Prologo Nago R4 PAS

The T-shape design is shorter than traditional saddles, which helps reduce friction on the inner thighs and allows for more aggressive, forward-leaning positions without restriction. It is particularly helpful if you find yourself shifting around frequently to find comfort during long efforts.

Yes, it is designed specifically for road cycling. The combination of the pressure relief channel and variable density foam padding is engineered to reduce numbness and support your sit bones during long hours in the saddle.

The carbon fiber rails significantly reduce the overall weight of the saddle while maintaining high stiffness. This rigidity ensures efficient power transfer, though it is worth noting that carbon rails require a seatpost clamp compatible with oval-shaped rail profiles.

A semi-round profile offers a middle ground, providing enough support for riders who move slightly in the saddle while still offering a stable platform for those who prefer a locked-in feel. It is generally the most versatile shape for a wide range of rider flexibility.

The PAS (Perineal Area System) cutout is designed to alleviate pressure on the perineal artery and nerves, which is the primary cause of numbness during rides. If you typically experience discomfort in that specific area, this channel is a highly effective solution.
