Scratch M5 uses 4.0 technologies; innovative in terms of size, shape, and ergonomics to be suitable for multiple uses and disciplines.

Thanks to the new design, size, and ergonomic "T SHAPE," the Scratch M5 is unisex.

The dimensions are 250 x 140mm and the weights vary depending on the model: the version with Nack carbon weighs only 132 g, while the Tirox (light alloy steel) version weighs 201 g.

The new MSS Multi Sector System seating system, designed in collaboration with the Politecnico di Milano, helps improve comfort and performance. The active and separate foams create 5 zones that work intelligently and individually, promoting the natural pedaling movement both in the push and pull phases.

The round shape of the Scratch M5 allows a natural rotation of the pelvis, creating stability and support for the lumbar areas; it also helps distribute pressure over a larger surface.

Pedal pain-free with the drainage channel designed by Prologo. The PAS (Perineal Area System) is a channel designed to eliminate pressure peaks and numbness by improving blood flow. Its particular ergonomic shape, aided by variable density foam, eliminates contact points in the prostate-genital area. The PAS channel is optimal for users who prefer performance combined with comfort over long and medium distances.
