Nago R4 - WorldTour Special Edition

Nago R4 saddle in special edition, with the 'Big O' clearly visible on the cover and a customized graphic with the colors of the World Tour teams sponsored by Prologo to celebrate their achievements and offer top performance.

The NAGO R4 is a multidisciplinary and highly performing saddle designed for the needs of professionals. Perfected thanks to the "Pressure Map MyOwn" tests, this saddle meets the needs of all cyclists looking for maximum performance and comfort even for long rides.

The Nago R4 (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008 and already winner over the years of a Giro d’Italia and numerous Classics.

Anatomical shape

T-shape saddle that guarantees greater freedom of movement thanks to a wider seating area. The rearward anatomical center allows the cyclist to easily vary position using the entire length of the saddle. The semi-round ergonomic shape makes the NAGO R4 ideal for cyclists with average pelvic rotation flexibility, while the reduced width of only 137 mm fits people with not too wide ischial bone spacing.

Technologies

The closed version of the NAGO R4 features 3 completely independent separate sections, made with next-generation variable density foams, to ensure excellent support and the right comfort during all phases of pedaling. Under the central section, the Prologo Active Base system: a base perforated in the center, to combine the benefits of a closed saddle with a larger support surface, with the advantages of an open base.

Base and Rail

The long fiber carbon base and the Nack (nano carbon fiber) rail make the saddle even lighter, stiffer, and higher performing.  The version with injected carbon base and Tirox (light alloy steel) rail, with a great weight-resistance balance, gives the saddle less stiffness and superior vibration absorption.
