Felt may have built the world's fastest, most aerodynamic road bike ever in the AR. After countless hours of computer and wind-tunnel time, it debuted at the 2008 Tour de France and immediately made its mark with a second-place in Stage 3 under Will Frischkorn after an impressive daylong breakaway. Frischkorn's secret was the AR's amazingly slippery and fast profile with wheel cutouts, internal cable routing, aero seatpost and seamlessly integrated bladed carbon fork. Equally important, depending on wind conditions and terrain, it could save you 58 to 75 seconds per hour over a standard, round-tube bike, and plenty of energy, too, which could make the difference between a podium spot and finishing mid-pack. Swing a leg over the AR and see what it can do for you!
