Scott Speedster 20

The Speedster is a rare breed: an affordable, aerodynamically designed bike. Borrowing from Scott's flagship Foil (bladed carbon fork, internal cable routing, aero downtube), the Speedster lives up to its name. It accelerates quickly before settling into a smooth, stable ride. Touches such as better-than-entry-level wheels and a slightly relaxed ride make it ideal for everything from a breakaway to a cruise to the cafe. [$1,400; scott-sports.com]
