Product information "Nago R4 Nack PAS Saddle"

The Prologo Nago R4 Nack PAS saddle was developed based on the needs of the professional teams supported by Prologo and perfected thanks to the "Pressure Map MyOwn" tests to meet the needs of all cyclists looking for maximum performance and comfort even on long rides. It has compact dimensions with a length of 245 mm and T-Shape, with a slightly forward anatomical center, to provide good freedom of movement in the saddle and maximize pedaling efficiency in all positions.

Features - Prologo Nago R4 Nack PAS Saddle

  • The base is made of long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort.
  • The saddle features 2 separate fully independent sections, made of the latest generation of variable density foams, to ensure excellent support and comfort during all phases of pedaling.
  • At the center there is Prologo's PAS system: a wide central channel and a holed base to eliminate pressure peaks even during maximum pedal thrust phases.
  • Compared to the Nago R4 PAS 137 mm, the 147 mm version has 10 mm more padding on the sides and 3 mm at the top. It is therefore suitable for cyclists who require a wider base.
  • The saddle rails are made of NACK (Nano Carbon Fiber), composed of carbon fiber, Kevlar, and aluminum filaments, designed for performance-oriented cyclists seeking maximum stiffness and lightness.

Hervorragender Rennradsattel mit einer top Verarbeitung. Der Sattel ist nicht zu weich und auch nicht zu hart. Perfekt abgestimmt und sehr leicht. Mithin der beste Rennradsattel, den ich bis dato gefahren bin. Sehr zu empfehlen!
