After launching the first saddles with CPC technology in 2013, the patented system with three-dimensional conical nano structures that increase grip and vibration absorption, we decided to extend the 3D technology to the entire saddle, to create a new ultra-light model with an innovative multi-sector cover designed starting from the analysis of pressure tests.
The NAGO R4 PAS 3DMSS features the same ergonomic T-shape and compact dimensions (245x137 mm) as the NAGO R4, the new multidisciplinary saddle already adopted by several professionals such as Tadej Poga?ar, Mark Cavendish, Geraint Thomas, Pello Bilbao and Alberto Bettiol.
Designed from pressure test analysis:
NAGO R4 PAS 3DMSS was born from the study of the Pressure Map MyOwn tests, the proprietary system of Prologo that has allowed to scientifically analyse the areas of pressure exerted on the saddle by different professional and non-professional cyclists. The data collected has allowed to design and create an extremely light 3D saddle, with a cover composed of separate sectors able to adapt better to the different areas of pressure and guarantee maximum support and comfort during all phases of the pedal stroke.
3DMSS, Multi Sector System technology goes 3D:
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, capable of adapting optimally to the individual areas of pressure exerted and supporting the cyclist's morphology. Each sector has different complex geometric shapes, variable densities and differentiated elastic coefficients, based on the position and function:
The rear section has a high density and a high elastic coefficient, to offer greater support to the ischial bones and facilitate the traction phase of pedalling
The 3 central sections, on the other hand, have a low density and a medium elastic coefficient, to offer maximum comfort where the soft tissues rest.
The front section finally has a medium density and a low elastic coefficient to offer good support even when it is necessary to pedal at the tip of the saddle.
Comfort and performance, with a record weight for a 3D saddle:
Part of our design efforts also focused on improving a typical weak point of 3D-made saddles: their weight, which is notoriously higher than that of traditional saddles. Thanks to the data from the Pressure Map MyOwn tests, it was possible to identify the areas of the saddle where the applied pressure was lower. The sections of the cover corresponding to these areas were made with specific 3D geometric shapes, designed to limit the material used, without compromising comfort or limiting the performance of the saddle. The injected long-fibre carbon base and the Nack (Nano Carbon Fiber) rail help to further lower the overall weight, while still ensuring maximum rigidity. The result? The weight of the new NAGO R4 PAS 3DMSS is only 155 grams. The lowest weight ever, compared to all the 3D models currently on the market.
*Please note that carbon railed saddles have taller oval rails compared to standard rails and will sometimes require a dedicated seat clamp depending on the seat post clamping design and brand of the seat post.
If the seat post has a vertical (top and bottom clamp), the clamp will fit carbon rails.
Side-to-side clamping seat posts require an adapter to accommodate the longer 7x9.1mm Nack carbon rails. Most brands sell interchangeable clamps to fit carbon rails. It's always worth checking with the seat post manufacturer to confirm compatibility.
