About the Fuel EX

Quiver Killer Trail Bike

• Capable on all trails; it’s intended to be your only MTB
• Poppy, supportive mid-travel takes hits and excels in corners
• Modern geometry puts you in position to climb and descend with conviction
• Flip chip allows customizable geometry for your trails
• New models feature integrated downtube storage

The Fuel EX is the definition of a modern trail bike, and is Trek’s most well-rounded MTB. With more travel than the Top Fuel and less travel than the Remedy, it’s capable on descents and quick on climbs. Meet your ticket to fast and fun.

About Trek

Trek Bicycles set out to change minds—top-notch bikes do come from America, not just Europe. Trek makes over a million bikes a year and is still simmering with homegrown American pride.

The non-drive side chainstay was professionally repaired by Broken Carbon in Boulder, CO, and that repair comes with their 5-year limited warranty.

Highlights:
- New WTB ST i35 wheelset.
- New front & rear brake rotors & front brake pads for more stopping power.
- New FSA chain & SunRace cassette for crisp shifting.
- New grips for improved comfort & control.
- Tuned front & rear brakes, firming up lever pull & creating consistent grab.
- New shifter cable & housing, pro-tuned to optimize crisp shifting.

Master Mechanic's Notes:
- Small scratches on the top tube.
- Small paint chips on the chainstays & backside of the seat tube.
- Small scratches on the non-drive side fork stanchion.
- Small scratches on the frame, rear triangle, & fork lower legs.
