First time here. Am thinking of upgrading my '86 Schwinn Peloton's brakes, shifters, and derailleurs with lightly used indexed Tiagras including brifters. I ride the bike so much that I really want to feel safe in traffic and see what lighter, modern components can do for it. I'll keep the original stuff and restore them to the bike if I decide to sell or hang on the wall.
Any problems with my plan that any of you can see out there or is it too much trouble? Thanks. JM
