FACTOR OSTRO VAM

/ Lightweight Aero Road Bike

THE NEXT GENERATION

Thanks to Factor's engineers' expert carbon fibre lay-up techniques, commitment to premium materials, and the unique control their own factory offers, the new Ostro VAM performs in all areas - aerodynamics, lightness, responsiveness and comfort. This isn't just innovation; it's a reimagining of performance on two wheels, all designed to deliver an unmatched cycling experience.

OVERVIEW

Factor's new Ostro VAM blends outrageous speed, amazing lightness, all-day comfort and delicious handling into a bike you didn’t dare hope for. It’s the ultimate race bike. You’ve never ridden faster, nor with a bigger smile.

The new OSTRO VAM says bring it on: Tour de France sprints, solo breakaways, cobbled Classics, town centre crits and the best Sunday rides ever.

The new OSTRO VAM is a sub-7kg aero weapon, so your crit bike is also your mountainous grand fondo bike and they’re both awesome. This lightness also means that the pros can use their most aero option more of the time (and for big mountain stages with summit finishes, there's the feathery and fast O2 VAM). What’s more, the uprated stiffness level is mighty, unflinching in the face of even WorldTour watt bombs.

The Everything Bike

Aerodynamics, lightness and stiffness used to be sworn enemies, impossible to bring together. Now we have more of all three in one bike than ever and it’s thanks to Factor's engineers’ tireless work to iterate the carbon fiber lay-up, our investment in top grade materials, and owning their own factory which lets Factor do things the hard way in pursuit of the perfect ride.

INCREMENTAL RAPID GAINS

Designed, tested and manufactured in-house by Factor

The development team used advanced aerodynamics to create focused concepts, then rapidly iterated and simulated each to find the best shape combinations, resulting in 111 simulation runs. Ideas were evaluated independently, as a complete bike, and dynamically with moving parts and rider impact. 3D visualisations enabled air flow assessment in 3D space, enhancing understanding of frame elements’ interactions for deeper shape optimisation during the development cycle.

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.

Build Your OSTRO

FASTER. EVER FASTER.

The R&D process went deeper than ever before, using the latest computer modelling tools to unlock aero performance gains that had been unthinkable.

Compared to the outgoing model, after 40km it’s a dot in the distance. Compared to its rivals, it’s way out of sight. Development work focused on the front of the bike, where the airflow can be influenced the most. Using a Rapid Iterative Design process, sim tests were run on dozens of profiles, including various nose cones for the head tube.

Every detail was considered, such as the transition from the narrow, 19.5mm seat-tube to the flared seat stays – which is inspired by aerospace and the ‘root’ of a wing where it meets the fuselage – and the skinny seat stays themselves, which have a true airfoil profile along their waterline. Wind tunnel tests first verified the fastest solutions and then later proved that the new Ostro VAM clearly outperforms its rivals.

CONFIDENCE BUILT IN

Factor can measure and test many things, but not the level of confidence that a bike gives you.

It’s a feeling. Building it into a bike is where art meets science, and where our design team’s decades of engineering combine with their decades of riding. The perfectly balanced handling geometry of the new OSTRO VAM – combining cat-like agility with unflappable high-speed stability and on-rails cornering – is carried over from its predecessor, which was loved by pros, customers, and reviewers alike. Greater compliance adds to both the feeling of confidence and comfort over long rides.
