Factor O2 VAM Ultegra Road Bike Whether you’re chasing Strava KOMs, taking on the Étape du Tour, or descending mountain passes at full tilt, the Factor O2 VAM Ultegra Road Bike delivers the perfect balance of weight, stiffness, aero efficiency, and handling precision. It’s the ultimate choice for cyclists who refuse to compromise. Add to the mix smooth Shimano shifting, and you have a bike that won’t hold you back as gradients hit double digits. Born to Climb – Lightness Without Limits The O2 VAM was designed from the ground up for pure climbing performance. Weighing just 6.4kg (size 54 with Dura-Ace Di2 build), it sits among the lightest disc brake bikes ever built – yet remains fully aerodynamic. Constructed using ultra-high-grade carbon fibre and a new manufacturing process developed in Factor’s own factory, the O2 VAM achieves an unrivalled stiffness-to-weight ratio. Every pedal stroke translates directly into forward motion, making long climbs feel smoother and faster than ever before. Aerodynamics That Defy Gravity Unlike traditional climbing bikes, the O2 VAM doesn’t sacrifice aero gains for lightness. Its meticulously optimised tube shapes reduce drag so effectively that, in the wind tunnel, it’s only 5 watts behind the OSTRO VAM – the fastest aero bike in the world. Across all wind angles, the O2 VAM cuts aerodynamic drag by 50% compared to its predecessor. It flies uphill and still outpaces many dedicated aero models on the flats. Unrivalled Stiffness and Handling Precision Factor’s engineers ensured the O2 VAM handles as brilliantly as it climbs. Sharing its geometry with the OSTRO VAM, this bike offers razor-sharp handling, confidence-inspiring cornering, and exceptional stability on high-speed descents. Its incredible stiffness means explosive acceleration when you stand on the pedals, while the new Black Inc 28//33 wheelset adds featherweight performance and aerodynamic balance. Combined with 32mm tyre clearance, the O2 VAM adapts perfectly to any road condition without compromising efficiency or control.
