I have a old Bianchi Limited that is a six speed double chain ring with DT friction shifters. I currently investigating what it would take to upgrade to STI type shifters.
I assume I will need more components than just the brifters. From the online shops that I've looked at brifters tend to only come in 7+ speed arrangements. So will I need a new wheel set? Rear derailer? Front derailer? Chain ring?
Thanks for any help.
