Fuel EX

The Gen 7 Fuel EX lineup spans a wide price range, split between Alpha Platinum aluminum frames and OCLV Mountain Carbon options. The entry-level EX 5 provides a basic RockShox Recon fork and Shimano Deore drivetrain, but the alloy EX 8 is widely considered the value sweet spot. It pairs a Fox 36 Rhythm fork and Float X shock with SRAM's wireless Eagle 70 Transmission and DB8 four-piston brakes, offering high-end shifting reliability at a mid-tier price.

Moving into the carbon models, the 9.8 and 9.9 tiers introduce premium suspension, including Fox Factory Grip X2 or RockShox Lyrik Ultimate forks, alongside carbon wheels and handlebars. Drivetrain options at the upper end split between Shimano XT (mechanical or Di2) and SRAM's higher-tier Eagle 90 and X0 Transmissions. Braking also upgrades to SRAM Maven or Shimano XT four-piston calipers for increased stopping power. While the modular frame design allows riders to convert any EX build into an MX or LX configuration, doing so requires purchasing separate rocker links, lower shock mounts, and potentially new suspension components.

Reviewers consistently characterize the Gen 7 Fuel EX as a highly composed descender that masks its substantial weight with sophisticated suspension. The revised kinematics and Active Braking Pivot design provide excellent traction, keeping the rear wheel "glued to the ground" (Flow Mountain Bike) over rapid-fire hits and heavy braking. Testers found the initial suspension stroke offers a "useful, helpful, comfortable bit of ease" (Singletrackworld) that prevents the bike from feeling skittish on technical trails.

When pointed downhill, the bike's mass becomes an asset. The heavy frame delivers an "unshakeably anchored" (Mountain Bike Rider) sensation that mimics much larger gravity bikes, making it a "rocket on steep descents" (Cycling Magazine). However, that same weight creates noticeable inertia on flat terrain and out of slow corners. While it excels at technical, traction-limited climbing, testers noted it requires more effort to accelerate than lighter trail competitors.

The primary criticism across reviews centers on the stock Bontrager Brevard tires, which testers found too flimsy for the bike's aggressive capabilities, frequently suffering punctures. Additionally, some reviewers experienced cable rattle on the alloy frames and an internal rattle on the Fox 36 Rhythm fork equipped on the EX 8 build.
