Factor ONE Frame 58cm with Size 3 Tall Barstem and the 30mm offset post

The ONE is the fastest road bike in the world, the product of ambition, mastery,
and the refusal to settle for safe design.
For Rob Gitelis, Factor’s founder, the mission has always been clear: build the boldest and most
exciting bikes in cycling. For Graham Shrive, one of the world’s leading bicycle engineers, the
mission is to find speed everywhere it hides: in airflow, in geometry, in manufacturing, and
bring it to life on the road. Together, they’ve created a culture where innovation is not a
project, but a habit.
With our own factory and agile manufacturing capabilities, we can design, prototype, test,
and refine at a pace few can match. That freedom has made Factor a brand where racing DNA
drives engineering, and where every bike is forged in the same conditions
it will face in the world’s toughest races.
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 boundary-pushing
HANZŌ Road internal test project, to the all-conquering OSTRO VAM, each project has added layers
of knowledge: what shapes work in real-world wind, how to control 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. Advances in
Computational Fluid Dynamics (CFD) gave us unprecedented insight into airflow, letting us iterate
hundreds of virtual prototypes before ever stepping into a wind tunnel. Every decision was
tested, refined, and proven, on screen and on the road.
But this isn’t just about cutting through the air. We studied the changing position of the
modern racer: rotated forward over the front of the bike, saddles pushed further forward,
shorter cranks, narrower bars, 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 centre of gravity.
In its first public appearance, unannounced, in prototype form, the ONE won a stage
of the Critérium du Dauphiné. This was not a debut. It was a declaration.
