Technologies

TIROX RAIL – The TiroX rail is made from light-alloy steel used in the aerospace industry. It offers high resistance to tension and torsion while remaining lightweight, providing a balanced combination of weight and strength under normal loads.

MSS (MULTI SECTOR SYSTEM) – The Multi Sector System was developed in collaboration with the Polytechnic University of Milan. Separate active-foam pads form independent zones that support the natural pedalling motion when pushing and pulling the pedal, and absorb vibrations transferred from the ground to the saddle.

PAS (PERINEAL AREA SYSTEM) – The Perineal Area System reduces pressure peaks and numbness in the pelvic area. The channel is formed using a special foam mould, leaving the base intact and helping the saddle retain its shape and durability over time.

SLIDE CONTROL – Developed for gravel riding, Slide Control is a functional 3D pattern on the saddle cover. It provides consistent grip and control throughout each pedalling phase, improves stability, reduces unwanted slipping and supports pedalling efficiency without restricting natural pelvic movement.
