Factor O2 VAM Custom Color All Matt Black

Offered on consignment, this Factor O2 VAM is 90% like new and built with a full top-tier configuration, including Shimano Dura-Ace Di2 12-speed and Corima MCC EVO 47 carbon wheels.

Finished in an exclusive All Matt Black custom color, this is a collector-level build for riders seeking world-class performance with a unique aesthetic.

The O2 VAM is globally recognized as the fastest climbing bike, combining ultra-light construction, exceptional stiffness, advanced aerodynamics, and world-class descending precision — ideal for riders tackling alpine routes, gran fondos, and professional-level competition.

FEATURES

The Fastest Lightweight Climbing Bike

Weighing from just 6.4 kg for a size 54 with Dura-Ace Di2, the O2 VAM sets the benchmark for disc-brake climbing bikes.

Its ultra-high-modulus carbon construction and next-gen tube shaping deliver elite stiffness-to-weight performance.

Aero Efficiency That Defies Its Weight Class

Using truncated airfoil profiles engineered for low-yaw efficiency, the O2 VAM is only 5W slower than the OSTRO VAM in the wind tunnel — outperforming many brands’ dedicated aero bikes.

OSTRO-Level Stiffness & Handling

Shares the same handling geometry as the OSTRO VAM:

precise cornering

confident high-speed descending

exceptional stability

explosive responsiveness

Ride Comfort Through Structural Engineering

Ultra-thin toptube, external seatpost, and dropped seatstays create measurable vertical compliance without sacrificing stiffness.

CeramicSpeed T47A Bottom Bracket & SLT Headset

Premium bearings ensure improved durability, maximum efficiency, and smoother power transfer.

32 mm Tire Clearance

Allows greater comfort, control, and versatility across varied terrain.
