Prologo Choice Integrated Road Saddle

The Prologo Choice is the first integrated road saddle. Developed with CFD simulation and refined in a wind tunnel, it is designed to minimise aerodynamic drag, with a rail completely hidden by two lateral side wings that shield frontal airflow and channel it toward the rear of the saddle.

Its semi-round T-shape was defined with pressure testing on the Pressure Map MyOwn system and combined with next-generation variable-density foam. It is also modular: just two screws separate the rail from the carbon shell, so individual components can be replaced if damaged.

Key Features

• First integrated road saddle: patented design with the rail fully shielded by lateral side wings
• Wind-tunnel-refined aerodynamics: developed with CFD simulation to reduce drag
• Nack (nano carbon fibre) rail: lightweight and responsive
• Modular construction: rail separates from the carbon shell with two screws
• Reduced stack and optimised rail-to-base connection for greater stiffness and more efficient power transfer
• Central PAS channel to relieve pressure peaks
• Variable-density foam for comfort and performance
• Two widths: 140mm and 147mm

Why Choose the Prologo Choice?

For riders on modern aero frames, Choice integrates the rail into the saddle body to cut drag while keeping the saddle light, stiff and serviceable. Its modular build lets you replace the rail or shell separately rather than the whole saddle.
