Prologo Scratch-M5 PAS Nack 140mm Saddle Hard Black

The Prologo Scratch-M5 PAS Nack 140mm represents the pinnacle of performance saddle engineering, proven on cycling's grandest stage. Designed to excel across diverse riding demands—whether tackling steep ascents, explosive accelerations, or grueling distance efforts—this saddle delivers the responsive support and comfort that enabled its rider to dominate the 2020 Tour de France. The hard black finish combines durability with a refined aesthetic, while the 140mm width and PAS technology provide optimal pressure distribution for sustained power output and control.

Built on proven race-winning technology, the Scratch M5 PAS delivers exceptional versatility across climbing, sprinting, and endurance efforts. This saddle integrates advanced 4.0 ergonomic innovations in sizing, contouring, and pressure management, making it equally at home on road, gravel, or triathlon disciplines. The 140mm hard black design provides the responsive support and stability demanded by competitive cyclists, whether tackling mountain passes or maintaining power through extended efforts.

The Scratch M5 PAS features an innovative T-shaped design engineered for both male and female riders, measuring 250 x 140mm with the lightweight Nack version weighing just 129g. Its Multi Sector System—developed with Politecnico di Milano—employs five independently mapped foam zones that respond dynamically to pedalling mechanics, supporting both power and recovery phases. The rounded profile promotes natural pelvic rotation while distributing pressure across a broader contact area, enhancing lumbar stability and comfort during sustained efforts.

The PAS (Perineal Area System) is a channel designed to eliminate pressure peaks and numbness, improving blood flow. Its particular ergonomic design, assisted by variable density foams, eliminates contact points in the prostatic-genital area. The PAS channel is ideal for users who prefer performance combined with comfort over long and medium distances.
