Our exclusive Countervail technology has been engineered into a new aero frameset to improve power output, rider control, and aero position efficiency.
The XR4 is not just the evolution of the venerable Oltre platform, it is a revolution in aero road engineering. Rather than focusing solely on minimizing wind drag with new tubing profiles, improved cable routing, and direct-mount brakes, our engineers focused on the inherent problem with aero bikes - stability and rider control.
Engineering the vibration cancellation benefits of Countervail throughout the entire frame and fork delivers greater stability and rider control. This allows the rider to maintain a more comfortable aero position for a longer duration.
Countervail also enables a stiffer driveline - improving power output by 20 watts over the Oltre XR2. Coupled with all the aero improvements derived from computational fluid dynamics and flow visualization analysis - the Oltre XR4 is the ultimate aero road bike for the most discerning enthusiast.
