The new MSS- Multi Sector System seating system, designed in collaboration with the Milan Polytechnic, contributes to improved comfort and performance. The active and separated foams create 5 zones that work in an intelligent and individual way favouring the normal pedalling movement both during pushing and pulling.

The rounded shape of the Scratch M5 allows the pelvis to rotate naturally, creating stability and support for the lumbar region; it also favours the distribution of pressure over a larger surface area.

Pedal without pain with Prologo's patented cut out: PAS System. This channel is designed around the body shape to avoid pressure peaks and numbness in the perineal area, allowing you to pedal for many hours without discomfort or loss of power.
