Road bike saddle Prologo Choice PAS Nack 140mm

The Prologo Choice PAS Nack 140 mm is part of a very performance-oriented approach, designed for cyclists looking for maximum efficiency gains. Its compact, streamlined design, combined with Nack's carbon, Kevlar and aluminium rails, reduces weight while improving stiffness and power transmission.

Developed using CFD simulations and wind tunnel tests, it aims for better air penetration and optimum stability at high speeds. The PAS system limits pressure on the perineal area to improve comfort on long rides, while the V-shape promotes a more forward and stable position for more efficient pedalling.

With its carbon structure and variable-density foam, it offers a precise balance between support, lightness (149g) and vibration absorption. A top-of-the-range saddle, designed for competition and demanding cyclists.
