Felt AR4 Road Bike 2013

YOUTUBE:JYQOMr9n1go

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.

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.
