Trek Fuel+ MX 9.8 Eagle 90 Gloss Navy Smoke: suspension first

OCLV Mountain carbon frame, 170 mm RockShox ZEB Ultimate fork, Vivid Ultimate shock working through 150 mm: the Trek Fuel+ MX 9.8 Eagle 90 puts the essentials into its chassis and entrusts shifting to a cable-operated SRAM Eagle 90. Assist comes from the 60 Nm TQ HPR60, powered by 580 Wh. On the scales, weight not published by Trek for this version, with the 19.79 kg (size M) of the 9.8 XT Di2, which shares the frame and motor, as a point of comparison. Gloss Navy Smoke/Matte Trek Black colourway: a deep navy with smoky, lacquered highlights, set off by matt black sections.

Who is it for?

For the mountain biker who wants to get into the MX series by prioritising what you feel on the trail, the suspension and the frame, rather than drivetrain electronics.

The LVR workshop view

OCLV carbon, Trek's signature. With OCLV, Trek puts its fibres through a cycle of pressure and heat that leaves almost no porosity in the composite, a guarantee of long-term strength. Its Mountain version is designed for brutal use: hard impacts, flying stones and crashes. On the Fuel+ MX 9.8 Eagle 90, the gateway to the MX series, you get exactly the same carbon frame, its removable battery housing and the Trek lifetime warranty.

	Fuel+ (TQ HPR60)	Fuel EXe (TQ HPR50)	Rail+ (Bosch CX)
Torque	60 Nm	50 Nm	Bosch Performance Line CX
Battery	580 Wh, removable	360 Wh	800 Wh
Comparison weight (M)	19.79 kg (MX 9.8 XT Di2)	19.33 kg (EXe 9.7)	23.73 kg (Rail+ 9.7)
What you gain	Lively bike, enough assist for all-mountain	Lightness, less reserve	Maximum reserve, more inertia

Put simply: the 9.8 Eagle 90 spends its budget on RockShox Ultimate suspension, a 170 mm ZEB fork and Vivid shock, and keeps a mechanical SRAM drivetrain that is simple to maintain. To gauge its unpublished weight, refer to the Fuel+ MX 9.8 XT Di2 with an identical frame and motor: 19.79 kg in M.

The SRAM Eagle 90 T-Type drivetrain mounts directly to the frame's UDH hanger, making it more resistant to rock strikes than a derailleur on a conventional hanger. Its 10-52 cassette and cable operation remain simple to adjust, and wear parts are easy to replace.

On the suspension side, the ZEB Ultimate and Vivid Ultimate are the same as on the 9.9 X0 AXS, at the top of the RockShox range, adjustable in compression and rebound. As for the motor, its push stops at 25 km/h and its nominal power remains 250 W: that is the European legal framework for e-bikes.

Which Fuel+ should you choose?

Model	Motor / battery	Rear / front travel	Drivetrain	Weight (M)
Fuel+ EX 9.8 Eagle 90	TQ HPR60, 580 Wh	145 / 150 mm	SRAM Eagle 90 T-Type	20.38 kg
Fuel+ MX 9.8 Eagle 90	TQ HPR60, 580 Wh	150 / 170 mm	SRAM Eagle 90 T-Type	not disclosed
Fuel+ MX 9.8 XT Di2	TQ HPR60, 580 Wh	150 / 160 mm	Wireless Shimano XT Di2	19.79 kg
Fuel+ LX 9.8 Eagle 90	TQ HPR60, 580 Wh	160 / 170 mm	SRAM Eagle 90 T-Type	20.88 kg

Our take: same ZEB, same Vivid as on the 9.9 X0 AXS; the difference lies in the wheels (aluminium here, carbon on the 9.9), the handlebar and the derailleur. Compared with the Fuel+ EX 9.8 Eagle 90, quoted at 20.38 kg in M, this MX gains 5 mm of rear travel and 20 mm of fork travel.

LVR sizing advice

On the cusp of two sizes, choose the smaller one if you like to place the bike and jump, the larger one if you mostly ride fast on steep ground. All sizes get the 27.5-inch rear wheel, and the Line Dropper grows from 150 to 200 mm with the frame.

Size	S	M	L	XL	XXL
Rider height (cm)	155-165	165-177	177-188	188-195	195-203
Inseam (cm)	74-78	79-83	84-89	89-91	91-97
Dropper post (mm)	150	170	200	200	200
Front / rear wheels (in)	29 / 27.5	29 / 27.5	29 / 27.5	29 / 27.5	29 / 27.5

Your questions

What does this model weigh?	Weight not published by Trek; the 9.8 XT Di2, on the same platform, weighs 19.79 kg in M.
Eagle 90 or X0 AXS?	The Eagle 90 is cable-operated; the X0 AXS is controlled wirelessly, with a derailleur battery.
Isn't the ZEB overkill?	It is designed for hard-hitting all-mountain and enduro riding; it brings a lot of stability to the front end.
Is the matt black easy to look after?	Yes, with a gentle cleaner and no polishing products.

The LVR Cycles verdict

The gateway to the MX series, investing in RockShox Ultimate suspension and the carbon frame rather than in electronics. The glossy smoky navy over matt black gives it an understated look.

Pros
+ RockShox Ultimate suspension from the 9.9
+ Mechanical drivetrain with no battery
+ Elegant navy and black

Cons
- Weight not published by Trek
- Line Comp 30 alloy wheels
