FACTOR O2 VAM – Lightweight Climbing Bike
The Factor O2 VAM is the lightest road bike frame, featuring fully internal cable routing, and it excels like no other when the road points up and stays there. This ultralight frame is seemingly immune to gravity when climbing, yet also carves confidently and predictably through corners when descending.
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.
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.
Applying Factor’s ethos of zero compromises, the O2 VAM is the result of the most substantial engineering breakthrough in carbon bike manufacturing in decades. Ultra high-pressure moulds allow the removal of excessive resin from our base material, making the carbon stronger, lighter and more efficient.
The O2 VAM incorporates boron within the seat-tube. This allows a reduction in weight while adding both stability and strength. The resulting structural integrity dovetails with a meticulously designed BB junction, providing instantaneous power transfer. Textreme, a ‘spread-tow’ carbon fibre, is also used as the deepest layer, a fibre that is easily shaped into complex areas, meaning it can be used more efficiently. Pitch carbon fibre is the final addition and has been used in the top tube and down tube. It is ultra-high modulus and therefore astoundingly stiff.
With WorldTour-proven handling, the geometry of the Factor O2 VAM is ready to descend as aggressively as you are, yet also deliver the comfort, stability and predictability to navigate your own multi-day mountain adventures. With consistent trail across the entire size range and progressive stack and reach, O2 Series fit is surprise-free and straightforward, regardless of size.
To meet the demands of all our riders, the O2 VAM is available in either disc and rim brake frame options. For rim brake framesets, cabling enters the frame through the front of the headtube and is routed internally routed through the frame.
For disc brakes frames, the cabling is fully integrated through the Integrated Barstem.
O2 VAM is only compatible with electronic shifting/di2 groupsets only.
Wide Stance Seat Stays
To help with lateral stiffness in the rear triangle while keeping the seat stays thin for compliance and comfort.
A meticulously designed BB junction provides instantaneous power transfer and serves as the beating heart of the O2 VAM.
Numerous lay-ups and endless hours spent perfecting the design, every element of O2’s Svelte Fork focuses on the ultimate goal of increased control, stiffness, and comfort.
