Scratch M5 PAS CPC is the open and Connect Power Control version of Prologo’s iconic round and T-shape multidisciplinary saddle. Thanks to its innovations in size, shape, and ergonomics, this model is loved by both professionals and demanding amateurs looking for the ideal combination of comfort and top-level performance. With its compact dimensions (250 x 140 mm) and lightweight design (146 grams in the Nack version), it is a unisex saddle, perfect for road cycling, as well as gravel and Cross-Country or Marathon mountain biking. Anatomical Shape The T-shape design provides greater freedom of movement thanks to a wider seating area.The rear-positioned anatomical center allows the rider to easily change position and take advantage of the full saddle length. The round shape of the Scratch M5 PAS CPC offers extra lumbar support, helping maintain a stable position even for cyclists with reduced pelvic mobility. Technologies The CPC technology on the saddle cover, patented by Prologo for the cycling world, features a special 3D conical polymer that provides a significant boost in vibration absorption, grip, and positional stability. Thanks to its nanostructure, this system reduces muscle fatigue and facilitates airflow, lowering the temperature in the contact area. The MSS – Multi Sector System, developed in collaboration with the Politecnico di Milano, improves both comfort and performance. Its individually active foam pads create 5 separate zones that work intelligently and independently, supporting the natural pedaling motion in both the push and pull phases. The PAS – Perineal Area System central channel is designed to eliminate pressure peaks and numbness, improving blood flow and long-ride comfort. Base and Rails The rail is available in Nack (Nano Carbon Fiber): made of carbon fiber, Kevlar, and aluminum filaments—perfect for riders seeking maximum stiffness and lightness- or in Tirox (light alloy steel): offering excellent vibration absorption and a great weight-to-strength ratio. The base is made from long carbon fiber for the Nack rail, or in injected carbon fiber for the Tirox rail. Materials offering a great balance between stiffness and comfort.
