Dance up the mountains



Factor O2 Complete Bike

The power drivetrain provides maximum stiffness and drivetrain performance with minimum energy loss. However, limiting its capabilities to only climbing would be a crime. It can sail around corners, go for long distances, and has made appearances on the podium of the Tour de France and Paris Roubaix Every tube and section of the O2 has been engineered and developed for a ProTour level quality ride: maximum power transfer under load, but also vibration dampening to feel fresh after a 6 hour ride. The O2 does all that in style, with a slender profile that will subtly stand out in any group ride. Elegance, all-day comfort and high performance coming together.

Widstance Seat Stays

Wide stance seat stays help with lateral stiffness in the rear triangle while keeping the seat stays thin for compliance and comfort. On the rim brake version, the wide stance seatstays help keep brake chatter away and increase braking power.

Stealth Seatpost Wedge

Keeps the carbon structure free of metal inserts or the need to squeeze a split carbon seat tube in order to adjust the saddle height. A rubber gasket keeps water ingress at bay, and the wedge clamping bolt under the top tube is protected from the rain and sweat.

Seatpost Options

Factor O2 is offered with Zero and Offset seatposts, with the aerodynamic profile allowing for easy Di2 battery internal installation. 1-bolt saddle clamp for easy setup, available for carbon and metal saddle rails (7×9 or 7×7 rails).

Factor O2 Reviews

“The sweetest, quickest, most beautiful bike I have ridden. It’s not one to meander around on, it goes when you want it to and when it goes it’s quick and surprisingly forgiving over quick, long rides. What else to say other than I am in love with it!”

Toby Gavin

Factor O2 Reviews

“A fantastic handling bike, comfortable enough to ride 11 hours in Leige-Bastogne-Liege in horrendous weather, yet still feel like the top end race bike it is. Clearance for 28mm tyres on a rim brake frame is fantastic – it’s hard to fault. Very comfortable for a true race bike, position can be aggressive or a bit more relaxed if required (easy to change the set up). It’s the best handling bike I’ve ever ridden and it inspires confidence on descents and corners.”

Factor O2 Reviews

“Great frame, stiff, but with no road buzz, was expecting it to climb well but it does everything well! Bought because of build quality and design.”

Edward Atkinson

Factor O2 Reviews

“The O2 is a true wolf in sheep’s clothing. A classically styled road bike, stunning performance; stiff and responsive! Overwhelmingly happy with it! The power transfer through the bottom bracket is incredible, you can really sense the design and engineering here when you put the power down. A good experience, great customer support with friendly staff at Factor UK. The whole experience leaves you feeling you have the perfect tool for any ride, even if the legs are sometimes lacking.”

Simon Crook

Factor O2 Reviews

I can honestly say that the Factor bikes (both the O2 and the One) are hands down the best bikes I have ever owned! Amazing handling, feel and comfort). They just seem more responsive, faster, they look amazing and just feel better than anything else.”
