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.

Trek Fuel MX 9.8 Eagle 90 Gen 7 Mountain Bike in Gloss Dark Carmine/Matte Trek Black

Season:2026

Brand:Trek

Code:56306RED

The Fuel MX 9.8 Eagle 90 is a chaos-craving carbon trail bike built for hitting bonus features.

It starts off with an OCLV Mountain Carbon frame, specified with a Fox Factory suspension package (150 mm rear, 160 mm front) and MX wheels for getting wild on the trail. A mechanical SRAM Eagle 90 transmission gives you reliable shifts without the fuss of electronics, and 4-piston SRAM Maven Bronze brakes deliver power you can count on.

Only you can define your perfect trail bike – that's why Fuel is available in three adjustability-packed configurations. Get do-it-all capability with EX, go pop-happy with MX, or charge through it all with LX.

The SRAM Eagle T-Type transmission mounts directly to the frame, skipping the pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner-looking, it's also more precise under load and easier to set up.

The Fuel's new frame gives you loads of room for long dropper posts, bigger shocks, frame bags, and more.

Stash ride essentials with in-frame storage on all Fuel models – both carbon and alloy. Plus, top tube accessory mounts let you load up even more.

Features:

  • Adjustable leverage rate: Flip the chip in the lower shock mount for a more progressive leverage rate, offering more bottom-out resistance without giving up small-bump sensitivity.
  • Zero stack integrated headset: With a ZS standard headset, you've got loads of options for aftermarket upgrades, including angle adjust.
  • Active Braking Pivot: Allows Trek's engineers to tune how the suspension reacts to acceleration and braking forces independently, meaning you get more confident control when you need it most.
