The tubeset flows outward from the headtube junction, with shapes that deliver the strength, comfort and power transfer you expect, with a sleek and refined appearance. You will recognize the now common aerodynamic approach of abbreviated, somewhat squared off rear shape of the vertical tubes, which allow air to flow and fill behind, reducing drag and adding some push forward. The design is very effective for bike stability and handling in any wind, and defeats lateral torsion for rock steady power and energy transfer. The more more rounded and curved shapes combine with the judicious use of proper carbon fiber to produce the vertical compliance and smooth ride that never feels flexy or wasteful. The aerodynamic features also include the carefully positioned and executed internal cable routing system (for both mechanical and electronic systems), and Di2 junction box mount. At first glance you may wonder how the seatpost is adjusted and fastened, but if you look under the toptube and seattube junction, you'll see the bolt access. This is one of the cleanest frame designs you will ever see and with SRAM Force eTap AXS, the omission of wires or cables simply enhances the effect.

The Factor O2 is a road race bike, and the slightly sloping geometry favors speed, handling and balance you'd associate with a premium race design. A 73 degree seat tube angle is found across the board and the overall positioning is aggressive. The 56cm is built with a 154mm headtube. A 68mm bottom bracket drop will cover you in the corners and keep the bike stable at all times. Factor builds the O2 Disc with Flat Mount disc mounts and 12/142mm Thru-Axle rear, 12/100mm TA front road dropouts for improved stiffness, disc alignment and safety. The 25mm offset Factor Black Inc carbon seatpost comes standard with the frameset. A BBright bottom bracket standard is used on the frame, and we are using the SRAM DUB version for this build.

SRAM's Force eTap AXS takes the wireless shifting system to the 12-speed drivetrain, and AXS (think "Access") allows for Bluetooth connectivity for management, set-up, and monitoring. The overall drivetrain system is lightweight, and features new 12-speed specific 2x chainring and cassette combinations. Here we use the 46-33 crankset with the 10-33 cassette, giving you impressive range and efficiency with limited overlap. The Force eTap/HRD disc brake levers are intuitive and ergonomic, while the hydraulic disc brake system has been improved at the lever and the Force HRD calipers for better power and feel. SRAM Centerline 140mm Center Lock Disc Rotors are light, resist overheating, and have rounded road edges. The use of Force AXS requires the SRAM road specific XDR freehub system for the 10T cassette. We have installed the Ceramic Speed bearing equipped Black Inc XDR freehub body on the Black Inc 30 AR Carbon Disc wheelset.

The cockpit is light, clean and effectively defeats high frequency road vibration. The 27.2mm round Black Inc seatpost is light and easy to use, while it's sibling, the Integrated Carbon bar-stem is sleek, perfectly aligned and has a great feel. A San Marco Aspide Open-Fit Saddle and Arundel Gecko Pave Handlebar Tape finish out the cockpit. For the tires we opted for the Continental Grand Prix 5000 clinchers in 700x28mm with tubes.

This exciting and impressive build is even more fun to ride, and while we can build out O2 Disc framesets to your specifications, if this 52cm is right for you, don't hesitate.
