom-tuned for rigidity, compliance and weight-saving
  • Shimano MT500 hydraulic disc brakes
  • FOX Float 32 SC fork
  • Clean, configurable internal cable routing
  • SRAM NX Eagle 1x12-speed components

Click & Collect Orders

Please be aware Click & Collect orders may take some time to fulfil. We advise not to travel to your chosen store until you have been notified that your order is ready for collection.

Spread the cost of your new bike, helmet, safety equipment and accessories paying via instalments being taken directly from your wage. The payments for the Cycle To Work scheme are taken out of your gross wage and your Tax & NI contributions are then worked out based on your new lower gross wage which is how you save money on your new bike and equipment.

At the end of the time period specified with your Cycle To Work scheme you then have the option of buying your bike or to continuing to use it while you work for the company. If you decide to purchase the bike, the balance you owe will be based on a percentage of how much the bike was worth at the time you took out the Cycle To Work scheme.

We know how eager you'll be to jump on your new bike and hit the dirt or tarmac, so we give you everything you need to get you set up quickly. For full instructions on how you're bike will arrive and what you'll need to do, visit our How Our Bikes Are Built page
