Musically speaking, Allegro means quick and lively, which exactly characterizes the spirit of Jamis’ Allegros: fitness bikes that are lively, quick, and seriously fun to ride. Allegro blends the speed and efficiency of a road bike with the heads-up riding position many people prefer. It has double-wall alloy rims and fast, 700c tires that slice through the miles with ease and linear pull brakes that bring you to a controlled stop on a dime. The combination of a 21-speed road bike drivetrain, flat bar shifters, and lightweight aluminum frame means you can Gran Fondo it on the weekend, then race through traffic during the week.
