Trek Fuel EX

Trek’s 2023 Fuel EX Reviewed: Options, Options, Options…

Trek’s 2023 Fuel EX has just been made public and it has received a massive overhaul. The mid travel/duty trail bike gets a 10mm travel bump front and rear and now sits at 150mm front and 140mm rear. However, there is plenty more to the story…It can accept a 27.5″ rear wheel if you up the fork travel to 160mm, and it also sees an adjustable head angle and adjustable rear shock progression. Read on for the full scoop or watch the video for the review (English subtitles).


The route in the video can be downloaded here.

Details Trek Fuel EX

  • 29″ front and rear with Mullet option
  • Size specific seat stays
  • Adjustable geometry via Mino Link flip chip
  • Adjustable head angle via angleset sold separately
  • Longer reach, slacker head tube, steeper seat tube
  • Fully guided cable/hose routing
  • Adjustable leverage rate via flip chip
  • Air or coil shock compatible
  • Integrated downtube storage on carbon fiber and alloy frames

Internal storage is available on both Aluminum and Carbon Fiber framesets.

Trek will be selling headset cups that allow you to alter your head angle plus or minus one degree without affecting bottom bracket height.

The flip chip in the lower shock eyelet doesn’t affect geometry, but it does change from a more linear to a more progressive setting. As the Fuel EX works with both Coil and Air sprung shocks this is ideal as it helps the rider fine tune the kinematics to the shock of choice.

ABP remains…

Full length, removable downtube cover.

The “mino-link” allows for geometry adjustments of +/- .5º head/seat angle and +/- 8mm BB


**Note the two options below both are listed as “low”. This was a typo from Trek’s press office. The upper chart is low, and the lower chart is high.**

Trek will offer the bike in XS, S, M, L and XXL sizing and the frameset will be offered as a standalone option in both Aluminum and Carbon with a full lineup of Aluminum and Carbon complete bikes with a broad range of specs.


We’re working on getting a Fuel EX for long term testing, so keep your eyes peeled. In the meantime, hit the link below for all of the spec options and pricing.
