Trek Fuel EX 7

Fuel EX is a legendary bike that's Trek's top selling and best loved all around line of bikes for nearly a decade. Capable on almost every trail, the 7 has higher end parts and a completely tubeless setup for less weight and more traction.

With SRAM's most current 1x12 NX Eagle drivetrain powering a light yet stiff alloy frame, a 140mm RockShox fork with a DebonAir spring for better small-bump compliance, and a FOX Performance Float EVOL fork, light fast Bontrager Line Comp 30 wheels with tubeless tires and a dropper post, it's ready to roll out of the box.


  1. Higher end parts you won't outgrow right away as your skills progress.
  2. A solid trail bike that's ready for just about any style trail.
  3. Dropper post lets you get your saddle out of the way on descents.
  4. Wide Line Comp 30 wheels for more traction and control.
  5. Appropriately sized 27.5˝ wheels for the XS frame.
