The Dimension R2 is Prologo's ergonomic high-performance saddle that is part of the top range of the Dimension family, one of the most popular on the market. A multi-disciplinary saddle with compact dimensions of 245x143mm, perfect for road and XC/ Marathon use, designed for the most demanding professionals and amateurs, always on the lookout for maximum performance and top-of-the-range components. Both the tip and the central part of the saddle now have a flatter surface, to favour an even more forward and aerodynamic riding position, allowing the saddle to be used to its full length. The design has been studied to further increase the comfort of the saddle, especially when pushing hard on the pedals.
