Fuel EX 5 is the gateway to full suspension trail bikes. A 140mm fork and 130mm of rear travel, a Shimano 1x10 drivetrain, a dropper post for getting low on descents, and Shimano hydraulic disc brakes make Fuel EX 5 a high-value, high-performance mountain bike with exceptional versatility. It's right for you if... You're ready to go full suspension, and you want a versatile trail bike at a great value. You want a ride that's sure-footed, capable, and responsive so you can stay in control no matter where you're riding. The tech you get A lightweight Alpha Platinum Aluminum frame with internal cable routing, a Straight Shot down tube for extra stiffness in the rough, and a Knock Block steerer stop to protect against spinning bars. A 140mm RockShox Recon RL fork, 130mm of rear travel with a RockShox Deluxe Select Plus shock, a durable 10-speed Shimano Deore drivetrain, dropper post, and hydraulic disc brakes. The final word Full suspension performance without the sticker shock. Fuel EX 5 has the same frame and suspension tech found on our higher-end alloy Fuel EX models. Quality RockShox suspension, a dropper post, and a Shimano 1x10 drivetrain make for an ideal introduction to the world of full suspension trail riding. Why you'll love it - You're getting awesome features and the latest mountain bike innovations at an exceptional value - It has the capability of far more expensive trail bikes: it shreds singletrack and can even handle marathon races - The dropper post lets you lower your saddle on the fly so it's out of the way on descents - The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring - We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5-inch wheels, S frames get to choose between 27.5-inch or 29-inch, and sizes M to XL get 29-inch wheels
