      Oh, another point, get friction shifters! I have NEVER had good luck
      with index shifters. which was part of the point I made in my last
      note. I love my friction shifters. yes, sometimes I have a little
      problem with the chain not quite in one gear or another, but when I
      have friction shifters, I can jiggle them to the right place. you can
      NOT do this with index shifters!
