Product Description
2026 Trek Fuel LX 9.8 XT Gen 7 Carbon Trail/Enduro Mountain
The Fuel LX 9.8 XT Gen 7 is a rowdy carbon trail bike built to slay steep descents and blast through wheel-gobbling terrain. Its high-performance OCLV Mountain Carbon frame partners with a premium Fox Factory 38 fork and DHX2 coil shock (170mm front/160mm rear) for going all-out on the wiliest lines on the mountain. This build is powered by the legendary mechanical Shimano XT 12-speed drivetrain for reliable, crisp shifting without the fuss of electronics, paired with high-modulation 4-piston XT M8200 brakes for elite stopping power.
