Factor ONE Disc Dura Ace Road Bike

Revolutionary Evolution
The ONE is not a revolution pulled from thin air; it is the evolution of everything we’ve learned in recent years. From the Olympic-record-breaking HANZŌ Track to the all-conquering OSTRO VAM, each project has added layers of knowledge. We’ve amassed a deep understanding of form and shapes, fusing CFD, wind tunnel, 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 were ready. We pushed to the very edge of what is now possible, not only aerodynamically, but in rider fit and handling. In its first public appearance, unannounced, in prototype form, the ONE won a stage of the Critérium du Dauphiné. It was not a debut. It was a declaration.

Focused modern geometry
Aerodynamics was only half the mission. The modern racer’s position has shifted, using narrower bars, more forward saddles, shorter cranks, all of which pushes the rider’s weight further over the front wheel. Without carefully focused geometry, this can upset handling balance and increase crash risk. The ONE’s geometry was designed to accommodate these WorldTour positions without compromise. By decoupling the handlebar mount from the steering axis, we can give riders the extreme reach they want without resorting to unstable, overlong stems. We adjusted bottom bracket drop to compensate for the raised center of gravity from shorter cranks and larger tires, preserving stability and keeping front/rear weight balance in check. Even in the smallest sizes, the ONE keeps identical steering geometry to the largest frames, a rarity in high-performance road bikes.

Advanced use of CFD
Advances in Computational Fluid Dynamics (CFD) have made possible unprecedented insight into airflow, allowing us to iterate hundreds of virtual prototypes before ever stepping into a wind tunnel. Not only is the tool effective, but we have experience to read it and the understanding to apply it. Our development team used their years of accumulated knowledge and the lessons we’ve learned to understand and interpret the results. Every decision was tested, refined, and proven, on screen and on the road. But this isn’t just about slicing through the air. We studied the changing position of the modern racer. They are rotated forward over the front of the bike, pushing saddles further forward, using shorter cranks, narrower bars, a longer reach. The UCI has responded to these trends with new rules, and the ONE is designed to embrace them, putting the rider in their most powerful position while maintaining perfect handling balance and center of gravity.
