Scratch M5 Space
The Scratch M5 SPACE is the wider and more padded version of Prologo’s iconic round-shaped multidisciplinary saddle. Thanks to its innovative technologies in terms of dimensions, shape, and ergonomics, it is a favorite among both professional cyclists and demanding amateurs seeking the ideal combination of comfort and high performance.
With its compact dimensions (250 x 147 mm) and lightweight design (173 grams in the Nack version), it is a unisex saddle, perfect for road cycling, gravel, and XC/Marathon mountain biking.
Anatomical Shape
The T-shape provides greater freedom of movement thanks to a wider seating area. The rear-positioned anatomical center allows riders to easily shift position, using the full length of the saddle. Its round shape offers extra support to the lumbar region, helping riders maintain a stable position—especially useful for those with limited pelvic mobility.
What sets the Scratch M5 SPACE apart is its wider seat and enhanced padding, providing greater comfort.
It is the perfect choice for riders with wider pelvises or those who require better weight distribution.This model features 5 mm more foam padding than the standard version.
Technologies
The MSS – Multi Sector System, developed in collaboration with the Politecnico di Milano, improves comfort and performance. The saddle features active and independent foam zones that create 5 separate sectors, working intelligently to support natural pedaling movement during 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.
