cxwrench who has worked on bikes for over 3 decades and he sees this problem quite often. It's a design flaw on STI shifters. SRAM and Campy don't do it.
This is what is known as anecdotal. I've used assorted STI shifters for near 30 years, on 8 different bikes. Never had this happen. I ride with 4-5 folks all on STI, nobody's had this problem. Doesn't make your experience invalid, just one example. But do you see constant complaints here about this ?. No. That gives us some idea of how bad a problem it is and affects whether we would recommend Shimano.
