Factor’s ONE goes beyond aerodynamics, pushing boundaries as the fastest aero road bike ever. Proven on paper and the wind tunnel, but most importantly, on the road. Taking an unconventional approach to aerodynamics, the ONE features the Twin Vane EVO downtube at its core, designed for aerodynamic efficiency and maximum frame stiffness. Attacking the peloton against the headwind, driving at the front of an all-out criterium or leading a fast paceline through the rolling countryside, the ONE delivers an exhilarating, fast and supremely powerful ride.

Factor has worked tirelessly on the development of the Twin Vane EVO downtube to increase aerodynamic efficiency and maximum frame stiffness. The Twin Vane EVO incorporates what we learned during the extensive aerodynamic work to design the Factor SLiCK. It’s been developed through CFD in the computer the subsequently optimized and refined in the wind tunnel. This feature on the ONE shows an expertise in design and engineering that is unique to Factor.

Twin Vane EVO Downtube
Optimized Twin Vane Evo downtube allows the air to pass through while increasing the bike stiffness at the BB and headset. When paired with our Black Inc Fifty wheels, the two work together to channel wind through the downtube in a smooth flow before the seat tube splits the flow and sends it past the rear wheel.

ONE Total Integration System
Standing for ONE Total Integration System, the OTIS gives shape to the front of the ONE. Having a fully integrated system provides increased stiffness while sprinting and enhanced precision during cornering and descending. The internal cable routing provides clean aesthetics, while also improving aerodynamics.
ONE OTIS Evo Barstem

The latest evolution of the OTIS barstem, the Evo goes a step further with an improved aerodynamic profile and features. The OTIS (ONE Total Integration System) barstem assembles directly to the top of the external fork, bringing outstanding stiffness while sprinting and precision during cornering. Full internal cable routing cleans up clutter from the front of the bike while still allowing for easy bar stack adjustment and disassembly for traveling.
Features:
- Nearly invisible to the wind, due to the proven Kamm-Tail airfoil design, unyielding to even the strongest sprint induced torque
- Smart OTIS assembly system allows for 35mm of stack adjustment by adding or taking out included spacers, all while keeping a clean look.
- Ergonomic bar shape with 125mm of drop and 80mm of reach.
- Ample knee clearance during sprints or climbing out of the saddle.
- Full internal cable routing compatible with Di2 and hydraulic hoses
- Full internal cable routing compatible with Di2 and hydraulic hoses and Di2 bar-end junction box.
- All hardware is corrosion resistant stainless
ONE Disc Fork

Taking advantage of the OTIS assembly, the ONE Disc features complete internal routing; including the hidden front brake hose, only visible where it meets the caliper at the bottom of the fork leg.
The ONE Disc fork has been shaped using Factor’s aerodynamic acumen and CFD capabilities, reducing the volume of the crown where it blends into the headtube. At the same time, the wide stance fork legs allow the air to run through to further decrease aerodynamic resistance while increasing lateral stiffness. This obsession for aerodynamics also keeps things tidy, note also the disc brake caliper is housed in a recess of the fork leg.

Brake Options
Rim brake-equipped models employ the Direct Mount standard, optimized for braking performance without vibrations. The wide stance seatstays keep the rear caliper shielded from the wind.
The ONE Disc uses Flat Mount standard, with recessed caliper hardware mounts for small aerodynamic gains and cleaner looks. The bolt-on Factor 12mm thru-axles keep the whole system tidy and away from the wind
