Factor Ostro 2.0 CZ Dura ace DI2 Road Bike

Built to dominate every ride, the Factor OSTRO VAM Road Bike, here with premium Dura Ace spec, was created with a single, uncompromising goal: to be the lightest aero-focused bike in the professional peloton. Whether you’re powering through a sprint finish, gliding over cobbles, or conquering mountain passes, the OSTRO VAM Dura-Ace delivers the perfect balance of responsiveness, stiffness, and comfort. Every detail reflects Factor’s relentless pursuit of speed and precision – paired with Shimano's outstanding Dura Ace Di2 shifting and braking, the Ostro VAM gives you the competitive edge to ride further, faster, and with total confidence.

THE NEXT GENERATION
Harnessing aerodynamics, lightness, responsiveness, and comfort in one bike is no longer a dream. Thanks to our engineers' expert carbon fibre lay-up techniques, our commitment to premium materials, and the unique control our own factory offers, the new OSTRO VAM performs in all areas. This isn't just innovation; it's a reimagining of performance on two wheels, all designed to deliver an unmatched cycling experience.
NUMBERS DON'T LIE
Experience the new OSTRO VAM: lighter, faster, unbeatable. Now 250 grams lighter and 7 watts quicker with optimised Black Inc 48|58 wheels, it redefines responsive riding with unparalleled aerodynamic efficiency. Journey through our OSTRO VAM Launchbook as we guide you using the latest computer modelling tools to unlock aero performance gains that had been unthinkable.
MASTERS OF CARBON
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, we make the feathery and fast O2 VAM).
What’s more, the uprated stiffness level is mighty, unflinching in the face of even WorldTour watt bombs. 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 our engineers’ tireless work to iterate the carbon fibre lay-up, our investment in top-grade materials, and owning our factory, which lets us do things the hard way in pursuit of the perfect ride.
CONFIDENCE BUILT IN
We 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.
