With its size (245x143mm) and competitive weights (Nack:169gr ; Tirox:209gr) this model is designed for triathlon and time trial. It improves comfort in all phases of pedaling thanks to the ergonomic "V SHAPE" and the new PAS channel, modified in width and depth. These features guarantee a better blood flow eliminating numbness and excessive pressure in the genital - prostatic area. The tests carried out on the track and in the wind tunnel with some of the most important professional teams in the world, confirmed an improvement in the performance of 5-8%. Foams with variable density, increased by 15% in the upper part and on the tip of the saddle, allow increasing the support surface, dissipating the pressures homogeneously, as well as guaranteeing a greater support area for the Antero-ischial area, especially in the maximum aerodynamic position.
