Designed in the wind tunnel and shaped to slice through the elements, the AR1 helps you blow past all challengers. The AR1 features a UHC Advanced + TeXtreme® carbon fiber frame, Felt Vibration Reducing Aero Road flip position carbon fiber seat post, and Shimano Dura Ace and Ultegra 11-speed drivetrain. The AR1 design takes all variables into account, resulting in a light and stiff performance for any circumstance. We have all sizes in stock and they are discounted too much to believe. The original MSRP is $7999.99 but we have them on sale for $4499.99!
