Trek Fuel EX 9.8 Custom, MD/LG (2023) Deep Smoke


Fuel EX 9.8 is an all-around trail bike that blends the light, smooth ride of a carbon frame with upgraded parts made for hard rides.

This custom Fuel EX 9.8 comes with SRAM GX Mechanical drive train, Blackbird Send 29" Aluminum wheels, Fox Float X rear shock, Lyric Select+ fork and XT 4p brakes.

Why you'll love it

  1. You'll get the lightweight and vibration-damping benefits of a full carbon frame, and geometry built to handle anything
  2. It comes with light and stiff carbon wheels that make quick work of technical terrain and keep you on your line, even when things get hairy
  3. With the adjustable angle headset (angled cups sold separately) and Mino Link, you can choose from six different geometry configurations
  4. Trek expanded its size range to ensure a better fit for all riders and use the best-fitting wheels for each frame size: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M and up get 29˝ wheels

It's right for you

You're chasing long flowy and technical descents, and want to pedal back to the top for more, lap after lap. You want the vibration-damping benefits of a carbon frame and carbon wheels, plus upgraded suspension that smooths out the rough and rowdy.

The final word

Fuel EX 9.8 is the culmination of years of trail riding and progression, with longer front-end geometry for tackling steeper and hairier descents, and a steeper seat tube to keep you perched on climbs. It's equipped with the cherry-picked components you want, like upgraded suspension, carbon wheels, and a SRAM GX drivetrain.
