Aluminium full-suspension mountain bike Trek Fuel LX 9 Eagle 90 matte red: ZEB Ultimate, Maven, 17.38 kg

Trek Fuel LX 9 Eagle 90 Sedona Red: long days of enduro

Designed for full days in the mountains, the Trek Fuel LX 9 Eagle 90 Gen 7 pairs a 170 mm RockShox ZEB Ultimate fork, a 160 mm Vivid Ultimate shock and an Alpha NEXT Platinum aluminium frame, for 17.38 kg in a size M. The SRAM Eagle 90 drivetrain has a 10-52 cassette so you can climb back up without pushing. Its Matte Sedona Red/Pennyflake Splatter finish mixes a matte brick red with copper-coloured flakes.

Technical specifications

Who is it for?

The right choice for the mountain biker who heads out for the whole day, links several descents and climbs back up on forest tracks. It suits those who prefer a tough, adjustable bike to a light one, and who want to ride the Montagne Noire as happily as the Pyrenees on holiday.

The LVR workshop view

An alloy frame that adjusts like a race frame. The Fuel LX 9 is built on Alpha NEXT Platinum aluminium, the highest grade of Trek's mountain bike alloys (above Alpha Platinum and Alpha Silver). What sets it apart is the kinematics: the progression can be changed, the rocker link and lower shock mount can be swapped, and the ABP pivot on the rear axle keeps the suspension working under braking.

Put simply: this frame adapts to your riding instead of imposing its own. It is heavier than the OCLV Mountain carbon of the 9.8, but it is more forgiving of impacts and easier to repair.

On a six-hour ride, reliability counts as much as performance. The Eagle 90 T-Type drivetrain mounts directly on the frame dropout, without a conventional derailleur hanger, making it less sensitive to impacts. Its steel crankset with a 30-tooth chainring takes rock strikes in its stride.

On long climbs, the 30 x 52 lets you keep a reasonable cadence. On the descents, the Bontrager Line Dropper post frees up all the space under your hips so you can move around on the bike. The in-frame storage holds a spare inner tube and a tool.

Which Fuel should you choose?

Our take: for long days, the LX 9 Eagle 90 remains simpler to live with than the LX 9 X0 AXS, with no battery to charge. The Fuel MX 9 Eagle 90 saves 600 g, but with 10 mm less suspension travel.
