Thanks to its new design, size and ergonomic "T SHAPE"shape, the Scratch M5 is unisex. 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. Enjoy the benefits of an open saddle and a closed one at the same time: the "'"Active Base"'" technology means that the Scratch M5 comes with a perforated but coated base to eliminate pressure peaks in the pelvic-genital area. The prostate area closure also offers better protection of the genital area in extreme weather conditions (rain or mud).
