The Tiagra FD may be the Only one I did not try! DA, Ultrega, 105, LX, XT, XTR--all tried! Only using DA7703 brifters, but was only able to get it right after switching to DA77 Bar Ends.

Maybe I was not getting something right, but I have XTR RD's and 11-32/11-34 cassette's on four of my other rides, ALL with DA7703 brifters, and am able to get them to work--just NOT my tourer! I had been wanting to try some BE's anyway, as I got a 70's Fuji tourer with them a year ago (showroom condition!) and will be checking it out soon, so want to be used to BE's.
