Prologo Nago R4 PAS Nack 147 Saddle

The Prologo Nago R4 PAS Nack 147 Saddle is an open, high-performance saddle developed for professional riders and serious enthusiasts. Refined through Pressure Map MyOwn testing, it delivers race-level efficiency while maintaining comfort on long and demanding rides.

Evolution Of An Iconic Platform: This 147 mm wide PAS version builds on the legacy of the original Nago introduced in 2008, a platform that has claimed victories at the highest level including Grand Tours and Classics. It represents the latest evolution in performance-focused saddle design.

T-Shape Freedom & Wider Support: The T-shape design offers greater freedom of movement with a wider seating area. Its set-back anatomical center allows riders to shift positions easily along the saddle length for optimal power and control.

Semi-Round Ergonomics For Versatility: The semi-round ergonomic profile suits cyclists with medium pelvic rotation flexibility. The 147 mm width provides a stable base for riders with wider sit bone spacing, ensuring balanced weight distribution.

PAS Channel For Pressure Relief: The central PAS (Perineal Area System) channel is engineered to eliminate pressure peaks and numbness. It enhances blood flow and improves comfort during sustained aerodynamic or high-intensity efforts.

Nack Rail For Lightweight Stiffness: The Nack rail, made from Nano Carbon Fiber blended with Kevlar and aluminum filaments, delivers exceptional rigidity with minimal weight. It maximizes power transfer while keeping the saddle race-ready light.

The Prologo Nago R4 PAS Nack 147 Saddle combines open-channel comfort, precise ergonomics and elite-level performance for cyclists who push their limits.
