The fastest light bike The new O2 VAM is the definitive aero climbing bike. We didn’t invent this category, but we did perfect it: nothing else this light is as fast, nothing this fast is as light. It’s also extremely stiff, beautifully smooth and descends with the precision, confidence and speed of a fighter pilot. It’s the ultimate choice for riders seeking full-course performance on big days in the mountains, whether you’re riding the Étape du Tour or racing the Tour de France. It’s everything you dreamed of and didn’t think possible, a unicorn among bikes.
