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.

Trek Fuel MX 9.9 X0 AXS Gen 7 Mountain Bike in Purple Phaze/Amethyst Marble

Season:2026

Brand:Trek

Code:55916PUR

The Fuel MX 9.9 X0 AXS is Trek's top-tier carbon trail bike, built for chasing the wilder things in life.

This bike 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. SRAM's wireless X0 AXS transmission delivers crystal-clear shifting, even under load, while 4-piston SRAM Maven Silver brakes give you the modulation and power you need. It is topped off with a Fox Transfer NEO dropper post and carbon Bontrager Line Pro 30 wheels.

The Fuel's new frame gives you loads of room for long dropper posts, bigger shocks, and frame bags. Active Braking Pivot allows engineers to tune how the suspension reacts to acceleration and braking forces independently, meaning you get more confident control when you need it most.

Features:

  • Adapt, rip, repeat: The Fuel is available in three adjustability-packed configurations (EX, MX, LX).
  • 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.
  • Storage and accessory mounts: Stash ride essentials with in-frame storage on all Fuel models (carbon and alloy). Top tube accessory mounts let you load up even more.
