Factor Bikes ONE-S Disc Rolling Chassis

The ONE-S was specifically designed to take the performance and aerodynamics of the ONE and put them into a more versatile package. The ONE-S uses the same advanced frame as the ONE but features a traditional fork design that enables the use of different barstem combinations.

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.

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

Factor Bikes sells system-integrated chassis, comprised of frame, fork, barstem, seatpost, bottom bracket, headset and a “pizza box” of components and accessories. Why a chassis? To control all the touch points a rider has with the road to ensure our world-renowned Factor ride quality.
