The Factor 02 VAM is a sub-700g disc frame

New chassis is up there with the lightest of the light

Factor Bikes has launched a new disc road bike frame that reportedly weighs under 700g (for an unspecified frame size), making it one of the lightest production frames of its kind.

The new O2 VAM — an abbreviation of ‘velocità ascensionale media’ (‘average ascent speed’) — is a disc road frame whose name hints at its potential climbing capabilities, thanks to what Factor is calling a manufacturing breakthrough.

How is the Factor O2 VAM so light?

Using a new method of carbon compression moulding, Factor claims it has removed a significant amount of weight from the carbon layup of the frame. It says its method of applying incredibly high levels of pressure to remove excess resin resulted in carbon layers that retained their strength while being seriously compacted.

On top of this, the brand has incorporated other stiffening materials into the layup, including TeXtreme, Nippon Graphite pitch fibre and boron fibre. The new O2 VAM frame is claimed to be both lighter and stronger than the O2, while retaining the compliance of the Vista.

In addition to the new carbon layup, the successor to the O2 also features increased tyre clearance — reportedly taking up to 30mm in width — as well as improved cable routing and integration. The geometry, which was originally developed in conjunction with WorldTour athletes, remains unchanged.

Weight-weenies will no doubt enjoy the challenge of building the lightest possible setup they can, and of course the O2 VAM comes with a Naked-UD Carbon finish.

But you don’t have to have access to ultralight components in order to benefit from the weight savings. Factor states the O2 VAM frame has been designed to work with standardised kit as well, with the weight-saving benefits coming directly from the frame itself.
