Trek Fuel+ EX 9.8 Eagle 90 Carbon Smoke: the companion for long days in the mountains

Designed for big loops, the Trek Fuel+ EX 9.8 Eagle 90 Gen 2 combines a 580 Wh TQ battery, a 60 Nm HPR60 motor, a SRAM 10-52 cassette and RockShox Ultimate suspension with 145 mm at the rear and 150 mm up front. Its frame is OCLV Mountain carbon and Trek quotes 20.38 kg in size M. The Carbon Smoke/Lithium Grey Marble evokes smoked carbon fibre, veined with a lighter lithium grey.

Technical specifications

Who is it for?

For the mountain biker who loves full days in the mountains, with plenty of climbing and varied descents, and who wants to manage their effort rather than suffer on the climbs. It will suit anyone who rides in a group with fitter riders.

The LVR workshop view

OCLV carbon, Trek's signature. Behind the OCLV acronym lies a process of curing the carbon plies under high pressure to eliminate micro-voids. For mountain biking, Trek developed a Mountain version whose layup prioritises impact resistance. On this Fuel+ EX 9.8 Eagle 90, the frame features an adjustable head angle and adjustable progression, and carries a lifetime warranty.

Put simply: the 9.8 Eagle 90 is the Fuel+ EX that puts suspension first, with the same RockShox Ultimate pairing as the 9.9, a mechanical drivetrain and alloy wheels. It weighs 20.38 kg in M according to Trek.

On a long ride, the key is to manage the assist: an economy mode on rolling climbs, more help on the steep ramps, and you save battery for the end of the day. The large 52-tooth sprocket lets you keep a high cadence, which eases the strain on both your legs and the motor on the tracks of the Espinouse.

The removable battery is easy to charge at your holiday cottage or at home. To look after it, avoid leaving it in a hot car in summer and store it at half charge during the months you are not riding. Assist cuts out at 25 km/h, as on all European e-bikes, with a 250 W nominal motor.

Which Fuel+ should you choose?

Our take: at 20.38 kg in M, the 9.8 Eagle 90 is only 280 g heavier than the 9.8 XT (20.10 kg), for RockShox Ultimate suspension. The previous-generation Fuel EXe 9.7 weighs 19.33 kg but with only a 360 Wh battery.
