You want a single carbon trail bike that can take on every adventure, from singletrack to the gnarliest descents and multi-stage endurance events. You prioritize a lightweight frame and performance suspension over the highest-end drivetrain available.
The tech you get
A lightweight and stiff full OCLV Mountain Carbon frame with Carbon Armor, a 140mm FOX Rhythm 34 fork, 130mm of rear travel with a FOX Float Performance rear shock with Trek's exclusive RE:aktiv damper, a wide-range 1x12 SRAM NX/GX Eagle drivetrain, a Bontrager Line dropper post, Tubeless Ready Bontrager Line Comp 30 wheels, and powerful Shimano 4-piston hydraulic disc brakes. An internal storage compartment and Control Freak cable routing add to the bike's capability and sleek look.
The final word
Fuel EX full suspension performance on a lightweight and trail-tough carbon frame makes for a fun and fast ride. This rugged, capable bike sails down descents and helps you hang tough during fatiguing marathon rides.
Why you'll love it
- Don't confuse Fuel EX 9.7 with other value carbon models on the market—this bike provides an outstanding frame and suspension, with a workhorse drivetrain and wheels
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- This bike is perfect for shredding singletrack, hitting drops, and pushing your limits in multi-stage and marathon events
- The shifter-style, underbar remote dropper post lever is super intuitive and easy to use
- We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5-inch wheels, S frames get to choose between 27.5-inch or 29-inch, and sizes M to XL get 29-inch wheels
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
