Aluminium full-suspension mountain bike Trek Fuel EX 9 X0 AXS Juniper green: wireless T-Type, 150/145 mm

Trek Fuel EX 9 X0 AXS Juniper: mechanical or electronic, the real choice

The Trek Fuel EX 9 X0 AXS Gen 7 shares its Alpha NEXT Platinum aluminium frame and RockShox Ultimate suspension (150 mm front, 145 mm rear) with the Fuel EX 9 Eagle 90, but replaces the mechanical drivetrain with a wireless SRAM X0 Eagle AXS T-Type and the brakes with Maven Silver. Trek has not published a weight for this version; the closest reference is 16.88 kg in size M for the Fuel EX 9 XT Di2, with the identical frame. Matte Juniper/Blue Sage Splatter is a matt juniper green flecked with sage blue.

Technical specifications

Who is it for?

For the mountain biker torn between a mechanical and an electronic drivetrain who wants to understand what AXS really brings. It will appeal to riders who ride often and want to spare themselves cable adjustments.

The LVR workshop view

Alpha aluminium, Trek's expertise. The Fuel EX 9 X0 AXS is the only aluminium Fuel to get a SRAM electronic drivetrain, and with no derailleur cable, its frame houses only the rear brake hose and the dropper post cable, both routed internally. Alpha NEXT Platinum is the highest tier of Trek's alloys, ahead of Alpha Platinum (Procaliber, Slash 8) and Alpha Silver (Marlin). The frame kit weighs 4.95 kg in M and keeps the adjustable progression of the Gen 7.

In short: here you get a carbon-level drivetrain on an aluminium frame. It is a coherent choice if the precision and robustness of wireless matter more to you than the 1.64 kg the OCLV Mountain frame kit would save.

The difference from the mechanical Eagle 90 lies not in the sprockets but in the shifting: the X0 AXS changes gear with the same precision whatever the dust, mud or housing wear. The X0 derailleur is also more refined, with more replaceable parts in the event of a knock.

The Maven Silver brakes sit one step above the Bronze in the SRAM range, with the same 4-piston power. We bleed them when we hand the bike over and show you how to adjust the reach to the size of your hands.

Which Fuel should you choose?

Our take: with identical suspension, this X0 AXS differs from the Fuel EX 9 Eagle 90 in its wireless drivetrain and Maven Silver brakes. The Fuel EX 9 XT Di2 makes the same choice on the Shimano side, with Fox Factory suspension.
