Fuel EX C Gen 5 Frameset - Trek Bikes (CA)

Overview

You're after your own version of a holy grail mountain bike build. You know how you want to ride, and you know which parts you need to do it. You want the best all-around trail bike frame we offer, because you know that a great build starts with a great frame.

A full OCLV Mountain carbon frame with internal storage, 130mm of travel and Mino Link adjustable geometry, a FOX Factory Float shock with Trek's efficient RE:aktiv with Thru Shaft damper, and an included Bontrager Line Pro 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.

A full OCLV Mountain Carbon frame and FOX Factory shock give you a major head start on a build that will be the envy of all other trail bikes. It's the best all-around option for riders who want a single versatile, high-performance ride that rips it up on every trail.

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

"Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedaling, and to pump and pop off when you're playing."

"Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better at it."

"Thanks to its burlier components, increased travel, and more aggressive geometry, it has become more of a shredder than ever! More performance, fun, and trail prowess."

"In a world where most new full-suspension mountain bikes are amazing, Fuel EX stands apart as even more than that."

Choose from the lighter 130/140mm Fuel EX Gen 5 with better parts for the price or the more robust 140/150mm Fuel EX Gen 6 with more adjustability.

Features

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.

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

RE:aktiv with Thru Shaft gives you unmatched grip and control with a shock that reacts to the terrain faster than anything else out there.

Trek's Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
