Prologo Choice PAS 140 Nack - 140mm - Black Nago

CHOICE. The first integrated road saddle. Pure engineering, without compromise. Design, materials and aerodynamics at the highest level define the new frontier of racing saddles. The Choice saddle positions itself at the forefront of a total integration process, delivering comfort and performance beyond all limits.

The Choice saddle, featuring an elegant design and minimal graphics, recalls the name of the first interchangeable model launched by Prologo in 2007. Today, this concept has been reinterpreted in a highly innovative way: Choice is in fact the first integrated road saddle designed to minimise aerodynamic drag coefficients.

The product was developed using advanced CFD simulation software and refined in the wind tunnel, ensuring unprecedented aerodynamic efficiency. Its futuristic shapes, also defined through pressure mapping tests carried out with the Pressure Map MyOwn system, are combined with a next-generation variable-density foam, delivering the perfect balance between comfort and performance at every stage of the pedal stroke.

Integration and Aerodynamics

A key feature of the Choice is its fully integrated Nack (nano carbon fibre) rail, which is concealed beneath two sculpted lateral wings that redirect airflow from the front to the rear of the saddle, reducing drag while keeping weight to a minimum. The design extends beyond the saddle itself, with the entire rider-saddle-bike system considered as one. A reduced stack height and optimised rail-to-base connection improve structural stiffness, translating to better power transfer and more confident, precise handling on technical terrain and descents.

Sustainable and Patented modularity

Another revolutionary feature of Choice is its modularity, a characteristic previously unseen in a saddle of this category. With just two screws, the rail can be separated from the carbon shell, allowing individual components to be replaced if damaged. This solution introduces a more sustainable approach without compromising quality, performance, or structural integrity.

The PAS (Perineal Area System)

A central channel is specifically designed to eliminate pressure peaks and numbness, improving blood flow.
