I have a 6 bicycles, 1 six speed with downtube shifters, 2 nine-speed, one 10 speed and two 11 speed, and I have tracked my performance for years, and my experience is that there is no measurable performance increase that can be attributed to the bicyle or the components, with the possible exception of moving from downtube shifting to brifters... But it is always fun to buy new stuff...
