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.

This Trek Fuel EX 8 in Small is an ex-display bike having been on display in our showroom but otherwise the bike is as new.

Our ex display bikes are fully serviced and checked to ensure your riding experience is the same as a new bike - we offer full manufacturers warranty on all our ex display and ex demo bikes.

The Fuel EX 8 XT 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 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.
