Not sure. Possibly @legrandefromage might confirm specific dates but I think STI came in early 80’s? But of course not across the board and I’m pretty sure indexed gears were around a lot earlier.Just thinking out loud, is there a natural split at the point dual pivots or sti / ergo arrived on the scene?
And then dare I say it, another when disc brakes appeared on mainstream road bikes?
Maybe as @john suggests a sub forum for post 2000 Road bikes in the Road section might work?
