Prologo Nago R4 Nack 137 Saddle - Hard Black

The NAGO R4 (Redesign 4) is the evolution of the iconic NAGO, the Prologo saddle born in 2008 that has already won a Giro d'Italia and many Classics over the years.

Designed from the needs of professional teams supported by Prologo, the new saddle has been perfected through "Pressure Map MyOwn" testing to meet the needs of all cyclists seeking maximum performance and comfort even for long rides.

Features of the Nago R4 Nack 137 Saddle

• 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.
• The semi-round ergonomic shape makes the NAGO R4 ideal for cyclists with average pelvic rotation flexibility, the narrow width of only 137 mm, best suit riders with lower ischial bone width.
• The NAGO R4 closed version, features 3 separate fully independent sections, made of the latest generation of variable density foams, to ensure excellent support and comfort during all phases of pedaling.
• Underneath the central section, Prologo's Active Base system: a holed base in the center, to combine the benefits of a closed saddle with a greater support surface, and the advantages of an open base.
• The base is made of long-fiber carbon, a material that offers an excellent compromise between stiffness and comfort.
• Saddle rails: Rail Nack (Nano Carbon Fiber) composed by carbon fiber, Kevlar and aluminum filaments, for more performance-oriented cyclists seeking maximum stiffness and lightness.
