There was a sweet spot where there was. My road bike frame is from the 80s or 90s. It was built for downtube shifting, but now it has brifters. It has mixed shimano group parts from a maybe 2 decade span of time. Quill adapter to use modern handlebars made over the last 2 decades. Pretty standardized 8 speed stuff.
