Factor ONE: The World's Fastest Road Bike
The Factor ONE is not a revolution pulled from thin air; it is the evolution of everything we've learned—from the Olympic-record-breaking HANZŌ Track to the all-conquering OSTRO VAM. The ONE is the sum of every lesson, limit, and risk we’ve taken to make speed tangible. We set out to create the fastest racing bike in the world, and have succeeded in finding new horizons of performance.
Extreme Aerodynamics
The ONE features a revolutionary Bayonet Fork + “Chin” Fairing system proven in wind tunnel testing to produce the lowest drag and most stable yaw performance. The front-end design controls airflow and sustains an aerodynamic advantage deep into crosswind yaw. This system manages the “spillover” drag created when airflow detaches from the front tire and crown area, dictating where the air goes next for smoother flow across the entire system.
Focused Modern Geometry
The geometry of the ONE is designed to accommodate the modern racer’s position—including narrower bars, more forward saddles, and shorter cranks—without compromising handling balance or increasing crash risk.
Handling: The ONE’s geometry preserves stability and keeps the front/rear weight balance in check, even with larger tires. It maintains identical steering geometry in the smallest sizes compared to the largest frames.
Cockpit Redefined: The integrated bar system removes the traditional stem, offering a clean setup. Handlebar options include the standard Low Bar for an aggressive position and the High Bar (with a 20mm rise) for a more moderate hand position. Up to 15 mm of spacers can be added, providing a 35 mm shifter stack height range.
