ThePrologo Nago R4 Nack saddlefeatured here atEscapais a high-performance, versatile saddle designed to meet the needs of professional cyclists. Refined through “Pressure Map MyOwn” testing, this saddle meets the needs of all cyclists seeking maximum performance and comfort, even on long rides.
The Nago R4 (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle created in 2008 that has already won a Giro d’Italia and numerous Grand Classics over the years.
Anatomical Shape
The T-shaped saddle offers greater freedom of movement thanks to a wider seating area. The rear-shifted anatomical center allows the rider to easily change positions while taking full advantage of the saddle’s entire length. Its ergonomic semicircular shape makes the NAGO R4 ideal for riders with average pelvic flexibility, while its narrow width of just 137 mm is suitable for those with moderately wide sit bones.
Technologies
The closed version of the NAGO R4 features three completely independent sections, made with state-of-the-art variable-density foams, to ensure excellent support and comfort throughout the ride. Beneath the central section lies Prologo’s Active Base system: a perforated base that combines the advantages of a closed saddle—with a larger support surface—with the benefits of an open base.
Base and Rail
The long-fiber carbon base and Nack rail (nano carbon fiber) make the saddle even lighter, stiffer, and more efficient. The version with an injected carbon base and Tirox rail (lightweight alloy steel), offering an excellent balance of weight and strength, provides the saddle with less stiffness and greater vibration absorption.
