Back Issue | Group Test: Trek Fuel EX 9 29 Review
The Fuel EX is one of the most popular Trek models. The numerous model and spec versions available and the option to configure your own bike are proof of this.
For this test the € 3,999 Fuel EX 9 29 was chosen to go head-to-head with the bikes of the competition.

Visually, the Fuel EX 9 managed to convince the test crew straight away.
The beautifully formed and polished aluminium frame is a big part of this.
The components used are a slightly less emotional affair: however, a complete Shimano XT drivetrain and brakes, as well as a Fox Factory suspension set-up and a RockShox Reverb Stealth seatpost will always win over on performance alone.
The rest of the parts, such as bars, stem, wheels, and tyres are all from the in-house Bontrager brand and reinforce the well-chosen overall spec.
With a weight of 13.5kg, the Fuel EX is only mid-field in the test group; climbing, however, you wouldn’t think so. The bike has tremendous power — not just thanks to the lightly-stretched rider position and the effective Fox CTD suspension parts, which already complete eliminate bob even in the trail setting. Even really steep climbs become less of a horror as the front wheel stays planted on the ground. The rear end of the Trek is kept under control with a DRCV shock developed with Fox. This is plush as velvet and still controls bigger hits well in spite of the shorter 120mm travel. An effective end-progression avoids unpleasant rear bottom-outs. The Fox 32 Float Factory suspension fork performs just as well and was loved by the testers for its great action and plentiful feedback, especially in the mid-travel range.
The potent suspension and coherent geometry combine for first class handling.
The Fuel EX can be navigated with precision and transfers line changes directly and willingly. In spite of the somewhat steep 69.5° head tube angle, it never feels nervous at high speeds, and with a super-low standover height one always feels confident and in control.
The relatively wide 2.3″ Bontrager XR3 Team tyres fit the character of the bike well, as they offer both masses of grip and outstandingly low rolling resistance.
Clever – The chainstay protector doesn’t just keep the paint looking good — it also serves as a guide for the shift cable.
Grippy – The Bontrager XR3 Team tyres offer great grip on rocky or forest surfaces. The thick carcass makes tubeless fitting straightforward.
Move on up – Because of the extremely short steerer tube, we decided to put extra spacers under the stem. This adds confidence and a more balanced ride, especially on steep descents.
High grade – The priority to invest in a high-quality suspension set-up really pays off. Front and rear suspensions harmonise very well and also offer great initial action and perfect feedback.
Rock guard – The thick, replaceable protector should protect the down tube from any trail debris.
Conclusion:
With the Fuel EX 9 29, Trek have managed to create an incredibly versatile 29er. A real rocket on the climbs and yet precise and confident when descending, whatever the trail throws at you this bike is ready. The clear test-winner.
