My two cents on this subject. I thought the Suntour derailleur pulleys were the best I've ever used, even better than Bullseye or other after market pulleys--seem to last forever. I even put some of them on my Super Record (blasphemy). I also believe the late 70s, early 80s Suntour Superbe rear derailleur and indexed DuraAce 7400, 01 and 02 series rear derailleurs are not only excellent functionally, but quite clean in styling as well. I like the looks and function of Nuovo and Super Record and function of the C-Record, but not the bulky aerodynamic addition on the C-Record. To me, they need to look as good as they function and both Japanese and Campagnolo models have done that. Lou Deeter, Orlando FL
