The iconic Nago R4 saddle enters a new era with the integration of cutting-edge 3D printing technology. The result is the Nago R4 PAS 3DMSS—a multidisciplinary, high-performance saddle crafted for elite cyclists who demand both maximum performance and long-distance comfort, whether on the road or the trail. Weighing just 155 grams, it stands among the lightest 3D-printed saddles available, blending precision-engineered support with dynamic responsiveness.

At the heart of its performance is an anatomically refined T-shape design that provides a wide seating platform while allowing superior freedom of movement. This shape supports a rearward anatomical center, giving riders the ability to shift positions fluidly across the saddle’s entire length. The semi-round profile strikes a perfect balance between comfort and control, offering structure where it’s needed most and flexibility where riders benefit from it.

The true innovation lies in the Multi Sector System (MSS), a proprietary technology that uses 3D printing to map five distinct zones on each side of the saddle. Each zone has been engineered with its own density and elasticity, allowing the saddle to actively respond to the rider’s pedaling motion and pressure changes. This system is further enhanced by the PAS (Perineal Area System), an open central channel that relieves pressure in sensitive areas, increases blood flow, and eliminates numbness during long rides. Together, these technologies deliver a highly tailored fit and support system that adapts to the rider’s unique morphology and motion.

Structurally, the Nago R4 PAS 3D is built around a high-performance carbon fiber base that maximizes stiffness and power transfer. Paired with Nack rails—a composite of carbon fiber, Kevlar, and aluminum filaments—the saddle offers ultralight efficiency and vibration-dampening characteristics.

Measuring 245mm long and 137mm wide, this saddle offers a compact yet supportive footprint. With its groundbreaking use of 3D printing, lightweight construction, and race-proven ergonomic profile, the Nago R4 PAS 3D stands at the forefront of modern saddle design—where anatomical precision meets elite performance.
