More about the Factor ONE
Factor ONE isn't just another aero machine because it's unlike anything else on the road. As a radical reinterpretation of an aero bike and a clear-eyed reassessment of what it takes to win a Grand Tour stage, the Factor ONE is the culmination of a decade‑long vision to make pure, unfiltered speed the default for professional - and amateur - road cycling. Born from a "breakaway" concept and refined through years of game-changing fluid dynamics, track‑bike research, and real‑world data, the bike delivers race‑winning performance without sacrificing comfort. Its radical geometry, integrated front‑end stiffness, and that incredible front-end let riders spearhead the sprint longer and maximise whole-stage average speeds. At the same time, the ergonomics keep them relaxed enough to stay fast over hours of challenging parcours. In short, Factor ONE is the world's fastest, most adaptable road bike – built for riders who want to break speed records and take their pursuit of performance to extraordinary levels.
“You know, an entire stage is run at 50 plus K an hour, teams sitting on the front for hundreds and hundreds of kilometres, World Championships being won in 100+ kilometre breakaways. I mean, this is a different sport than what it was five or six years ago.”
Graham Shrive, Factor's Chief Engineer
SPEED DETAILS
Aero Meets Comfort
The bold geometry of the Factor ONE may look extreme, but every line serves a purpose. By decoupling the mounting area of the bar and stem from the frame’s center axis of rotation, the bike gains 50% more handlebar stiffness over the brand's AB02 model, while allowing a limited stack increase (spacers + secondary bar) that preserves an aero profile. The result: a rider-first position that stays comfortable for long-duration efforts, translating comfort directly into speed.
Fit Without Compromise
No traditional stem means a clean, aerodynamic front end. Instead, Factor ONE uses a simple numbered “stem-equivalent” system (1–5) that maps directly to Ostro stem lengths, letting fitters dial in the exact reach without adding weight or drag. Combined with 15?mm of stock spacers and optional secondary bars (+20mm), the bike offers a ±35mm fit range while keeping the aero envelope intact.
Size-Specific Handling
Small frames (54cm and below) receive the steepest head-tube angles (up to +2.5°) to preserve front-center distance, delivering razor-sharp handling and reduced “flop” at low speeds. Larger frames (56–58cm) gain a longer wheelbase and lower bottom bracket, giving a stable, confidence-boosting feel that lets riders “sit in the bike” rather than on it. Across the range, the bike feels uniformly snappy and predictable.
