Hardtails may not be the first thing that comes to mind when looking to boost your trail riding experience, however, the Specialized Fuse is here to change your mind. The Fuse’s M4 aluminum frame is loaded with smart touches such as a wide-diameter down tube to boost stiffness, a low-slung top tube to provide the needed clearance to throw the bike around on tight trails, and adjustable dropouts that let you run the Fuse geared or single-speed. The dropouts also let you adjust the chainstays by as much as 15 millimeters, lengthening the rear end for more stability or shortening it up for quick, nimble manners. Don't bring a knife to a gun fight, bring some dynamite, lite the Fuse and observe the events and reactions that unfold.
