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
Asymmetric Oversized Downtube
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
Stealth Seatpost Wedge
Dance Up the Mountains
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.
