Why We Like The Specialized Fuse M4 Frame

With nimble handling and fresh confidence the Specialized Fuse M4 Frame provides the snappy, happy responsiveness we want for our trail rides. It's functional and built with an intentional design that lets us enjoy our ride to the fullest extent. Stiffness comes from the wide-diameter down tube, and the low-slung top tube gives us enough clearance to navigate tight trails easily. Adjustable dropouts give us the option to run the Fuse M4 geared or single-speed, and those dropouts also offer the option to adjust the chainstays by up to 15 millimeters. This lengthens the rear end for increased stability, and shortening it up gives us a nice agile touch.
