Redesigned From the Inside Out

Utilising industry-leading technology learned through the O2 VAM project, the second generation of O2 is lighter, stronger and more comfortable than before.

Pressurization greater than normal in the manufacturing process removes excess resin, making O2 carbon stronger, lighter and more efficient.

Confidence, Control and Comfort

Versatility is achieved through geometry specifically optimised for consistent handling across all sizes. Rear mechanical trail increases reflecting the higher centre of gravity of larger sized riders.


  • Tyre clearance of up to 30mm wide (measured).
  • Direct mount rim brake compatible
  • Flat mount disc brake to accommodate 140 and 160mm rotors

Technology & Engineering

Asymmetrical Downtube

This serves as the backbone of the frame connecting the headtube to the bottom bracket. O2’s asymmetrical downtube provides a perfect balance of torsional and vertical stiffness and is largely responsible for the highly reactive and lively nature of the bike.

Power Drivetrain

At the core of the Power Drivetrain sits the asymmetric bottom bracket, the design of which facilitates a smooth yet stiff transition between the asymmetric downtube and the tall chainstays. The continuous downtube-to-chainstay structure of the O2 frame provides unparalleled stiffness for minimum energy loss and maximum acceleration.

Svelte Fork

Numerous layups 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. Precise and light, the Svelte Fork uses a tapered steerer tube for increased steering precision and aerodynamic gains.


Sleek Internal Cable Routing

The internal routing for the O2 series accommodates both electronic and mechanical shifting while remaining mechanic-friendly and lightweight.


Wide Stance Seat Stays

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



Brilliantly Engineered

Applying Factor’s ethos of zero compromises, O2 is the result of the most substantial engineering breakthrough in carbon bike manufacturing in decades.

Ultra high pressure molds allow the removal of excessive resin from our base material, making the carbon strong, light and more efficient.

The shared DNA of the O2 & O2 VAM pairs years of innovative engineering, with proven performance and our obsessive pursuit of perfection.

Perfectly Balanced

With WorldTour-proven handling, the geometry of the O2 Series descends aggressively, yet still delivers the comfort, stability and predictability to navigate the third week of a Grand Tour.

With consistent trail across the entire size range and progressive stack and reach, 02 Series fit is surprise-free and straightforward, regardless of size.

Developed & Tested in the Real World

The O2 has been shaped and constructed for the best performance on the road, not just on the test lab. After long hours spent on FEA for structural analysis and perfecting the carbon fibre layup in our factory, many frames and fork samples in all sizes were made to be tested on the road by our team of test riders, as well as some of the top professional cyclists. This extended road testing provided very valuable feedback to refine and perfect the riding characteristics of the Factor O2.
