Prologo Nago R4 Nack 137 mm saddle

The NAGO R4 137 (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008 that has already won a Giro d'Italia and numerous Classics over the years. Designed from the needs of professional teams supported by Prologo, the new saddle has been perfected through "Pressure Map MyOwn" testing to meet the needs of all cyclists seeking maximum performance and comfort even for long rides.

Compact dimensions with a length of 245 mm and T-shape shape, with a slightly forward anatomical center, to provide good freedom of movement in the saddle and maximize pedaling efficiency in all positions. The semi-round ergonomic shape also makes the new NAGO R4 ideal for cyclists with average flexibility in terms of pelvic rotation.

The semi round ergonomic shape also makes the NAGO R4 ideal for cyclists with medium flexibility in terms of pelvic rotation, while the narrow width of only 137 mm fits people with not too much ischial bone width.

The closed NAGO R4, features 3 separate fully independent sections, made of the latest generation of variable density foams, to ensure excellent support and comfort during all phases of pedaling. Beneath the middle section is Prologo's Active Base system: a base perforated in the center to combine the benefits of a closed saddle with a greater support surface with the advantages of an open base.

The base is made of long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort. Rail Nack (Nano Carbon Fiber) composed of carbon fiber, Kevlar and aluminum filaments, for the more performance-oriented cyclists seeking maximum stiffness and lightness.
