The Scratch M5 is a multidisciplinary saddle designed for riders who demand both comfort and high performance across varied cycling disciplines. With a compact footprint of 250 x 140 mm and a remarkably low weight of just 153 g in the Nack version, it offers a sleek, efficient platform for road cyclists, gravel riders, and cross-country or marathon MTB enthusiasts alike. Its signature T-shape and anatomical round profile provide a unisex fit that caters to a broad range of body types and riding styles.

Engineered with a wider seating platform and a rear-positioned anatomical center, the Scratch M5 encourages dynamic positioning, allowing the rider to easily adjust their posture and make full use of the saddle's length. The round design contributes additional lumbar support and improved pelvic stability, making it ideal for riders with limited pelvic mobility who still seek a secure and powerful pedaling position. Central to the Scratch M5’s comfort is Prologo’s MSS (Multi Sector System), developed in collaboration with the Politecnico di Milano. This technology employs five independent foam zones that respond intelligently to pedaling forces, optimizing both the push and pull phases. Each section works autonomously to enhance support and reduce fatigue, ensuring the saddle adapts to the natural motion of the rider's body.

Complementing the MSS is the Active Base technology, which incorporates a perforated base covered in light padding to minimize pressure peaks in the pelvic-genital area. This helps maintain circulation and relieve sensitive zones during long rides. The closed prostate channel design further improves protection in harsh weather conditions, shielding the perineal area from rain, mud, and debris without compromising breathability.

Structurally, the saddle is available with two rail options. The Nack rail uses a high-tech blend of carbon fiber, Kevlar, and aluminum filaments for maximum stiffness and ultra-lightweight performance. For those seeking an alternative, the Tirox version uses a robust injected carbon fiber base with a more traditional metal rail. Both configurations provide an excellent balance of rigidity, responsiveness, and comfort.

The Prologo Scratch M5 blends cutting-edge ergonomic science with advanced materials and engineering, resulting in a saddle that’s favored by elite professionals and serious amateurs alike. It’s a top-tier choice for cyclists looking to optimize efficiency, relieve pressure, and ride comfortably over long distances and mixed terrain.
