Van Aert
ConquersRoubaix

Paris–Roubaix doesn't forgive weak equipment. 257 km. 55 cobblestone sectors. One saddle. When Wout Van Aert crossed the Roubaix velodrome finish line in first place, the Choice had just passed the most brutal product test in professional cycling.

Developed with Team Visma | Lease a Bike, the Choice is engineered for exactly this — lightweight stiffness that transfers power cleanly, an integrated carbon rail that absorbs road shock without flex, and aerodynamics that hold up when a race-winning sprint demands every watt. It didn't just survive the cobbles. It won on them.

Engineering

Aero
by Design

The CHOICE saddle was developed using advanced CFD simulation software and refined in the wind tunnel — achieving unprecedented aerodynamic efficiency in its category.

Its futuristic shape, paired with variable-density foam and Prologo's Pressure Map MyOwn ergonomic system, allows riders to hold an aerodynamic position longer in total comfort.

  • CFD simulation software development & wind tunnel validation
  • Nack nano carbon fiber rail fully concealed inside sculpted lateral wings
  • Wing design shields frontal airflow and channels it rearward
  • Ergonomics validated with Pressure Map MyOwn pressure-mapping system
  • Variable-density foam balances comfort and performance at every pedal stroke phase

Three Breakthroughs

Engineered Without
Compromise

Aerodynamics

Developed in the wind tunnel using advanced CFD simulation, the CHOICE minimizes drag coefficients to a level never before achieved in a road saddle. Every surface, every curve, is a deliberate aerodynamic choice.

Rail Integration

The Nack (nano carbon fiber) rail is completely hidden inside two sinuous lateral side wings — a patented design that shields the frontal airflow, reduces drag, and reduces overall stack height for improved power transfer.

Modularity

A first in its category: two screws separate the Nack rail from the long-fiber carbon shell. Replace damaged components individually without replacing the entire saddle — a sustainable approach that never compromises integrity or performance.

About the Brand

Italian Precision
Since 2006

Founded in Busnago (MB), Italy, Prologo has spent more than two decades at the forefront of high-performance saddle engineering. From the very beginning, the brand has been driven by a single pursuit: the perfect relationship between rider, saddle, and machine.

Prologo pioneered the Pressure Map MyOwn system — a proprietary ergonomic mapping technology used to shape and validate every saddle they produce. The result is a product line trusted by WorldTour professionals and elite cyclists on every continent.

Following the acclaimed Predator project, CHOICE marks the next chapter — introducing true aerodynamic rail integration and first-of-its-kind modular serviceability to a category that has long awaited reinvention.
