Factor O2

All-Round Road Bike
Designed to be a climber, the O2 excels on the ascents. 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.

Built to Climb

The FACTOR O2 delivers a high-performance ride capable of satisfying the demands of the fastest riders in the ProTour peloton. This is the result of meticulous geometry design work, structural carbon fibre layup optimization (for best power transfer at minimum weight) and a careful choice of components. To dance up the mountains, and storm down the descents.

Asymmetric Oversized Downtube

The FACTOR O2 features a visibly asymmetric oversized downtube, which is the backbone of the frame and largely responsible for the highly reactive and lively nature of the bike. Using FEA software and our internal test lab bench data, we have perfected the size and profile of the downtube for every size for superior riding characteristics.

Connecting the headtube to the bottom bracket and chainstays, the asymmetric downtube carbon layup is tuned for a perfect balance of torsional and vertical stiffness.

Detailed Attention to Ride Quality

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. 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).

Dance Up the Mountains

The O2 acheives a perfect balance of stiffness, comfort and light weight, the FACTOR O2 delivers a lively and reactive ride for those pushing for the highest performance.
To dance up the mountains, and storm down the descents, the FACTOR O2 is an amazing all-rounder capable to fight in a mountain stage at the Tour de France as it is to tame the pave’ at Paris-Roubaix.

Svelte Fork

Upfront, the lightweight Svelte fork complements to O2 frame. With performance in mind, they are designed to work together to provide lateral stiffness, vertical compliance for comfort, and excellent torsional stiffness for increased control while cornering and descending.

Such a feat is the result of long hours of FEA (Finite Element Analysis) during the design phase, followed by numerous carbon layup prototypes and testing in the lab and on the road.

The Svelte fork uses a tapered steerer tube with a 1-3/8″lower bearing, with the crown integrated into the frame’s downtube for increased steering precision and aerodynamic gains.

The disc version of the Svelte fork largely follows the shape and size of the rim brake fork, but with a slightly asymmetric design and specific layup to withstand the disc braking forces.

Power Drivetrain

The continuous downtube-to-chainstay structure of the O2 frame provides an unparalleled stiffness for minimum energy loss and maximum drivetrain performance. Using bigger and wider tubes with a more continuous shape allows us to use longer sheets of carbon fiber, for a stronger and lighter structure.

At the core of the Power Drivetrain sits the BBright bottom bracket shell. We choose BBright as it offers the widest possible BB shell for a smoother and stiffer transition from the wide, asymmetric downtube to the tall chainstays. All this while being able to lay the carbon fibre sheets smoothly in this area, with high compaction, without sharp or thin shapes that increase weight and decrease structural integrity. The asymmetric (narrower on the drive-side) BBright shell also improves clearance with small chainrings and powermeters.

A section cut of the BB are reveals the enlarge structure created by the gusseted joint between the downtube, seat tube and BB shell. The asymmet-ric, tall chainstays make use of all available volume for a more continuous blend into the BB shell, for extra stiffness at a low weight, while leaving room for 28mm tyres and large chainrings.

Developed & Tested in the Real World

Factor O2 has been shaped and constructed for the best perfomance 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 frame 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.

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.”
