The Fastest Light Bike

The O2 VAM is purpose-built for climbing, and it's incredibly lightweight, starting at just 6.4kg for a 54cm model with Shimano Dura-Ace Di2. Unlike most disc brake bikes, it combines this low weight with impressive aerodynamics. This is important for pro riders, who can stay close to the 6.8kg minimum weight requirement even after adding pedals, cages, transponders, and race numbers. We all want the lightest bike possible, especially when facing steep climbs. The new O2 VAM achieves this with top-quality materials, computer-optimized tube shapes for the perfect balance of stiffness and weight, and an advanced manufacturing process that led to the creation of a whole new factory.

Light, And A Whole Lot Of Aero, Too.

Why make an aero climbing bike? Because rides aren't just about climbs, and aerodynamics matter beyond the slopes. Even on steep gradients, like 8%, pros climb so fast that aerodynamics are crucial. We all want a light and aerodynamic bike, but aero shapes can add weight. The challenge for a climbing-focused bike is to save energy without extra grams. Our team nailed it. In the wind tunnel, on calm or mildly windy days, the new O2 VAM is just 5W behind the fastest aero bike, the OSTRO VAM. It slashes the gap by 50% compared to the previous version across all angles. So, your climbing bike will outperform heavier aero models from other brands.

Stiffness, Handling & Poise

The new O2 VAM matches the formidable stiffness of the OSTRO VAM and delivers an exhilarating response when you power those pedals. It'll have you attacking just for the sheer thrill of it. Plus, it shares the same handling geometry, providing exceptional stability at high speeds during descents, unwavering confidence when leaning into sharp corners, and the agility to effortlessly navigate tight turns. Because a mountain bike needs to excel on the downhill journey just as much as the climb.
