At Escapa, we present the revolutionary Factor ONE - Shimano Ultegra 2026 Bike, the result of a deep understanding of shapes and silhouettes, fusing CFD, wind tunnel testing, and real-world knowledge. How to manipulate turbulence around a spinning wheel, how to extract more speed without sacrificing stability. When the UCI relaxed key design regulations, we pushed the limits of what is now possible—not only in terms of aerodynamics but also in terms of fit and handling for the rider. In its first public appearance—unannounced and in prototype form—the ONE won a stage of the Critérium du Dauphiné. It wasn’t just a debut. It was a statement.
Unlimited Innovation: The Story Behind the ONE
Factor’s R&D team had already traveled this path. The development of the HANZŌ Track, which broke Olympic records, showed us how airflow “spills” from the front tire and affects everything behind it. Later, an internal testing project on road bikes taught us that, by freeing ourselves from the traditional constraints of the fork, we could significantly improve performance.
The OSTRO VAM proved that aerodynamic speed could be combined with ultra-light weight and a stable, responsive ride. Those projects weren’t just products—they were reconnaissance missions. Each one revealed weaknesses in established designs and gave us the tools to overcome them.
When the UCI changed the rules, we already had the experience, the manufacturing capability, and the drive to push the boundaries further than anyone else. The ONE was not designed merely to match the speed of the OSTRO VAM, but to far surpass it. That meant not only refining existing shapes, but taking them apart and rebuilding them better.
Geometry Designed for the Modern Cyclist
Aerodynamics was only half the mission. The modern rider’s position has changed: narrower handlebars, forward-set saddles, shorter cranks… all of this shifts weight toward the front wheel. Without carefully designed geometry, this can disrupt riding balance and increase the risk of a crash.
The ONE was created to adapt to these WorldTour-style riding positions without compromise. By decoupling the handlebar mount from the headset, we offer the extreme reach riders seek without resorting to excessively long and unstable stems. We adjust the bottom bracket drop to compensate for the higher center of gravity caused by short cranks and larger tires, maintaining stability and balance between the front and rear. Even in the smallest sizes, the ONE retains the same steering geometry as larger frames—a rarity in high-performance road bikes.
Advanced Use of CFD: Aerodynamics Pushed to the Limit
Advances in Computational Fluid Dynamics (CFD) have given us unprecedented vision into airflow, allowing us to create hundreds of virtual prototypes before entering the wind tunnel. We not only have the tool but also the expertise to interpret and apply it. Our development team has drawn on years of accumulated knowledge and experience to understand and refine every result.
Every decision was tested, refined, and validated both on screen and on the road. But this isn’t just about cutting through the wind: we studied the evolution of the modern cyclist’s riding position. Today, riders lean further forward, move their saddles forward, use shorter cranks, narrower handlebars, and a longer reach. The UCI has responded with new regulations, and the ONE is designed to take advantage of them, placing the rider in their most powerful position without compromising steering balance or the center of gravity.
Bayonet Fork + Chin Fairing: Uncompromising Aerodynamics
Wind tunnel testing confirmed what our CFD simulations indicated: the Bayonet Fork + “Chin” Fairing system offers the lowest aerodynamic drag and the most stable performance across yaw angles, maintaining its advantage beyond 15°, where the competition falls short.
The ONE’s front-end design doesn’t just slice through the air—it controls where the air flows next, ensuring a cleaner flow throughout the entire bike. This architecture manages airflow from the front and maintains the aerodynamic advantage even in crosswinds.
Thanks to changes in UCI regulations, we were able to break free from the dimensional constraints of the traditional fork. We took advantage of that freedom to create a wide fork with a duct in the “chin”—a forward-extending structure that controls the overflow drag generated when the airflow separates from the front tire and the crown area.
