The best in Trek trail bike frame tech, a full OCLV Mountain Carbon frame, and 130mm of rear travel with a FOX Factory shock make Fuel EX C the ideal start for a dream trail bike or endurance race bike that's burly enough to go big on gnarly descents but quick enough to fly through the local singletrack circuit.

The tech you get
A light and stiff full OCLV Mountain Carbon frame, a FOX Performance shock with Trek's exclusive RE:aktiv damper, and an included Bontrager Line stem and Knock Block headset that prevents damage to the frame from spinning handlebars and fork crowns. Built for a PF92 bottom bracket and a 140mm fork.

Fuel EX C is a frameset that excels in all-mountain riding, and it's the best all-around option for riders who want a single versatile, high-performance ride that rips it up on every trail.
Why you'll love it
- A full OCLV Mountain Carbon frame makes for a ride that's light on the climbs and trail-tough on rough descents
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- This bike is perfect for shredding singletrack, hitting drops, and pushing your limits in multi-stage and marathon events
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- We expanded our size range from XS through XL to ensure a better fit for all riders
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.
