With an aerodynamic Ultra High Modulus carbon fiber frame and high-quality, competition-ready components, the AR4 is engineered to minimize drag and maximize performance.  As with the entire AR family, its proprietary wind tunnel developed design offers an aerodynamic advantage of almost 2% over conventional round tube shaped bikes.  If that doesn’t seem like much, how does a free minute every hour sound?  It’s equally adept at climbing or sprinting, and Shimano Ultegra drivetrain and Felt Aero R2 wheels offer reliable performance for the long haul.
