Overview Once you have purchased your frame set, we will contact you regarding seat post setback, handlebar sizing and bottom bracket standard. Factor Bikes, the refined performance bicycle brand, has announced the new-generation of the OSTRO VAM. Designed and developed for all-round speed, the new model has been shaped around precisely managed aerodynamic gains while offering riders an uncompromised and highly responsive racing bike. Factor’s engineers sought to find balance across weight, stiffness and aerodynamics; refusing to concede any one of these three critical components at the expense of another. The result is a modern racing bike for riders who demand pinpoint handling, immediate power transfer, comfort on unforgiving roads and low weight for optimum performance on the climbs. The new OSTRO VAM has already been proven to perform in the pro peloton by Stevie Williams, general classification winner of the 2024 Santos Tour Down Under. Beyond straight-line speed with a ‘front-to-back’ design approach Beginning with the aero-critical leading edge of the bike - primarily the fork and head tube - the engineering team captured and systematically reassessed aerodynamic gains as the design moved rearward. Each of Factor’s design concepts were CFD modelled and assessed in three ways to ensure these performance gains are passed on to the rider: independently, as a complete bike, and dynamically with rider input. Designed, tested and manufactured in-house by Factor, each design idea underwent hundreds of simulation runs throughout the development cycle before wind tunnel verification and real-world testing. Key areas of optimisation compared to the previous OSTRO VAM frame include the forks, head tube, top tube, and seat post. Factor’s rapid design iteration, analysis and optimisation process has resulted in a 70 gram reduction in drag (a seven-watt saving) compared to the previous OSTRO VAM frame, with aerodynamic benefits becoming more pronounced at five- to ten-degree yaw angles that most represent real-world riding conditions.
