Who is it for?

For the tall mountain biker, from 188 to 203 cm, who often struggles to find a carbon enduro bike in their size and wants a seatpost long enough to pedal properly. It also suits medium-height riders looking for a complete, uncompromising bike.

The LVR workshop view

OCLV carbon, Trek's signature. For its mountain bikes, Trek adapts its OCLV process into a Mountain version: the fibres are oriented and reinforced where an enduro frame takes the hits, under the down tube and around the pivots. The result is a frame that is lighter than aluminium without being more fragile, covered by Trek's lifetime warranty. On the Gen 7 Fuel platform, the frame kit difference reaches 1.64 kg in size M according to Trek (3.31 kg versus 4.95 kg, measured on the Fuel EX).

	OCLV Mountain (Fuel LX 9.8 / 9.9)	Alpha NEXT Platinum (Fuel LX 9)	Alpha Silver (Marlin)
Level	Trek's most advanced mountain bike carbon	Higher-grade MTB aluminium	Entry-level aluminium
Construction	OCLV layers reinforced in impact zones	Hydroforming, neat welds	Standard tubes
Complete Fuel LX (M)	15.97 kg (9.8 XT Di2)	17.79 kg (9 XT)	not applicable
What it means	1.82 kg less to haul uphill	Heavier, more affordable	Hardtail range

In short: 15.97 kg in size M for a 160 / 170 mm coil-sprung bike is the lowest published weight in the whole Fuel LX family. Compared with the aluminium Fuel LX 9 XT, the 1.82 kg difference comes from the carbon frame but also from the Di2 drivetrain, which is lighter than the cable version.

On sizes L, XL and XXL, Trek fits a Bontrager Line Dropper with 200 mm of travel: the saddle can drop right out of the way on descents while returning to the correct height for long climbs. For a tall rider, that is the difference between an efficient pedalling position and a saddle that is always too low.

A heavy or tall rider works the suspension harder: the DHX2 spring is chosen according to weight, and the Fox 38 fork is set with air pressure. We start from your measurements to find the right combination, then adjust the sag after a first ride.

Which Fuel should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel MX 9 XT	Alpha NEXT Platinum alloy	150 / 160 mm	Mechanical Shimano XT 1x12	16.91 kg
Fuel LX 9 XT	Alpha NEXT Platinum alloy	160 / 170 mm	Mechanical Shimano XT 1x12	17.79 kg
Fuel LX 9.8 XT Di2	OCLV Mountain carbon	160 / 170 mm	Shimano XT Di2 1x12	15.97 kg
Slash 9.8 XT Di2	OCLV Mountain carbon	170 / 170 mm	Shimano XT Di2 1x12	16.63 kg

Our take: in every size, this 9.8 XT Di2 keeps 160/170 mm; its reference weight is 15.97 kg in M. The alloy Fuel LX 9 XT weighs 17.79 kg, and the Slash 9.8 XT Di2 goes up to 16.63 kg for 10 mm more at the rear.

LVR sizing advice

The Fuel LX is chosen first according to the rider's height: between two sizes, the smaller one makes the bike more playful in hairpins, the larger one more stable at high speed. Dropper post travel increases with size.

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
