This is an UCI-approved time trial rig. Most won’t race a UCI time trial ever, but as Basso sees itself competing with the big boys of racing, they felt it essential to meet the same standards that WorldTour rigs are measured by. With that starting point passed, they also needed to build this bike to be fast. So they invested time and tunnel into shaping the bike to be slippery when it came to moving through air. That meant reducing frontal area. To get there, they started with the front end. The fork has wide, aero legs. The brake is built onto the back side of the fork and comes with the bike. They next went to the head tube, which itself is shaped front-to-back to move air easily around it. Atop the fork sits the integrated bar/stem/extension combo. They first designed the stem and base bar together. The integrated unit sits below the top tube and is shaped so that the stem is flat and flows into the top tube seamlessly. The base bar is a short wing, measured 44cm outside-to-outside. The extensions sit on airfoil-shaped risers, which themselves can be used or not. the extensions are gentle ski bends, and can be slid forward and back for fit.
The rest of the bike also benefits from this same thinking. The downtube starts with a notch for the fork crown, is dropped so low that they had to shape it around the front wheel, and it retains the airfoil shape while getting wider on its travel to the bottom bracket. The Seat stays are short and shaped for aerodynamics. The seat tube works as a shroud hiding the rear wheel from the wind. The seat post is also airfoil shaped, with a sliding rail for the saddle clamp.
