The Prologo Dimension Space T4.0 Saddle brings a V-shape, flat anatomical profile to riders who favour a forward, aerodynamic position. Its nose sits 35mm shorter than the previous Dimension model, opening room for hip movement during hard efforts. A wide, deep Perineal Area System channel runs through the centre of the shell to ease pressure and support blood flow on long days in the saddle.
Underneath the microfiber cover, multi-density padding adds 7mm of cushioning compared to earlier versions, giving the shell a comfort-oriented feel without sacrificing support. A chromoly T4.0 rail, paired with a reinforced nylon base, keeps the structure strong while the saddle measures 245 x 153 mm and carries a claimed weight of 238 g. Standard round rails suit most seatpost clamps.
