THE NEXT GENERATION
Harnessing aerodynamics, lightness, responsiveness and comfort in one bike is no longer a dream. Thanks to our engineers' expert carbon fiber 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 weheels, all designed to deliver an unmatched cycling experience.
ENGINEERED FOR SPEED
The goal was to create the lightest aero-oriented bike in the pro peloton. The OSTRO VAM is a bike that can be competitive on any terrain. It is ready to win sprints, conquer cobbled classics, and summit the climbs with the best.
SUPER-THIN AERO SEATPOST
The seatpost is a slender 15mm in width, capitalizing on the latest UCI rules. Its profile is the result of an intensive study of its interaction with the chaotic airflow from the rider’s legs and a tireless R&D process. First, incremental iterations were sim tested, then rapid prototypes of the best shapes were wind tunnel tested to arrive at the best performing. The thin new seatpost is made possible by relocating the Shimano Di2 battery housing inside the seat-tube and mounted from behind the bottom bracket. This has the added benefit of avoiding seatpost removal for battery access, which reduces the risk mis-adjustment leading to incorrect height, slippage or damage from over-tightening.
ULTRALIGHT SEATPOST CLAMP
The new pusher-type seatpost clamp is repositioned at the rear of the seat-tube where it distributes force over a large area to give a very secure fixation with a low torque, allowing a very lightweight clamp, a dramatic reduction in seat-tube width. This design has now moved the battery housing into the bottom bracket being more accessible and convenient.
CERAMICSPEED T47A BB
The T47 standard for threaded bottom brackets ensures a secure fit, easy maintenance, and contributes to exceptional power transfer. Fast-spinning Ceramicspeed bearings ensure ultimate efficiency.
REVISED RIDER POSITIONING
In response to analysis of customer and pro athlete position data, two key changes have been made. First, a 45cm frame has been added to the range. Second, the seat-tube angle is 0.5º steeper.
FASTER. EVER FASTER.
Everything we know about blazingly fast bikes was merely the starting point. Using the latest computer modelling tools, the new Ostro VAM unlocks aero performance gains that had been unthinkable.
Compared to the outgoing model, after 40km, the new Ostro VAM is a dot in the distance. Compared to its rivals, it’s way out of sight. We focused on refining the front of the bike, where we could influence the airflow the most. Using a Rapid Iterative Design process, we ran simulations on dozens of head tube profiles, considering every transition and surface on the frameset. The result is a true airfoil-type profile along the waterline of the frame. Further wind tunnel testing verified that the new Ostro VAM outperforms the market.
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 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.
