This isn't just a component; it represents a total integration of rider and machine, where pure engineering meets the highest level of aerodynamic refinement. By utilizing advanced CFD testing and wind tunnel validation, this saddle redefines the frontier of racing performance, ensuring that every watt you produce is translated into forward momentum without the drag of traditional designs.\u003c\/p\u003e\n\n\u003cp data-path-to-node=\"1\"\u003eAt the heart of its innovation is a fully integrated Nack rail, crafted from nano carbon fiber and concealed beneath sculpted lateral wings. These wings work as aero-foils, redirecting airflow and significantly reducing drag coefficients while maintaining an ultra-lightweight profile of just 152g. The reduced stack height and optimized rail-to-base connection enhance structural stiffness, providing you with the precise handling and efficient power transfer necessary for technical descents and high-speed breakaways.\u003c\/p\u003e\n\n\u003cp data-path-to-node=\"2\"\u003eBeyond its speed, the Choice PAS 140 Nack prioritizes the long-distance comfort required for elite competition. Using pressure mapping data and variable-density foam, the T-shape and semi-round profile adapt to your body throughout the entire pedal stroke. The Perineal Area System further eliminates pressure peaks and numbness by maintaining healthy blood flow. This performance is matched by a revolutionary modular design, allowing for the sustainable replacement of components via a patented two-screw system, ensuring your investment remains as durable as it is fast.\u003c\/p\u003e","brand":"Prologo","offers":[{"title":"140mm \/ Black","offer_id":54293231042906,"sku":"2028964","price":319.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Prologo-Choice-PAS-140-Nack-Saddle-Black.jpg?v=1781187670","url":"https:\/\/checkout.sigmasports.com\/products\/choice-pas-140-nack-saddle-17hjz","provider":"Sigma Sports","version":"1.0","type":"link"}
