The SMR3 Pro features TiNox rails and a carbon fiber shell for decreased weight. Developed with two-time Marathon World Champion, Alban Lakata, the SMR3 is used by the Topeak-Ergon Racing team for marathon and endurance racing. It features a tuned shell with increased flex, all the while still offering great stability. This translates to more freedom of movement for the thighs while pedaling. The saddle shell geometry and contours have been optimized to work with the rider. Innovative padding comes from the latest AirCell technology with micro air pockets for increased rebound, support, and damping. The nose of the saddle is treated with silicone for extra glide and ease of movement around the saddle.
