Aluminium full-suspension mountain bike Trek Fuel EX 9 X0 AXS Sedona red: X0 AXS 10-52, Maven, 150/145 mm

Trek Fuel EX 9 X0 AXS Sedona Red: electronics for long days

For rides of several hours, the Trek Fuel EX 9 X0 AXS Gen 7 offers a wireless SRAM X0 Eagle AXS drivetrain with 10-52 cassette, Maven Silver brakes and RockShox Ultimate suspension with 150 mm at the front and 145 mm at the rear, on an Alpha NEXT Platinum aluminium frame. Trek has not published a weight for this version; as a reference, the Fuel EX 9 XT Di2, with the identical aluminium frame, comes in at 16.88 kg in size M. The Matte Sedona Red/Pennyflake Splatter colour is a matt terracotta red flecked with copper flakes.

Technical specifications

Who is it for?

For the mountain biker who strings together big loops, raids and days of 50 km or more, and wants to keep precise shifting from the first kilometre to the last, even when fatigue makes their movements less precise.

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.

At the end of the day, hands get tired: the AXS shifter takes minimal effort and never misses a gear. On a long track climb in the Espinouse, you run through the sprockets smoothly, and the derailleur does not move a millimetre when the chain vibrates on descents.

The Maven Silver brakes, with a 200 mm rotor at the front, keep their power consistent on the descents that follow hours of pedalling. We recommend heading out with a charged AXS battery before every big ride: it comes off and is recharged in a few moves.

Which Fuel should you choose?

Our take: the X0 AXS uses the suspension of the Fuel EX 9 Eagle 90 and moves to wireless. On the Shimano side, the Fuel EX 9 XT Di2 also offers electronics, with Fox Factory suspension, for 16.88 kg in M.
