The Chrono is actually the two-year development byproduct of the production of the company’s track frame, the Pista, which Avanti developed for the New Zealand national track team.
Avanti has done its due diligence, doing FEA, CFD and wind tunnel testing—both modeling and comparative testing—at both the San Diego Low Speed Wind Tunnel and the A2 Wind Tunnel in Mooresville, North Carolina, and benchmark testing.
The frame is fully UCI approved, and will see service next year with the Pure Black pro team.
The bike features an integrated stem that is set flush with the top tube, and height adjust is manipulated through the pad stack risers of the PRO Aerobars. The bike specified with Shimano’s Di2 electronic group is clean as can be, with all cable being ported from the aerobar into the frame through the stem, with the Di2 adjustment toggle buttons fixed into an open port at the top center of the stem… very clean in look and function.
Turning the bar slightly, you can see the cables as they port into the front of the frame. And that’s it; there are zero cables exposed on this Di2 bike.
The front brakes are integrated within the front fork, and all operations for cable run move through a slightly wide bayonette nose cone. Interestingly, the front fork blades have a bit of s-bend design, staying close to the wheel and tire quite a way down the fork blade before swaying out to meet flange width for the front dropouts.
There’s a bit of unique design in the rear chainstays as well; a result of their testing resulted in stays of differing heights. Torque testing resulted in a right (driveside) stay height of 57mm (compared to 51mm for the non-driveside stay) to increase strength and stiffness. Seat adjust is set at center at 76 degrees, with several centimeters of fore/aft fit range.
