O2 VAM Frameset

Factor O2 VAM Frameset

The Factor O2 VAM Frameset has been engineered to deliver exceptional lightweight performance on rolling terrain, minimising weight for challenging steep uphill pitches, and yet aerodynamically efficient to fly on the downhills and power along valley floor roads. 

Born to Climb – Lightness Without Limits

The O2 VAM Frameset was designed from the ground up for pure climbing performance. It sits among the lightest disc brake framesets 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 bike frames, 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 frameset 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. Combined with 32mm tyre clearance, the O2 VAM adapts perfectly to any road condition without compromising efficiency or control.
