FSA's Metropolis Patterson 2-Speed crankset has a patented planetary gearing system providing a 1.6-to-1 gear ratio equivalent to having both 45- and 28-tooth chainrings. The Patterson allows instantaneous gear changes under load and works with many shifter options. Upgrade your single-speed with greater gear range or simplify your geared bike. However you use it, the Patterson crankset works beautifully and looks great!
