Nago R4 CPC

This saddle is the CPC – Connect Power Control version of the high-performance, multidisciplinary model designed to meet the demands of both professionals and highly demanding amateurs.
Refined through “MyOwn Pressure Map” testing, the NAGO R4 CPC meets the needs of cyclists seeking maximum performance, unrivaled grip, and top-level comfort, even during long rides.

Anatomical Shape

A T-shaped saddle offers increased freedom of movement, thanks to a wider seating area.
The rear-positioned anatomical center allows the rider to easily shift positions and make full use of the saddle's length.
Its semi-round ergonomic design makes the NAGO R4 CPC ideal for riders with moderate pelvic rotation flexibility, while the narrow width of just 137 mm is suitable for cyclists with a relatively narrow ischial structure.

Technologies

The CPC technology on the saddle cover, patented by Prologo for cycling use, is made of a special 3D conical polymer that significantly improves vibration absorption, grip, and positional stability.
Thanks to its nanostructure, this system reduces muscle fatigue and promotes airflow, helping to lower the temperature in the contact area.

The closed version of the NAGO R4 CPC features three fully independent sections, made from next-generation variable-density foams, to ensure excellent support and comfort throughout all phases of the ride.
Beneath the central section lies Prologo’s Active Base System: a base with a central cut-out, combining the support surface of a closed saddle with the pressure-relief benefits of an open base.

Base and Rails

The long-fiber carbon base and Nack rails (nano carbon fiber) make the saddle lighter, stiffer, and more performance-oriented.
The Tirox rail version (light alloy steel), offering an excellent weight-to-strength ratio, provides less stiffness and better vibration damping.
