O2 VAM

The Factor O2 VAM is the brand's ultimate lightweight climbing road bike, with a claimed 730g frame (size 54) and complete builds dipping to a UCI-busting 6.2kg. The 2023 redesign added aero tube profiling and extra stiffness while keeping race-oriented, responsive handling. Tyre clearance runs to 32mm, with the frame aero-optimised around 28mm rubber.
