2011 Felt AR4 Road Bike
A collaborative development effort between Felt engineers and athletes, the AR was officially unveiled at the 2008 Tour de France. The competition immediately took notice. The pros know that at the speeds they race, aerodynamic efficiency matters. It can be the difference between winning and losing.
Blending the lightweight, stiff and quick-handling performance of a professional-grade carbon fiber road racing bike with the aerodynamic advantages of a time trial bike, the AR has redefined what a road bike is capable of accomplishing.
Like all Felt road bikes, the AR is characterized by crisp handling. The proprietary blend of carbon fiber materials used to construct the frame give it the stiffness and ride quality for which Felt is known.
The AR is the bike a great number of Felt’s ProTourriders use any time they put a nose in the wind. It’s the perfect machine for making a successful breakaway, or bringing one back. It has been become a critical part of the team’s stable of race bikes.
