Trek's Fuel EX line has exactly what the rest of the mountain bike world has been chasing: Award-winning performance.

The Fuel EX 8 29 is a rolling technology demonstrator. Everything that Trek does well in mountain bikes, you'll find on the Fuel EX 8. A rugged, super-strong frame built with Trek's hydroformed Alpha Platinum aluminum ensures immediate power delivery and suspension response. A press-fit PF92 bottom bracket keeps the crankset flex-free, while a tapered head tube helps keep the front wheel aimed where you point it. Need a world-class suspension for rock gardens and root "fun houses"? Look no further than the Fuel EX 8's Active Braking Pivot (or ABP) rear suspension geometry. Hard braking won't stiffen up the ABP rear triangle, no matter how ugly the descents get! 130mm of travel lets you take on hairy trail networks and fast descents with confidence. The rear shock is installed in a Full Floater mount, making the Fuel EX more responsive to washboard surfaces and hard landings alike. A one-piece alloy EVO rear suspension link keeps the rear shock from binding during technical turns. The rear shock itself is an air-adjustable Fox Performance Float EVOL unit with Trek's exclusive RE:aktiv 3-position damper. With the ability to bring almost "bottomless" suspension travel to the Fuel EX 8, the rear ABP suspension and Fox shock helps keep the rear tire planted. An air-adjustable Fox Rhythm 34 Float suspension fork does control duties up front with 130mm of travel, while the front hub's thru-axle adds even more razor-sharpness to the bike's overall handling. In case the trail gets a little too gnarly, Trek has your back with a Knock Block steerer stop in the headset. Spinning forks and damaged down tubes are a thing of the past, and the new, uncurved down tube adds a bit more torsional strength to the Fuel EX 8's long list of qualities.

SRAM's 12-speed Eagle GX shifters and SRAM Eagle GX Roller Bearing Clutch derailleur are paired for perfect operation in muddy and messy conditions, even under hard pedaling loads. A  single-ring Truvativ Descendant crankset with a 32T chainring and SRAM Eagle 10-50T cassette boasts a massive gearing range for roller-coaster singletrack. Reigning in speed is the job of a set of Shimano Deore hydraulic disc brakes for effortless stopping power, rain or shine. Bontrager Line Comp 30 alloy wheels are tubeless-ready, and are shod with Bontrager's 29x2.40" XR4 Team Issue tires for confident grip on technical trails. Boost110/148 hubs add lateral strength to the Fuel EX 8's wheelset. Bontrager's latest alloy Line 35mm stem and 35mm clamp diameter handlebars are ultra-strong for improved handling. A Bontrager Line alloy dropper post can get the Bontrager Arvada saddle out of the way with the press of a bar-mounted remote lever.
