    Prologo Nago R4 Maillot Jaune

    “NAGO R4 PAS Maillot Jaune” is the special edition of the iconic Prologo saddle made for the "Maillot Jaune" brand of the Tour de France, a collection of high-end accessories and components, dedicated to all fans of the Grande Boucle seeking style and performance.

    The saddle cover features the exclusive iridescent blue color, enhanced by the “Maillot Jaune” logo with yellow details as a tribute to the Tour de France.

    Designed based on the needs of professional teams supported by Prologo, the NAGO R4 PAS has been refined through “Pressure Map MyOwn” tests to meet the demands of all cyclists seeking maximum performance and comfort even on long rides.

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


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


    The open version NAGO R4 PAS features two completely independent separate sections, made with next-generation variable density foams to ensure excellent support and the right comfort during all pedaling phases. In the center, Prologo’s PAS system: a wide central channel and a perforated base to eliminate pressure peaks even during maximum pedaling force.


    The base is made of long fiber carbon, a material that offers an excellent compromise between stiffness and comfort.

    Different Rails for Every Type of Cyclist:

    • Rail Nack (Nano Carbon Fiber) composed of carbon fiber, kevlar, and aluminum filaments, for cyclists more focused on performance seeking maximum rigidity and lightness.
    • Rail TiroX in lightweight alloy steel, a material with an excellent balance between weight and strength, which gives the saddle less rigidity and superior vibration absorption, for those seeking greater comfort.
