A masterful blend of speed, style and class-leading ride quality


The ONE-S takes Factor Bikes’ iconic Twin Vane split downtube mainframe as used on our premier ONE model and combines it with a pared-back Shank fork which shares the same aerodynamic lower sections as the ONE’s dual clamp OTIS fork but with a traditional, internal steerer to deliver a lighter, more compliant but still massively aerodynamic front end, together with a direct-mount dual-bolt brake interface.

Dressed with full Shimano Ultegra Di2 with an FSA cockpit, Black Inc Fifty carbon clincher wheels and rolling on CeramicSpeed bearings throughout, the ONE-S Ultegra will unleash your potential. The ONE-S blends the ONE’s exceptional aerodynamic performance with a balance of light weight, stiffness and road buzz dampening that’s unrivalled for its class.

Developed as a total system, the ONE-S has been created in collaboration with aerodynamic maestros bf1systems – one of the premier providers of wind-tunnel and downforce measurement to Ferrari, Aston Martin, Lamborghini, Maserati and multiple F1, Moto GP and WRC teams. Together, we have realised a masterful blend of speed, style and awe-inspiring ride quality in the ONE-S.

As with the ONE, the fork works symbiotically with the iconic Twin Vane split downtube to take the dirty turbulent air from the front wheel and funnel it through – rather than around – the downtube to deliver a meaningful aerodynamic advantage that will help deliver you to your goals, first. Our standard internal Shank fork allows you to fine tune bike fit for a super low or more upright cockpit set up using standard bars and stem.

Tested and developed in the fires of competition, the ONE-S – like all models in the Factor Bikes collection – has been forged by our professional team riders, former world champion track racers, and by both Baden Cooke and David Millar. The result is an insatiably addictive ride that delivers maximum speed with a class-leading ride quality so you can ride closer to the edge, more of the time.
