This saddle is the CPC, Connect Power Control version of the NAGO R4 PAS, an open, high-performance saddle designed to meet the demands of professional cyclists. Refined through "MyOwn Pressure Map" testing, the NAGO R4 PAS CPC meets the needs of riders seeking maximum performance, unmatched grip, and superior comfort, even during long rides. This T-shaped saddle offers greater freedom of movement thanks to a wider seating area, while the rear-positioned anatomical centre allows the rider to easily shift position and use the full length of the saddle. Its semi-round ergonomic design makes the NAGO R4 PAS CPC ideal for cyclists with moderate pelvic rotation flexibility, while the narrow 137 mm width is well-suited for riders with a smaller ischial bone distance. Specifications Dimensions: 245x137mm Weight: 160g Rail: Nano Carbon Fibre Shape: T-shape with semi-round profile The CPC technology patented by Prologo for cycling use features a special 3D conical polymer that significantly improves vibration absorption, grip, and positioning stability. Thanks to its nano-structure, it also reduces muscle fatigue and aids airflow, lowering the temperature in the contact area. Two separate, fully independent sections made with the latest generation multi-density foams, offering excellent support and comfort through every phase of the ride. The PAS (Perineal Area System) central channel is specifically designed to eliminate pressure peaks and numbness, improving blood flow. Nack Rail (Nano Carbon Fibre): Crafted with carbon fibre, kevlar, and aluminium filaments, the Nack rail is tailored for performance-driven cyclists seeking maximum rigidity and lightness.
