The Sarthe is a road racing bike. It has more gears than I know what to do with. I believe you meant the Fillmore? And the Fillmore is advertised as a fixed gear road bike, while the Pista and Langster are more track-oriented in their geometry (the Pista a bit more so), so they can be accurately referred to as "track bikes."
