Technical specifications

Who is it for?

For the demanding rider who wants the best kit in the range from day one, with no parts to replace in the first few months. It is aimed at mountain bikers who ride a lot, look after their equipment and know how to make the most of high-end brakes and wheels.

The LVR workshop view

OCLV carbon, Trek's signature. OCLV carbon is born from a hot compaction process that eliminates voids between the fibres: the sounder the laminate, the less material is needed for a given stiffness. The OCLV Mountain variant applies this principle to durability against the impacts typical of mountain biking. On the Fuel+ LX 9.9, this frame gets the most refined parts in the family, a wireless drivetrain, Maven Silver brakes and a carbon-railed saddle, and carries a Trek lifetime warranty.

Put simply: the 9.9 X0 AXS is the best-equipped Fuel+ LX: Line Pro 30 wheels, Maven Silver brakes, SRAM wireless drivetrain, Fox Transfer Neo dropper and carbon handlebar, built around RockShox Ultimate suspension. Trek does not give its weight; the 9.8 Eagle 90, with an identical frame and motor, serves as the benchmark at 20.88 kg in M.

The Line Pro 30 wheels give more direct steering than the aluminium Line Comp 30 wheels on the 9.8 models: the bike follows the intended line on off-camber sections and through ruts. The Maven Silver brakes offer more adjustment than the Bronze, notably for setting the lever position and bite point, a real plus on the long descents of the Caroux.

The Aeolus Pro saddle with carbon rails and the ERA carbon handlebar lighten the contact points and filter out some of the vibration. On the assist side, the TQ follows the rules for European e-bikes: 250 W nominal, no more help above 25 km/h; that is enough to climb quickly while keeping an agile bike.

Which Fuel+ should you choose?

Our take: compared with the RockShox Fuel+ LX 9.8 Eagle 90, the suspension is identical: the difference lies in the wheels, brakes, wireless drivetrain and dropper. The Slash+ 9.9, the other high-end TQ enduro bike, weighs 21.83 kg in M with a 27.5-inch rear wheel.
