Climb High, Ride Far When we first premiered the Factor O2, it was ridden to mountain top stage victories at the Tour de France and second place at Paris-Roubaix. As good as that version of the O2 proved to be, this revamped O2 is even better, thanks largely to improved manufacturing techniques that allow us to make the frame lighter, stronger, and more durable. Our ability to control every aspect of the manufacturing process allows us to optimize every aspect of the frame design. Advancements like the Svelte Fork increase control, stiffness, and comfort, while the tapered steerer tube enhances steering precision and introduces aerodynamic gains.
