Thanks in advance for any hints. I found a Nishiki Seral in good condition for $75 at a thrift store last week. It is set up with some funky flat bars and old school shimano seven speed sis shifters. Has a front original Sugino triple chainring. I'm thinking of buying some Forte 9 speed brifters from Performance and upgrading the wheelset with a pair I have laying around. So the new shifters should play nice with the tiagra cassette. I'm not sure what will happen though with a nine speed chain on the original chainring. An even bigger concern is whether the original Cyclone front derailleur will play nice with the new shifters. Any help on that would be appreciated.
I'd love to be able to just use the existing wheelset, but I can't find any acceptable 3x7 brifters. Shimano makes a Tourney level set, but not for a triple.
Thanks!
