Budget Group Sets
I'm contemplating to put a modern budget group set on an old bike, just for fun.
Both with my many vintage bikes and my handful of modern bikes I have never had anything equipped with less than 600/ Ultegra, Chorus or Force and usually it's Dura Ace, Record or Red - but everything I have is at least 5 years old.
Now I see budget group sets like Claris, Tiagra, or even Centaur for ridiculously low prices and I wonder if they are any good - or maybe more specific, how a 10s Tiagra from today would compare to the first 10s Dura Ace from 15 years ago?
I wouldn't be surprised if in a direct comparison test the new Tiagra would come out ahead of the old Dura Ace... or am I dreaming?
