Description
Anatomical shape
T-shape saddle that ensures greater freedom of movement thanks to a wider seating area. The set-back anatomical center allows the cyclist to easily vary position by using the entire length of the saddle. The semi-round anatomical shape of the Nago R4 PAS 3D MSS provides an excellent balance between support and freedom of movement.
Technologies
In this saddle, the Multi Sector System technology, which features five different mapped zones separate from each other on each side of the saddle, each with its own density and elasticity coefficient, is made even more effective thanks to 3D printing. The PAS – Perineal Area System is the open channel in the middle of the saddle designed to eliminate pressure peaks and numbness, improving blood flow.
Base and Rail
The long-fiber carbon base and Nack (nano carbon fiber) rail make the saddle even lighter, stiffer, and more performing. The version with an injected carbon base and Tirox (light alloy steel) rail, with an excellent weight-strength balance, gives the saddle less rigidity and superior vibration absorption.

3DMSS: Multi Sector System Becomes 3D
The covers of the two Prologo 3D saddles combine the MSS (Multi Sector System) technology with an innovative 3D printing process. This allowed the creation of five separate sectors on each side of the saddle, optimizing adaptation to the individual pressure areas and supporting the cyclist’s morphology.
Each sector features different complex geometric shapes, varying densities, and differentiated elastic coefficients, depending on its position and function:
- The rear section features high density and an elevated elastic coefficient to provide greater support to the sit bones and assist in the traction phase of pedaling.
- The central section has low density and a medium elastic coefficient to offer maximum comfort where soft tissues make contact.
- The front section presents medium density and low elastic coefficient to provide good support when pedaling at the front of the saddle.
