Designed and built with no compromises, the FACTOR O2 delivers a high-performance ride capable of satisfying the demands of the fastest riders in the ProTour peloton. This is the weapon of choice of Romain Bardet and the AG2R team. To dance up the mountains, and storm down the descents.

Manufactured in FACTOR’s advanced carbon fibre facility to the highest standards, the O2 blends three different types of carbon, applied expertly to provide both high stiffness and comfort,depending where it’s needed. 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. All that in a sub-800g frame weight. This is the result of FACTOR’s expertise with carbon fibre manufacturing for over two decades.

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.

Dance Up The Mountains

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.

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.

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.

Svelte Fork

Up front, the O2 frame is complemented by the Svelte fork. Frame and fork have been designed together to work in unison with the highest performance in mind: lateral stiffness with some vertical compliance for comfort, excellent torsional stiffness for increased control while cornering and descending. All those great characteristics packed in a very light weight fork. 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 in 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, to achieve the same high performance numbers, but with a slightly asymmetric design and specific layup to withstand the disc braking forces.

Wide Stance Seatstays

This design helps with lateral stiffness in the rear triangle, while keeping the seatstays thin for vertical compliance (comfort) and light weight. On the rim brake version, the wide stance seatstays help keep brake chatter away and increase braking power.

Seatpost Options

Factor O2 is offered with Zero and 25mm offset seatposts options, both allowing for easy Di2 internal battery installation.

The forged aluminum 1-bolt saddle clamp makes saddle adjustment easy, and is available for carbon and metal saddle rails (7×9 or 7×7 rails).

Stealth Seatpost Wedge

The clean lines of the O2 frame are further accen-tuated by the stealth seatpost wedge. But for Factor this design is not only made for a clean look, it also 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.

Black Inc Seatpost And Barstem

The FACTOR O2 frameset has been designed around the Black Inc components it is supplied with. The Black Inc barstem and seatpost not only are premium level components on itself, that elevate the category of any bike in the market, but they complement the personality of the FACTOR O2 perfectly. A perfect blend of torsional stiffness and vertical compliance, these components allow the FACTOR O2 frameset to fully express itself, with excellent power transfer during sprints and climbing off the saddle, all-day riding comfort and road surface absorbtion in a featherlight and elegant package.

Barstem features:

  • Integrated, full carbon, bar and stem design?
  • Titanium hardware?Reach 80mm, Drop 125mm with compact ergonomic drop shape.
  • Compatibility with latest generation Shimano DI2 bar end junction box

Seatpost features:

  • Full carbon fiber shaft construction?
  • 1-bolt, forged aluminium saddle clamp. 7×7 and 7×9 clamp options.
  • Zero and 25mm setback options. 27.2mm diameter only.
  • Compatible with Shimano DI2 internal battery.

Developed And Tested In The Real World

Factor 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 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. Achieving 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.

Black Inc Wheelsets


Black Inc Thirty

The light-as-a-feather, bullet proof, climbing wheel with an ultra comfortable ride.

The Black Thirty is more than just a climbing wheel. It accelerates like no other wheel due to its superb rim stiffness, rim profile and perfect spoke tension.

Compared to other comparable profile wheels, the Thirty has a wider rim, which makes it far more aerodynamic. Most lightweight wheels on the market are simply not aero.  This puts the Thirty in a unique category of its own, light and aero.

With the Thirty’s shallow rim design and compliance, they are also suited to rough roads and cobble stones of races such as Paris Roubaix. The Thirty’s tough construction make it just about bullet proof on harsh roads.

These wheels use the co-developed Black Inc + CeramicSpeed hub sets, a first within the industry, where we designed the hubs specifically around the tight tolerances of the silky smooth industry standard CeramicSpeed bearings.

Black Inc Fifty


The versatile, all-rounder that is the first choice for most race conditions.

Whether you are sprinting, attacking or climbing, the Black Fifty is the go-to-wheel for most conditions. The Fifty is optimal for everything except for the steepest climbs and the windiest of days. All our professional teams choose this model when they need a wheel that can do exceptionally well on the flat stages, that is also light enough to tackle the high mountain passes.

Our proprietary wide rim profile pierces through the air making it far more aerodynamic than narrower rim profiles. Our manufacturing process ensures that the Fifty has the most amount of possible compliance while being extremely laterally rigid. The Fifty is much faster than most other brand’s deeper section rims.  This has been validated through in-house CFD optimization and confirmed in the real world through our collaboration with our pro teams and ex professional test pilots such as David Millar, Ryder Hesjedal and Baden Cooke.

With its unique rim profile, hand built with quality Sapim aero variable thickness spokes and alloy nipples, the Black Fifty is more aerodynamic, durable, comfortable and stable than any other aero wheel on the market.
