Factory Description
Deep-dish pizza, the Sears Tower and the Super Bowl Shuffle are all things Chicago, just like Specialized's Langster of the same name. Its light, responsive A1 Premium aluminum frame and one-speed gearing are ideal for aspiring track racers, urban commuters and for those looking for a bike that is a pure joy to ride. The dual-pivot brakes give you peace of mind and the durable Specialized components mean you'll enjoy this sweet machine for years to come. Plus, the flip-flop hub gives you the option of going to a fixed gear (no coasting), too.
