Gravel Grinding Isn't Always Easy On Your Body, That's Why Prologo Made The AGX

Introducing the Prologo Dimension AGX 143 Saddle, designed for Adventure/Gravel/Cyclocross (AGX). As the official technical partner of the Strade Bianche (Italy's most famous gravel race), Prologo wanted to create the most versatile line of saddles ever, ready to accompany and support riders in any condition and environment.

The AGX was designed with three key features: the 'V-Shape,' the Carbon Fiber Base, and the PAS cut-out channel.

V-Shape: the V-Shape allows a more advanced seat in the saddle, eliminating the pressure in the frontal perineal area and providing more support in the rear part.

Carbon Fiber Base: in combination with Prologo's shock-absorbing saddle foam, it offers elasticity and shock absorption.

PAS: the channel avoids pressure spikes and numbness by increasing blood circulation. Ergonomic design and variable density foams eliminate pressure points in the perineal area.
