Trek Fuel+ LX 9.8 XT Di2 Carbon Smoke: for those who live for the descent

With 170 mm up front, 160 mm at the rear on a coil shock and 2.5-inch Maxxis tyres with EXO+ casings, the Trek Fuel+ LX 9.8 XT Di2 is a descent-focused assisted enduro bike. TQ HPR60, 580 Wh battery, wireless XT Di2 drivetrain and XT brakes on 200 mm rotors complete an OCLV Mountain carbon frame. Trek has not published a weight for this version; benchmark: Fuel+ LX 9.8 Eagle 90, 20.88 kg in size M. The Carbon Smoke/Lithium Grey Marble is a smoky grey veined with light grey.

Technical specifications

Who is it for?

For the committed rider who is looking above all for speed and confidence on steep slopes, drops and rock gardens, the climb being just a necessary step that the motor makes shorter. It will appeal to mountain bikers who ride the enduro tracks of the Hérault and want a bike ready for them straight out of the box.

The LVR workshop view

OCLV carbon, Trek's signature. Behind the OCLV acronym lies a moulding process Trek has been perfecting for more than thirty years: heat and pressure for carbon with no porosity. For mountain biking, the Mountain variant is engineered to withstand rock strikes and crashes, which matters on an assisted bike that goes faster and for longer through rock gardens. The Fuel+ LX adds guided internal routing that neatly tidies away the housing and motor wiring, plus the Trek lifetime warranty.

Put simply: compared with the 9.8 XT, only one part changes: the wireless XT Di2 M8260 derailleur replaces the cable-operated model; the Fox 38, DHX2, XT brakes and wheels are shared. No official weight for this version; the benchmark remains the Fuel+ LX 9.8 Eagle 90, 20.88 kg in M.

The pairing of an Assegai up front and a Minion DHR II at the rear, with reinforced EXO+ casings, is a proven enduro setup: cornering grip and straight-line braking, with better resistance to pinch flats. Fitted tubeless, it can run lower pressures for even more grip on rock slabs and roots.

Four pistons and 200 mm rotors front and rear: the XT M8220 brakes stop hard and without fade, an asset when the speed and mass of an e-MTB add up. The motor's assist cuts out at 25 km/h, with 250 W nominal, as for any European e-bike; on the descents, the suspension does the work.

Which Fuel+ should you choose?

Our take: for pure descending, this 9.8 XT Di2 shares its suspension and tyres with the 9.8 XT; the Slash+ 9.9 remains the alternative with a mixed-wheel setup, at 21.83 kg in M. The Fuel+ MX 9.8 XT Di2 gives up 10 mm at each end for 19.79 kg.
