Prologo NAGO R4 PAS 3DMSS Saddle The Prologo NAGO R4 PAS 3DMSS saddle features the same ergonomic T-shape and compact dimensions (245x137 mm) of the NAGO R4, the new multidisciplinary saddle already adopted by several professionals such as Tadej Pogačar, Mark Cavendish, Geraint Thomas, Pello Bilbao and Alberto Bettiol. The NAGO R4 PAS 3DMSS was born from the study of MyOwn pressure mapping tests, an exclusive system from Prologo which allowed a scientific analysis of the pressure zones exerted on the saddle by various professional and amateur cyclists. The data collected made it possible to design and create an extremely lightweight 3D saddle, with coverage made up of separate sectors that can better adapt to different pressure zones and guarantee maximum support and comfort during all phases of pedaling. The cover of the new NAGO R4 PAS 3DMSS combines MSS - Multi Sector System technology with an innovative 3D printing process, which has made it possible to create five separate sectors for each side of the saddle, which can optimally adapt to the different individual pressure zones and adapt to the cyclist's body shape. Each sector has different complex geometric shapes, variable densities and differentiated elastic coefficients, depending on the position and function: the rear section, with high density and high elastic coefficient, to provide better support to the ischial bones and facilitate the traction phase of pedaling;the 3 central sections have a low density and a medium elastic coefficient, to provide maximum comfort where the soft tissues rest;the front section has a medium density and a low elastic coefficient to provide good support even when it is necessary to pedal at the end of the saddle.
