Felt Ar4 2013 Road Bike. With an aerodynamic UHC Advanced carbon fibre frame and high-quality, competition-ready components, the AR4 is engineered to minimize drag and maximize performance. Extensive wind-tunnel development has proven it capable of shaving seconds off your time. It's equally adept at climbing or sprinting, and with Shimano Ultegra drivetrain and Shimano wheels, you're guaranteed reliable performance for the long haul.
Blending the lightweight, stiff and quick-handling performance of a professional-grade carbon fibre road racing bike with the aerodynamic advantages of a time trial bike, the AR has Redefined what a road bike is capable of accomplishing. Three years ago pro racers challenged Felt to put its aerodynamic expertise toward designing a new road bike. The racers asked Felt, makers of the world's fastest time trial and track bikes (the DA and the TK1), to help them improve their performance and efficiency in the road races they compete in day in and day out. The result of this design is clear. Against its true adversary-the wind-the AR gives racers a tangible advantage. Testing sessions at the San Diego Low Speed Wind Tunnel facility have proven that, depending on speed and wind conditions, a rider can reasonably expect to save from 58 to 75 seconds over the course of an hour when compared to a bike with round frame tubes in similar conditions. Like all Felt road bikes, the AR is characterized by crisp handling. The proprietary blend of carbon fibre materials used to construct the frame give it the stiffness and ride quality for which Felt is known. Beyond the frame, each AR is outfitted with a full complement of race-ready parts. From aerodynamic wheels to flawless drivetrains and gearing that's suited to racing speeds, the AR Series is designed and built to deliver you to your best performance ever.
