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 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

Trek Fuel EX 8 XT Mountain Bike 2025 Nautical Navy

Season:2025

Brand:Trek

Code:25-41327-BLU

The Trek Fuel EX 8 XT Mountain Bike is an evolved trail bike, dialled for riders who chase down rowdy descents and want a bike that's happy to pedal back to the top and do it again. The lightweight alloy frame pairs with upgraded 12-speed Shimano XT drivetrain to keep shifting precise while a 150 mm FOX Rhythm fork with Float EVOL air spring cushions the blow from rocks and roots. In-frame storage and adjustable geometry give you all the perks that the come with the carbon model, but without the lofty price tag.

It's right for you if...

You want a full-suspension trail bike that floats over rough and technical terrain, and packs in plusses, like a root-slaying FOX Rhythm fork and Shimano's clean-shifting 12-speed XT drivetrain.

The tech you get

A light and stiff alloy frame with 150 mm FOX Rhythm fork with Float EVOL air spring and GRIP damper for small bump compliance, plus a FOX Performance Float X rear shock. A Shimano XT 12-speed drivetrain for snappy shifting and Tubeless-Ready Bontrager wheels. Plus, adjustable geometry that lets you take control of your set-up.

The final word

For the rider who doesn't want to be limited on the trail, the Fuel EX 8 is ready to handle everything. Its progressive trail geometry is built to keep you charging, and upgraded components are the cherry on top.

Trek Fuel EX 8 XT Mountain Bike Highlights

  • The Fuel EX Gen 6 gives you 140/150 mm of travel with extra adjustability features and more stable handling, plus a more robust frame with internal storage
  • You'll get upgraded components where it matters most, with 12-speed XT shifting and a rock-gobbling FOX Rhythm 36 fork
  • With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
  • The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  • We expanded our size range to ensure a better fit for all riders, and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels
