Rewrite the Rules



Factor O2 VAM Custom Bike Build

Unbeknownst to most riders, light weight does not have to come at the expense of ride dynamics and quality. The O2 VAM is Sub-700 gram road rim or disc frame with class-leading integration and ride dynamics. Build your dream bike with us and choose from a broad selection of group set options, wheels and components. We’ll build your dream bike at Factor Bikes UK and invite you for a complimentary bike fit and bike test. Contact us to get started.

Redesigned Seat Tube

Using Boron on the back of the seat tube allows for additional compliance without buckling.

Widestance Seat Stays

Wide stance seat stays help with lateral stiffness in the rear triangle while keeping the seat stays thin for compliance and comfort.

Optimised Tyre Clearance

The O2 V.A.M. has a tyre clearance of up to 30mm wide (measured).

What’s Included?

A frameset from Factor is so much more than just a frame. Our quest for perfection means that our component must work in harmony with each other.

Not only this but you’ll receive a box of components to complete your build.
