Velodrome/Fixed Gear Road As pure a bike as you'll ever find, the Langster likes fast friends. Clearly a bike with one gear and no brakes is not for the faint of heart. That's OK, though, because you're not worried about spinning it out down the backside of a small roller or having a little water splash up off the back tire. You're more about the hum a properly tuned fixed-gear bike makes when brought up to speed, the roller-coaster-gone-off-the-tracks feeling of dropping down the banking with a lap to go, or cranking past fellow riders on a shallow climb.
