Felt has been hard at work using computation fluid dynamics and wind-tunnel research to aerodynamically optimize the AR range. The AR5 provides the same aero gains, but at a lower price point. The focus isn’t just on speed though – the UHC Performance carbon frame and seatpost defeat road vibrations and deliver a comfy ride, which is challenging to achieve on an aero bike. The braking and shifting meet the standard with Shimano’s 11-speed 105 groupset. The SRP is $3,299.
