Factor ONE Ultegra

The Factor ONE Ultegra Di2

The Factor ONE Shimano Ultegra Di2 makes the benchmark of aerodynamic road cycling more accessible without sacrificing the performance that has made the ONE a favourite among WorldTour professionals. Shimano's Ultegra Di2 electronic groupset delivers crisp, instant shifting with the reliability and precision you expect from Japan's finest cycling engineers, housed in Factor's iconic aero carbon frame that dominates in wind tunnels and on race courses alike.

Why the ONE Ultegra Di2 Stands Out

The Factor ONE Ultegra Di2 proves that you don't need to spend at the very top to access world-class aerodynamic performance. The ONE frame's wind-tunnel credentials are unchanged regardless of groupset — and Ultegra Di2 is a genuinely excellent drivetrain that shifts with the precision and reliability of Dura-Ace at a more attainable price. This is the fastest road bike you can buy at this price point.
