Good advice with one problem. 7-speed bar-ends are hard to find and command a premium price when you do. I just did a quick search on e-Bay for "7-speed shifters" and got about 60 hits but not one set of bar-end shifters. There were several sets of indexed downtube shifters and many MTB shifters but no bar-ends.
