Factor One-S

Versatile Aerobike

The ONE-S was specifically designed to take the performance and aerodynamics of the the ONE, and put them into a more versatile package: the ONE-S.

Featuring a different front end, the ONE-S takes all frame of the ONE, but has the ability to use a different barstem combination. Whereas, the ONE, is built around Factor proprietary ONE Total Integration System.

Taking an unconventional approach to aerodynamics, the ONE-S carries over the frame features of the ONE. 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-S delivers an exhilarating, fast and supremely powerful ride.

Cutting Through the Wind

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-S 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 50 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.

Detailed Attention to Aerodynamics

Widestance Seat Stays

Wide stance seat stays let the air run through the frame and wheels, instead of around it, for superior aerodynamics and lateral stiffness.

Deep Airfoil Seat Tube

Deep airfoil seat tube contours and conforms to the rear wheel, nestling it away from the wind.

Optimized Tyre Size

While most aerodynamic wheels work best with 23mm tyres, we’ve engineered the ONE-S Chassis and Black Inc wheels so their sweet spot is with tyres between 25 and 28mm wide.

Other Features

Seatpost Options

Factor ONE-S is offered with Zero and Offset seatposts, with the aerodynamic profile allowing for easy Di2 battery internal installation. 1-bolt saddle clamp for easy setup, available for carbon and metal saddle rails (7×9 or 7×7 rails).

Power Drivetrain

The continuous downtube-to-chainstay structure of the ONE-S frame provides an unparalleled stiffness and power transfer with minimum energy loss and maximum drivetrain performance. The use of a wide BBright bottom bracket together with the Twin-Vane EVO downtube and tall chainstays make for a direct propulsion with every pedal stroke, while the CeramicSpeed equipped bearings keep the moving smooth and weatherproof.

Versatile Front End

With the redesigned front end, the ONE-S has the ability to be built with different barstem combinations, allowing you to build up one of the fastest aero bikes on the road with multiple handlebar options.
