2026 Factor O2 Shimano Dura-Ace Di2 Road Bike
When the Factor O2 first premiered, it quickly established its pedigree with mountaintop stage victories at the Tour de France and a second-place finish at Paris–Roubaix. The 2026 Factor O2 builds on that heritage with refined manufacturing techniques that result in a frame that is lighter, stronger, and more durable than ever before.
Constructed from Toray® and Nippon Graphite® pan-based carbon fibers, the O2 delivers an exceptional balance of stiffness, comfort, and responsiveness. The Factor O2 VAM Svelte Disc fork improves front-end control and compliance, while the tapered steerer tube enhances steering precision and contributes aerodynamic efficiency at speed.
Equipped with the flagship Shimano Dura-Ace Di2 9200 12-speed electronic groupset, this bike offers lightning-fast shifting, outstanding braking control, and race-proven reliability. Combined with the lightweight Black Inc wheelset and fully integrated cockpit, the Factor O2 is perfectly suited for climbing, endurance rides, and elite-level competition.
