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

  • The saddle cover has an exclusive iridescent blue coloring, embellished with the "Maillot Jaune" logo with yellow details in honor of the Tour de France.
  • The new saddle, designed based on the needs of professional teams supported by Prologo, has been refined through "Pressure Map MyOwn" testing to meet the needs of all cyclists looking for maximum performance and comfort even on long rides.
  • Compact dimensions with a length of 245 mm and a T-shape with a slightly protruding anatomical center to provide good freedom of movement on the saddle and maximize pedaling efficiency in all positions.
  • Thanks to its semi-rounded ergonomic shape, the NAGO R4 PAS saddle is ideal for cyclists with average pelvic rotation flexibility, the narrow width of only 137 mm best suits riders with a lower ischial bone width.
  • The open version of the NAGO R4 PAS, features two separate fully independent parts, made of the latest generation of variable density foams, ensuring excellent support and comfort during all phases of pedaling.
  • In the center, there is Prologo's PAS system: a wide central channel and a perforated base that eliminates pressure peaks even during phases of maximum pedaling thrust.
  • The base is made of long-fiber carbon, a material that offers an excellent compromise between rigidity and comfort.
  • TiroX rail made of light alloy steel, a material with an excellent balance between weight and strength, which gives the saddle less rigidity and excellent vibration absorption, for those seeking greater comfort.

Dimensions: 245x137 mm

Saddle weight with Tirox rail: 191 g
