The Prologo Choice Saddle combines an integrated Nack carbon rail, aerodynamic side wings and a modular carbon shell in a design developed for modern road racing. Its compact, semi-round T-shape supports an aerodynamic riding position, while variable-density foam and a central PAS channel help manage pressure and maintain comfort.
Developed using CFD simulations, wind-tunnel refinement and Pressure Map MyOwn testing, Choice features lateral wings that shield the rail and direct airflow towards the rear. A removable two-screw connection allows the rail and carbon shell to be separated, enabling individual components to be replaced when damaged.
FEATURES
- Integrated Rail Design: Nack carbon rail sits behind lateral side wings for a streamlined profile.
- Aerodynamic Development: Shaped through CFD simulations and wind-tunnel testing to reduce aerodynamic drag.
- Carbon Shell: Lightweight construction provides structural support.
- Variable-Density Foam: Padding balances support and comfort across the seating surface.
- Central PAS Channel: Helps relieve pressure peaks through the centre of the saddle.
- Semi-Round T-Shape: Compact profile designed to support an aerodynamic riding position.
- Pressure-Mapped Ergonomics: Developed using Prologo’s Pressure Map MyOwn system.
- Reduced Stack: Optimised rail-to-base connection provides a compact, stiff structure.
- Modular Construction: Two screws allow separation of the rail and shell for individual component replacement.
- Two Width Options: Available in 140 mm and 147 mm widths.
