2026 Factor O2 Shimano Ultegra Di2 Road Bike
When the Factor O2 first debuted, it immediately proved itself at the highest level of professional cycling—claiming mountaintop stage victories at the Tour de France and a second-place finish at Paris–Roubaix. The 2026 Factor O2 Shimano Ultegra Di2 Road Bike builds upon that legacy with a lighter, stronger, and more durable frame, made possible through advanced manufacturing techniques and complete in-house quality control.
The carbon layup, using Toray® and Nippon Graphite® pan-based fibers, has been refined to deliver exceptional stiffness and power transfer while maintaining compliance for long rides. The Svelte Disc fork improves handling precision, braking control, and comfort, while the tapered steerer tube enhances steering accuracy and aerodynamic efficiency.
Paired with the Shimano Ultegra Di2 8100 12-speed electronic groupset, this bike offers fast, reliable shifting and confident braking in all conditions. Whether tackling alpine climbs, rough pavement, or endurance training miles, the Factor O2 delivers race-winning performance with everyday rideability.
