Preorder

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritized (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or dispatch to you — it often never even hits the stock room shelves!

Prelaunch

With Prelaunch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Preorders.

So, instead, you can submit your email address for the item you are interested in, and we will email you as soon as stock arrives in the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indicative purposes only and can change at any time without notice.

The dates we provide are based on information given by our suppliers. Whenever we get updated information from our suppliers we will endeavor to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for dispatch to you or collection via Click & Collect on Undetermined

Prologo Nago R4 PAS 3D 137mm Tirox Saddle in Black

Brand:Prologo

Code:4711488175703

The NAGO R4 PAS is an open, high-performance multidiskiplinary saddle designed to meet the demands of professional cyclists.

This saddle brings the latest in 3D printing technology to an already iconic performance saddle. The 3D printed lattice structure features varying zones, densities, thicknesses, and strut sizes that blend together for ultimate comfort and performance. Due to the intricacy of the layered hexagonal printing, the saddle is compliant, durable, and extremely lightweight.

This model is the PAS channel version of the NAGO R4, the evolution of the iconic NAGO saddle—a Prologo classic first introduced in 2008 and winner of a Giro d’Italia and several Monument Classics over the years. Refined through “MyOwn Pressure Map” testing, this saddle meets the needs of all riders seeking maximum performance and long-distance comfort.

The T-shape design ensures greater freedom of movement thanks to a wider seating area. Its rear-positioned anatomical center allows the cyclist to easily shift position and make full use of the saddle’s length. The semi-round ergonomic shape makes the NAGO R4 PAS ideal for riders with average pelvic rotation flexibility, while the narrow 137 mm width suits those with a moderate ischial bone spacing.

This open version of the NAGO R4 features two fully independent sections, made from latest-generation variable-density foams, to provide optimal support and comfort throughout every phase of the pedal stroke. The central PAS (Perineal Area System) channel is specifically designed to relieve pressure peaks and numbness, improving blood flow and overall comfort.

The lower outer edge of the saddle features drains that allow water to seep out and also aids in the cleaning of the seat.

The rail is available in Nack (Nano Carbon Fiber), made of carbon fiber, Kevlar, and aluminum filaments, perfect for riders seeking maximum stiffness and lightness. It is also available in Tirox (light alloy steel), offering excellent vibration absorption and a great weight-to-strength ratio. The base is made from long carbon fiber for the Nack rail, or in injected carbon fiber for the Tirox rail. These materials offer a great balance between stiffness and comfort.
