A number of changes to the 1981 Fuji S12S - replaced the Sugino XD 600 crankset with a more appropriately vintage Sugino Super Maxy 34/48T double. Apparently these TA Pro Vis clones are not all that common. I also went from Campagnolo 10 speed Ergo shifters to Suntour Power Shifters and along with those decided to go to an 8 speed 11 - 34T cassette from 9 speed, eliminating the ShiftMate pulley arrangement. I decided that an earlier Shimano rear derailleur was more appropriate than the M960 I was using, looks much nicer and shifting is quite good, the Suntour ratchet shifter design makes it almost a breeze.
At some point I will also install a pair of Tektro R340 brake levers, in silver with tan hoods of course.
The bike has been a great all around rider and a pleasure to ride for the last 5 years.
