Musically speaking, Allegro means quick and lively. Which exactly characterizes the spirit of our Allegros: tness bikes that are lively, quick and seriously fun to ride. Our Allegros blend the speed and ef ciency of a road bike with the heads up riding position many people prefer. The combination of road bike drivetrains, at bar shifters, lightweight aluminum frame and carbon fork means you can Gran Fondo it on the weekend, then race through traf c during the week.
