The Factor ONE represents a shift in how modern race bikes are conceived. Elite racing has evolved: riders sit further forward, run narrower bars, shorter cranks, deeper tyre volumes, and more aerodynamic positions than ever before. The ONE was engineered around these realities from day one, not retrofitted to them. The ONE’s aerodynamic advantage has been validated in wind-tunnel testing at Guelph and SASI: >8% faster than the OSTRO VAM 2.0 ~15% faster than the Cervélo S5 (2024) >22% faster than the Specialized Tarmac SL8 Maintains aero advantage beyond 15° yaw, where competing platforms lose efficiency Stage-winning performance on its first-ever WorldTour appearance at the Critérium du Dauphiné These results establish the ONE as the fastest UCI-legal road bike Factor has ever produced and the fastest verified in the industry to date. Cockpit integration without compromise The new integrated bar system removes the stem entirely, replacing it with a selection of five sizes (110–150 mm equivalents), three high-rise options, and up to 15 mm of spacer adjustability, giving riders 35 mm of stack range without sacrificing aerodynamics or handling.See photos for cockpit setup. Low vs High Comparision Colours & Availability Available in five sizes 47, 52, 54, 56, 58, the ONE comes in four colour options: Blush, Nimbus Grey, Onyx Black, and Silverstone. A front end that changes the conversation The defining feature of the ONE is its bayonet fork and “chin” fairing system, a structure made possible by recent UCI rule changes and shaped through hundreds of CFD iterations. It controls airflow at the very start of the bike, minimising spillover drag and sustaining advantage deep into yaw where other platforms lose efficiency. Geometry for the new racing era Factor’s engineering team embraced the reality that today’s riders are pushing fit boundaries once considered extreme. By decoupling the handlebar mount from the steering axis, the ONE enables reach positions that would previously require unstable stems. A revised bottom-bracket drop restores handling balance altered by shorter cranks and modern tyre choices, keeping the bike planted at high speed.
