Nago R4 3D PAS Carbon Saddle

What Our Gearhead® Experts Are Saying:

"I like this saddle for riders who want race-level efficiency without sacrificing comfort. The 3D-printed padding really helps smooth out vibrations and pressure on longer rides, and the PAS channel keeps things comfortable when you're putting down big efforts. It’s light, supportive, and works well whether you’re riding road, gravel, or fast XC trails."

When we’re pushing the pace on long road rides or mixing in fast gravel miles, the Nago R4 3D PAS Carbon Saddle delivers the balance of comfort, efficiency, and freedom of movement we need to stay focused on the ride. Prologo evolved its iconic Nago design with advanced 3D-printing technology, creating a lightweight saddle that adapts to the rider while maintaining the responsiveness performance cyclists demand.

The 3D-printed Multi Sector System divides the saddle surface into mapped zones with varying densities and elasticity, allowing it to support our sit bones while adapting to shifting positions during long rides. This structure improves vibration absorption and pressure distribution without adding bulk. The PAS central channel further reduces pressure on soft tissue, improving comfort and blood flow during sustained efforts.

A long-fiber carbon base paired with lightweight Nack or Tirox rails ensures efficient power transfer and durability. The T-shape profile and semi-round curvature provide a stable platform while still allowing us to move naturally along the saddle during climbs, sprints, and technical terrain. With its race-ready weight and adaptable comfort, the Nago R4 3D PAS Carbon Saddle is built for riders who expect performance across road, gravel, and off-road disciplines.
