The Reynolds AR X series delivers an unmatched selection of carbon fiber wheels to offer you the perfect product capable of tracking the types of terrain and roads you ride. The AR X line of wheels carries on the heritage of our wildly popular Attack, Assault and Strike wheels with wider rim profiles optimized for modern, wider tubeless tires. Working with the wider profiles allowed our engineers to design sleek, new rim shapes that vastly improve stability in crosswinds in the deeper sectioned rims. The new AR X profiles are not only wider and faster, but they are also lighter than their Attack, Assault and Strike predecessors.
