Nago R4 PAS Carbon Saddle

What Our Gearhead® Experts Are Saying:

"What stands out is how well this saddle mixes stiffness and comfort. The Nack rails make it incredibly light, but the PAS channel and supportive shape keep it rideable for hours."

The Nago R4 PAS Carbon Saddle is engineered for riders who want both high performance and the freedom to adjust position throughout long efforts. Its 245x137mm footprint and T-shape architecture create a versatile platform that supports multiple riding postures—ideal for road endurance, fast group rides, or mixed-terrain training. The semi-round design helps maintain pelvic stability while allowing smooth fore-aft movement to match changes in gradient or effort.

At the center, the PAS channel reduces pressure along the perineal area, supporting blood flow during extended rides. The saddle’s two independent foam sections use variable-density construction, responding differently to pedaling phases to provide stable support without excess bulk.

The carbon-focused structure elevates performance. Nack rails—built from a composite of carbon fiber, Kevlar, and aluminum filaments—deliver exceptional stiffness-to-weight efficiency, helping transfer power directly to the pedals. A long-fiber carbon base reinforces that responsiveness while keeping overall saddle weight impressively low.

For riders seeking a lightweight, adaptable, pressure-relieving platform suited to long miles across disciplines, the Nago R4 PAS Carbon Saddle offers a tuned blend of comfort, efficiency, and high-performance construction.
