The Factor ONE and ONE Disc have always represented pinnacle of the UK-based company's dedication to innovation, integration, and pure carbon construction capabilities. With the ONE-S Disc Frameset, Factor carries about 85% of the same design forward, but moves to a more standard fork, headtube, cockpit set-up. That's right, instead of the OTIS (ONE Total Integration System) front end, you can choose your ONE-S cockpit set-up and have easier adjustment, service, and flexibility. Now, do you sacrifice some of the ONE and OTIS enabled incredible aerodynamic profile and shape- yes. That is the trade-off, but in deciding to offer the ONE-S, the goal was to get more cyclists on the ONE concept, with it's Twin Vane Evo downtube and other sleek, aero forms and transitions. So, the trade-off has benefits in both directions. Factor re-engineered the front of the bike so you don't sacrifice much overall fork and junction stiffness, while reducing the weight of the assembly.

Each ONE-S Disc is built with Factor's EM2 RBi carbon system, employs various amounts of three carbon fiber types: Standard Modulus, Medium Modulus, and the costly and difficult to work with High Modulus Pitch Fiber. Each is applied to it's greatest effect, in accordance with the desired properties of each frame section or tube. Due to the challenges and costs, Pitch fiber is rarely used except at the top-end of the bike world. Factor knows the process and material well, and uses Pitch fiber to it's greatest effect. That exacting process, zero waste, highly informed engineering, and optimal materials combine to deliver a lightweight, compliant, yet super responsive frameset.

Profiting from all the aerodynamic work to design the Factor SLiCK (time-trial/triathlon machine), Factor’s R&D team has translated that tube-shaping knowledge to road bike platform. Using the sponsored pro approved geometry from the O2, the ONE-S Disc has a balanced feel with quick responsive steering and impeccable manners while descending and cornering. Other than the clean, smart lines, the most distinctive feature of the ONE series is the the development of the Twin Vane Evo downtube. This incredible design delivers more aerodynamic efficiency and maximum frame stiffness. The Twin Vane Evo takes all the engineers have learned during extensive aerodynamic work and has been iterated through repeated CFD analysis in the computer, and later optimized in the wind tunnel. This feature on the ONE Disc shows an expertise in design and engineering that is unique to Factor and leads to a truly singular ride experience that has to be ridden to appreciate.... Read More
