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

Trek Fuel MX 9 X0 AXS Gen 7 Mountain Bike in Lithium Grey/Trek Black Splatter

Season:2026

Brand:Trek

Code:58908GRY

The Fuel MX 9 X0 AXS is a playful trail bike made for hunting down side hits and chasing chaos.

Its Alpha NEXT Platinum aluminium frame is paired with a Fox Factory suspension package (150 mm rear, 160 mm front) and MX wheels for a ride that is flickable and zippy. It comes ready to rip with a wireless SRAM X0 Eagle AXS transmission that keeps shifts smooth under load and SRAM Maven Silver 4-piston brakes for massive stopping power.

Only you can define your perfect trail bike; that is why the 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 Fuel's new frame gives you loads of room for long dropper posts, bigger shocks, and frame bags. 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.

The SRAM Eagle T-Type transmission mounts directly to the frame, skipping the derailleur hanger. This makes for a more robust system that is cleaner-looking, more precise under load, and easier to set up.

Starting in 2024, Trek began removing high-emission aluminium from manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike made, including this one, had made the switch, driving a major drop in the footprint.

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 have loads of options for aftermarket upgrades, including angle adjust or anodised colours.
  • Active Braking Pivot: This allows engineers to tune how the suspension reacts to acceleration and braking forces independently, providing more confident control when you need it most.
