The principle of the Sqaero tubeset is built on airflow around the bike a bike racing speeds. That air travels in an arc, so the leading edges of the tubes are shaped in an arc and squared at the rear. The different path and shape of airflow in various sections, such as the fork legs, downtube and seattube mean those arcs are specific to the flow and wider tires. Specific need, such as the issue of the water bottle cage mounts are taken into account. The down tube widens to greater hide the lowest downtube bottle position for race days. Crucial to the airflow from that zone back over the rear wheel is the elimination of the front derailleur in favor to the single ring Force 1 drivetrain. The end result is much cleaner air and force on the frame and past the rear tire, all proven in the wind tunnel. For comfort 3T expects you to primarily rely on larger volume tires, but the thin Aeroflex rear seatstays offer some flex at impact and work to defeat vibration up from the hub.

The 3T Fundi Team Flat Mount Disc Brake Fork has more fresh design and technology than many full frames offer. The lower left leg is offset (kinked, in 3T terminology) for the disc mount, and the flat mount itself is intelligently built for both 140 or 160mm rotor/caliper set-ups. The Syntace thru-axle system for a 12/100mm hub is aero and results in great hub/fork stiffness. The carbon lay-up of the entire design is built to manage and counter the force of hub-based disc braking. While overall the frame is reasonably vertically stiff, the extra strength of the fork legs and the tapered 1⅛” 1¼” steerer tube means the front could feel a little harsher than you's expect. Of course with a 700x28m tire at 75-80 psi you'd never know. The frame's floating rear dropout is proprietary for 3T, but also uses a bolt-in style Syntace 12/142mm thru-axle.

This complete package is built with a Shimano 11-speed R8070 Di2 dominant groupset. The 52-36 chainring combo is ideal for road speeds and climbing with the R7000 11-30 cassette. 3T opted for 160mm Ultegra disc rotors, so you can truly feather the hydraulic brakes while having all the power you'll ever need. The e-Tube Di2 system is incredibly precise and efficient, with the fastest, purest shifting available. The bike is carried by a 3T Discus 45|32 LTD Carbon thru-axle wheelset and Pirelli P-Zero Velo tires. 3T provides the cockpit kit finished off by a Selle San Marco Aspide 2 Carbon-reinforced saddle.
