With the big-wheel mile crushing of an XC bike and the confidence of an aggressive trail bike, Trek's Fuel EX 8 29 trounces whatever trails you have in mind. This 29er boasts Trek's Alpha aluminum frame with G2 geometry. Stiffness means precise handling, so you're equipped with Trek's E2 head tube and a 142x12 rear through axle, plus Trek's ABP and Full Floater suspension to keep your rear suspension active and controlled even when you're braking. That suspension devours hits to the tune of 120mm of front and rear travel, controlled by Fox's technology and enhanced with Trek's Re:activ tech out back. The rest of the parts are just as dialed. This outstanding bike is built up with tubeless-ready Bontrager wheels and tires, sure-stopping Shimano discs, and a Shimano 2x10 drivetrain for crisp, quick shifts every time. The Fuel EX 8 29 is ready for whatever you have in mind.
