The ONE-S takes Factor Bikes' iconic Twin Vane split downtube mainframe as used on the 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.
