Factor launches ONE: An insane aero bike with ‘modern geometry’, a barely-legal fork, no stem, and a head tube that could cut fruit

If 2025 will be known for anything in the bike industry, it ought to be the proliferation of mad-looking aero bikes.

Colnago’s Y1Rs, Cervelo’s S5 and Ridley’s Noah Fast 3 are all examples, but none broke the internet as much as when the Factor prototype showed up at the Dauphine.
