Description
Factor ONE Dura-Ace Di2 Road Bike
The Factor ONE Dura-Ace Di2 Road Bike is built to be the fastest UCI legal road bike available, combining advanced aerodynamics, progressive fit integration and in house engineering. Every surface, junction and structural element is shaped to control airflow, maintain stability at high yaw and convert power into forward speed with exceptional efficiency. It carries the racing knowledge gained from the HANZO projects and the OSTRO VAM and applies it to the new generation of aero rules, delivering speed that has already proven itself in WorldTour competition.
Factor ONE Aero Advantage Built Into Every Detail
The Bayonet Fork and Chin Fairing manage the airflow that spills from the front tyre, guiding it cleanly along the frame to reduce turbulence. Wide fork legs create a dedicated air channel that aligns with the rider’s legs, improving flow behaviour across the entire bike. The integrated cockpit continues the directional airflow over the head tube and into the top tube, maintaining stability even in deep crosswinds.
Factor Performance Centred Geometry
Modern racing positions are fully supported. The ONE accommodates forward saddles, shorter cranks and narrower bars without compromising handling. Extended reach options and an adjustable seatpost head allow a powerful aerodynamic fit while preserving balanced weight distribution and confident cornering. Identical steering geometry across all sizes keeps the riding character consistent.
Factor ONE In House Carbon Engineering
Factor’s own factory allows rapid development and precise control over carbon layups. The frame, fork, cockpit and fairing elements are developed as a complete system, with stiffness tuned for sprint loads and responsiveness. Every element is designed to deliver efficiency, stability and racing level performance.
Factor ONE Proven Speed
Wind tunnel testing shows the ONE outperforming benchmark aero bikes across the yaw range. Race deployment confirmed these gains in real conditions with sustained high speed riding. The result is a machine that rewards aggressive riding with tangible speed.
