Specialized's Langster is built with a lightweight, responsive A1 Premium aluminum frame and FACT carbon fork with track geometry so you can race it in the velodrome or rip it in the streets. The 48/17 one-speed gearing with a flip-flop rear hub is ideal for training, riding around town and even commuting. Dual-pivot brakes are included because sometimes you need to stop quickly, and the aluminum Specialized components mean you'll enjoy this sweet machine for years to come.
