Has anyone been able to figure out if switching to gp5000s from their previous tires added any speed? I have gone fast with my gp5000s, faster than with any previous tire I was using, but since at the same time I also switched to an aero type of rim I can not say what the rims contributed and what the tires contributed to the extra four to six tenths of a mph I found. I am going to put my old rims back on the bike with the gp5000s just to try that combo, and maybe try the aero rims with my previous tires too, just for some fun.
