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.
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.
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
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.
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.
At the Factor Carbon Lab our team of designers and engineers tested countless tube shape iterations in the relentless pursuit of speed, performance and aesthetic perfection.
