Part of Prologo's restyled line of versatile saddles, this superb model is equipped with 4.0 technologies which make it innovative in terms of size, shape & ergonomics. It features an ultra-tough nack rail construction which allows it to withstand all the knocks & bumps from road racing & trail riding, so you can maintain your momentum with it keeping your securely held in place. Open Base Saddle Setting the benchmark for innovation, this sleek version is kitted out with an open base. This acts in the same way a perineal channel does by eliminating pressure peaks around your pelvic area. As a result, the closure of the prostate zone also offers better protection against extreme climatic conditions such as rain or mud. This is the ultimate choice of upgrade for riders who want to enjoy the ride in all-weather conditions. Technologies: Multi Sector System: The MSS- Multi Sector System, designed in collaboration with the Politecnico of Milano, improves comfort & performance. The active foams, separated from each other, create 5 mapped zones that work individually, supporting the normal pedalling movement both during the pushing & pulling phases. The round shape of the SCRATCH M5 allows the pelvis to rotate naturally, creating stability & support for the lumbar areas; it also favours the distribution of pressure over a larger surface.
