The SCRATCH M5 PAS 3DMSS is an advanced, racing-inspired multidisciplinary saddle that, thanks to innovative 3D printing, becomes even more comfortable and high-performing. Weighing just 176 grams, it’s ideal for the most demanding cyclists who value cutting-edge technology.

This new saddle enhances all the qualities of the iconic Scratch M5 PAS in a three-dimensional key, a model already used by champions such as Jonas Vingegaard, Egan Bernal, Sepp Kuss, Wout Poels, John Degenkolb, Romain Bardet, and Magnus Cort.

Anatomical Shape

The T-shape design provides greater freedom of movement thanks to a wider seating area. Its rear-positioned anatomical center allows riders to easily shift their position and use the full length of the saddle.
The round anatomical shape of the Scratch M5 PAS 3DMSS offers extra lumbar support, helping riders maintain a stable position, especially useful for those with limited pelvic mobility.

Technologies

The Multi Sector System (MSS), featuring three distinct mapped zones on each side of the saddle, each with its own density and elasticity, becomes even more effective thanks to 3D printing. The PAS (Perineal Area System) is the open central channel designed to relieve pressure peaks and numbness, improving blood circulation and overall comfort.

Base and Rails

The long-fiber carbon base and Nack rail (nano carbon fiber) make the saddle lighter, stiffer, and more efficient. The Tirox rail version, made from lightweight alloy steel, offers less stiffness and better vibration absorption, providing an excellent balance between weight and comfort.
