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

Overview

You ride more than one type of trail, so you're searching for a versatile trail bike platform that will give you the best bones for a ride that's quick and fun on a variety of terrain.

A lightweight Alpha Platinum Aluminum frame with 130mm of travel and Mino Link adjustable geometry, 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 AL is burly enough for big features but agile enough for fast singletrack sessions. It's a great all-around frameset for the mountain biker who wants to explore all kinds of terrain on a single full suspension trail bike.

RE:aktiv is firm when you're pedaling and plush over bumps
This bike is perfect for shredding singletrack, hitting drops, and pushing your limits on the longest days
Control Freak cable management makes it easy to run any combination of controls, like front brake on the right or internal droppers
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.

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 technology gives you firm support for efficient pedaling that instantly gives way for smooth control when the trail turns rough.

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.

Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.

The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
