Felt Ar2 Ult Di2 2013 Road Bike. A culmination of years of design, wind tunnel analysis, and pro testing, the AR2 gives you every aerodynamic advantage possible. The UHC-Advanced material that's used to craft the AR2's frame is more than just a high-grade carbon fibre. It's a custom blend that is engineered to give Felt's pro riders-and you-the incredible ride quality that makes this bike so unique. Combining supreme aerodynamics and superb ride quality, the AR2 is ready to race.
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.
