Prologo Nago R4 PAS 3DMSS Tirox Saddle

Prologo Nago R4 PAS 3DMSS Tirox Saddle

The Prologo Nago R4 PAS 3DMSS saddle is created at the meeting point of innovation and performance. This lightweight model weighs just 149 g and is designed for riders seeking advanced support, comfort and cutting edge technology. It builds on Prologo’s long standing development of three dimensional structures that increase grip and improve vibration absorption.

Prologo Comfort and Performance

Using data from Pressure Map MyOwn testing, Prologo identified lower pressure zones and applied specific three dimensional geometric patterns to these areas. This approach reduces material while maintaining comfort and performance. The result is the lightest full three dimensional saddle available. The Nago R4 PAS 3DMSS shares the same compact T shape and 245 by 137 mm dimensions as the Nago R4, already used by professionals including Tadej Pogacar, Mark Cavendish, Geraint Thomas, Pello Bilbao and Alberto Bettiol.

Prologo Nago Three Dimensional Multi Sector Structure

The saddle features a multi sector structure designed to support different pressure zones. The rear section uses high density material with a high elastic coefficient to support the ischial bones and assist pedalling traction. The three central sections use lower density material with a medium elastic coefficient to maximise comfort where soft tissue is positioned. The front section uses medium density material with a low elastic coefficient to maintain support when pedalling on the saddle tip.

Prologo Scientific Development and Rail Construction

Developed directly from Pressure Map MyOwn analysis, the Nago R4 PAS 3DMSS offers a scientifically informed layout for riders of all levels. The TiroX rail uses a lightweight alloy steel blend to balance strength and low weight, with increased vibration absorption for a smoother ride.
