My '75 Fuji was originally a 10-speed (2x5) with the ubiquitous SunTour 14-28 out back and Sugino Maxy 51/39 crainrings. Over the years it has turned into an 18-spd (3x6). The crankset now is a Sakae SX 48/38/28 and it now wears a 13-26 6-spd Suntour Winner Ultra freewheel (just took off the 13-21 Ultra). Derailleurs are currently SunTour Compe-V front and a long cage MD(?) MTB rear (bought when my VGT-Luxe ate a pulley several years ago)... Never had a problem shifting at all. No really steep hills around here so the 28/26 is kinda overkill, but I want to try some loaded touring in the OH/PA/WV region.
