Visually stunning and dripping with innovative design features – to the extent that it can’t be raced in UCI events – the Factor Vis Vires is a superbike in every sense of the word. Factor’s parent company bf1 systems, is the provider of electrical, electronic and composite solutions to clients in the motorsport, automotive, aerospace, and marine industries, and the Vis Vires draws upon that extensive pool of knowledge.
The striking split downtube is said to offer both increased rigidity and greater aero efficiency, while the shallow seatstays are noticeably curved and offer vast clearance either side of the tyre. The dramatic front end, meanwhile, has a stem (with an integrated Garmin computer mount) and a fork split in two and joined only by an internal rod in a design claimed to channel airflow.
Visual appeal aside, our time with the Factor Vis Vires revealed it as an unflinchingly stiff machine: fast, accurate and wholly justifying its superbike status. The Vis Vires is available in three builds, one with Shimano Ultegra Di2 and two with Shimano Dura-Ace Di2, including this flagship £9,999 machine with Factor’s own Factor Power Measurement Crank.
