Factor OSTRO VAM Dura-Ace Di2

Factor OSTRO VAM Shimano Dura-Ace

The Factor OSTRO VAM Shimano Dura-Ace is a high-performance aero road bike designed for riders who demand race-ready speed, aerodynamic efficiency, and climbing capability. Developed and raced at the highest level of the sport, the OSTRO VAM combines advanced carbon construction with cutting-edge aerodynamics to deliver a sub-7 kg build with exceptional responsiveness and efficiency. Equally at home in the mountains or on fast, flat terrain, it offers a refined balance of performance and versatility.

Why the OSTRO VAM Stands Out

The OSTRO VAM delivers a rare combination of aerodynamic efficiency and ultra-lightweight performance, making it one of the few aero bikes capable of achieving a sub-7 kg build. Its race-proven design, refined geometry, and high-end components provide explosive acceleration, precise handling, and outstanding climbing ability, while maintaining speed and efficiency on the flats. A true all-round race bike, it offers a fast, responsive, and confidence-inspiring ride across any terrain.
