Our Reynolds engineers designed the Pista series (Super Deev-V) wheel to make it lighter, quicker and faster than any performance wheel on the market. Created with Reynolds proprietary advanced carbon fiber layup technology, the Pista T has a Super Deep-V 66mm rim and a symmetrical, air foil shape recognized by the National Advisory Committee for Aeronautics (NACA ) as having among the very lowest drag coefficients. This unique design permits a shorter spoke length for greater aerodynamic benefit and a smoother ride than other deep section wheels. As our Reynolds engineers like to say, the SDV66 delivers the optimal balance of rim depth for ride quality, stiffness and performance.Rim Depth: 66mm Spoke Patterns: 2024 Weight: 1660 g per set (Tubular) 1945 g per set (Clincher) Hubs: Reynolds Specific Design SPOKES Front and Rear: DT Competition
