Integrated Cable System
Updated and redefined for 2020, the O2 VAM now features fully internal cabling. Factor’s engineering team have created an innovative ultralight internal cable routing system that maintains the frame’s low-profile headtube, stiffness goals and tyre clearance, and even lowers the weight of the complete system. It’s win-win.
Our complete integration system uses a D-shaped steerer tube, which is reinforced for impact strength and acts as a guide for hoses. A custom headset compression plug has been specifically designed to function like a standard plug, meaning it can be easily trimmed, maintained and adjusted.
Highest Stiffness-To-Weight
Low weight doesn’t have to come at the expense of ride dynamics and quality. Despite its status as Factor’s lightest production bike, the O2 VAM remains stiff and responsive under power, shattering the glass ceiling that has for too long been imposed upon ultralight performance frames.
Instead of relying upon a collection of temperamental and difficult to obtain ultralight components to hit target weights, we challenged ourselves to deliver weight savings within the chassis. The goal? To allow the O2 VAM to be assembled into an ultralight bike with standard components, so its rider can enjoy the thrill of a featherweight bike with the reliability and compatibility of standardised kit.
What we have achieved with the O2 VAM is a frame including all assembly parts with a weight of 677g unpainted (size 54, disc). Three paint finishes are available which vary between 20-45g in weight.
Carefully Considered Integration
The O2 VAM uses a standard size (1-⅛) upper headset bearing system to maintain the aesthetic beauty of the frame and retain the aero benefits over using a wider bearing. Unlike many manufacturers, the bearing width and headtube are not increased to facilitate an internal system. The end result is a beautifully integrated O2 VAM that retains its elegant silhouette and improves aerodynamics by hiding the cables.
