Prologo Scratch M5 140 PAS Nack Saddle

The Prologo Scratch M5 140 PAS Nack Saddle is a cutting-edge evolution in cycling ergonomics, built with advanced 4.0 technologies for enhanced performance and versatility. Designed with the new "T SHAPE" and a compact 250 x 140 mm profile, the M5 suits both men and women across multiple riding styles. Developed in collaboration with the Politecnico of Milano, the MSS (Multi Section System) uses active foam divided into five distinct zones that adapt individually to each rider’s pedal motion—boosting comfort, absorbing vibration, and enhancing efficiency through smart support.

Engineered for maximum comfort, the M5 features a PAS (Perineal Area System) channel that improves blood flow and reduces pressure on sensitive areas, effectively preventing numbness. The saddle’s round shape adds stability and lumbar support, while its smart pressure distribution across a broader surface ensures long-lasting ride comfort. Whether you're training or racing, the Scratch M5 delivers a next-level experience in both ergonomics and performance.
