So looking at wheels the options are for lighter standard wheel (ex. Ksyrium Elite =1535g/set) or more aero wheels that are heavier (ex. Cosmic Elite = 1900g/set). I have read that there is a speed crossover point where the aerodynamic advantage overcomes the weight difference. Anyone have a feel for what that speed is, I have heard around 20mph. I like the look of aero wheels, more aggressive looking in my opinion but I don't want to do more work just because it looks better to me.
