An emphasis on stability and speed is the goal of the i9.45/i9.65 combo. If you’re a rider who spends time in the wind, long hours on the flats or are looking for one aero wheelset to cover a wide spectrum of courses or conditions, i9.45/i9.65 is your wheelset. You will rejoice as the i9.45 in the leading position carves through the air, but remains anchored and predictable when the breeze shifts. Trailing the i9.45, your i9.65 smoothes the turbulent air, saving those precious watts - because the last thing you want is your gear getting in the way.
