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 fiber 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.
