Trek's mountain bike engineers decided there's no such thing as too much grip. The Fuel EX 8 gives you that, plus an outstanding fit!
The Fuel EX 8 WSD was redesigned for 2018 with an eye towards offering as much traction as possible. The tubeless-ready Schwable Nobby Nic Performance tires are now a massive 27.5x2.80", boasting a huge contact patch on the trails. Crumbly surfaces, loose gravel and rock gardens can be attacked with greater confidence. Trek's exclusive Active Braking Pivot -or ABP- rear suspension geometry ensures that the rear tire won't be affected by braking dynamics because the pivot point is the rear thru-axle. This is critical for control, especially when descending a technical trail into a sharp, unforgiving hairpin. The one-piece EVO Link upper suspension link resists torsional stress, allowing the rear shock to operate smoothly. The Full Floater rear shock mount reacts to small trail impacts better, reducing rider fatigue. The Fuel EX 8's handling geometry can be altered by reversing the Mino Link chips found on the EVO Link. When done, the bike's head tube angle can be slackened and the bottom bracket dropped slightly for an even more stable feel on gnarly terrain.
The Fuel EX 8 is built around an Alpha Platinum aluminum frame that keeps overall weight low while retaining plenty of strength to handle rough trails and powerful riders. The frame's fit and design favors female riders better with a shorter standover height and taller head tube. A tapered head tube adds precision to the Fuel EX 8's handling in fast corners, while a PF92 bottom bracket adds flex-free power delivery through the crankset. Clever internal cable routing -known as Control Freak- keeps the bike's cablework out of the dirt while all but eliminating rattle and friction-inducing tight bends. The Straight Shot down tube reduces weight and improves torsional strength further.
The suspension Trek chose for the Fuel EX 8 brings trail-taming control on technical features. The rear air-adjustable Fox Performance Float EVOL shock was tuned with Trek's suspension lab in Southern California along with input from Penske Racing Shocks. The result is a tuneable shock that can react to impacts both large and small, bringing control to a wide range of riding situations. A RE:aktiv 3-position damper allows the rider to tweak the shock adjustment on the fly. Up front, an air-adjustable Fox Rhythm 34 Float suspension fork helps keep the bike where you point it, with 120mm of travel. An adjustable damper knob on the fork crown also allows on-the-fly adjustment. Cool, huh?
The Fuel EX 8's drivetrain is SRAM's latest off-road component breakthrough: 12-speed GX Eagle. That's right, 12 speeds. The need for a front derailler and multiple chainrings are all but eliminated with GX Eagle. A single GX Eagle shift lever and GX Eagle Roller Bearing Clutch rear derailleur do shifting duties, while a 10-50T SRAM cassette and single-ring 32T SRAM Descendant crankset boast a massive gearing range for roller-coaster terrain.
For those massive Schwalbe Nobby Nic tires, SUNringle's tubeless-ready alloy Duroc 40 SL wheels form an excellent partnership. The wide rim keeps the tire's contact profile wide and aggressive, bringing even better grip in fast and twisty singletrack. Helping to keep speed reigned in is a set of SRAM Guide R hydraulic disc brakes.
A Bontrager Drop Line dropper post helps get the Evoke 2 women's saddle out of the way on steep descents with a handlebar-mounted remote lever. An alloy Rhythm Comp stem and headset prevents frame damage in a crash with the aid of a Knock Block headset limiter. That Straight Shot down tube will remain dent-free, even if the rider is a clumsy newbie, thanks to knock Block. An alloy Race Lite handlebar finishes off this amazing off-road challenger.
