Trek Fuel LX 9.8 Eagle 90 Purple Phaze: the carbon enduro bike up to XXL

With its five sizes from S to XXL, the Trek Fuel LX 9.8 Eagle 90 Gen 7 welcomes riders from 155 to 203 cm on an OCLV Mountain carbon frame, with a 170 mm RockShox ZEB Ultimate fork and a 160 mm Vivid Ultimate. Weight not published by Trek for this version; the 9.8 XT Di2 on the same frame weighs 15.97 kg in a size M. The Purple Phaze / Amethyst Marble colourway blends a shifting purple with amethyst marbling.

Who is it for?

Very tall riders, often poorly served in enduro, find a carbon enduro bike in their size here. This Fuel LX also suits anyone who wants a light carbon frame with first-rate suspension, from 155 cm.

The LVR workshop view

OCLV Mountain carbon, Trek's mountain bike signature. OCLV is Trek's carbon process; its Mountain version is tuned for impact resistance rather than weight saving alone. The Fuel LX 9.8 benefits with a frame lighter than the Alpha NEXT Platinum alloy of the LX 9, the same adjustable kinematics, a UDH hanger and Trek's lifetime warranty on the frame.

	OCLV Mountain (Fuel LX 9.8)	Alpha NEXT Platinum (Fuel LX 9)	OCLV Mountain (Slash 9.8)
Level	Trek's mountain bike carbon, lifetime warranty	Trek's best mountain bike aluminium	Same carbon, more aggressive bike
Construction	OCLV layup tuned to absorb impacts	Alloy engineered for strength	OCLV layup, 170 mm at the rear
Reference bike	Gen 7 carbon Fuel EX frameset: 3.31 kg (M)	Gen 7 alloy Fuel EX frameset: 4.95 kg (M)	Slash 9.8 XT Di2: 16.63 kg (M)
What it means	About 1.6 kg less on the frameset	Heavier, more affordable	More travel, less versatile

Put simply: the 9.8 Eagle 90 is the most direct way to get a carbon Fuel LX. The drivetrain stays mechanical and robust; the weight is not published, but the 9.8 XT Di2 on the same frame weighs 15.97 kg in M.

In XXL, Trek fits a 200 mm dropper post, as in L and XL, to keep maximum clearance on the descents. A large carbon frame keeps good stiffness without getting as heavy as an alloy frame of the same size. We check saddle height and handlebar position with you.

For a tall and often heavy rider, the ZEB is a good choice: its large-diameter stanchions ensure precise steering. The Vivid Ultimate is set according to your weight, and the four-piston Maven Bronze brakes provide the power needed.

Which Fuel should you choose?

Model	Frame	Drivetrain	Travel rear / front	Weight (M)
Fuel LX 9 Eagle 90	Alpha NEXT Platinum alloy	Mechanical SRAM Eagle 90	160 / 170 mm	17.38 kg
Fuel LX 9.8 Eagle 90	OCLV Mountain carbon	Mechanical SRAM Eagle 90	160 / 170 mm	n/a (reference 15.97 kg)
Fuel LX 9.8 XT Di2	OCLV Mountain carbon	Wireless Shimano XT Di2	160 / 170 mm	15.97 kg
Slash 9.8 XT Di2	OCLV Mountain carbon	Wireless Shimano XT Di2	170 / 170 mm	16.63 kg

Our take: offered up to XXL like the other carbon Fuel LX models, this 9.8 Eagle 90 is the only one to keep the mechanical SRAM Eagle 90 drivetrain. The LX 9.8 XT Di2 weighs 15.97 kg in M; the alloy LX 9 Eagle 90, 17.38 kg.
