Hi, searched and read all threads on this bike. Never knew people were into them that much. I bought (overpaid as far as I am concerned) a 92 Yellow and white rb1. But I really liked these and I have not seen another one in Australia. It is the 62cm to top and 60cm top tube size.
This bike appears to have very few K's on it. Just some small surface rust on the stem and the whole bike is very dirty. Should clean up nice and I will only replace the cables as they have had it and rusted. It lived in Hawaii and here in Australia on the coast.
Would like to know which tyres came stock on this bike. Mine has Tioga "something" S, have to go back outside to take a look. They are in ok condition, black tread with a cloth (I think from the quick scan) sidewall, but I am not sure if they are original. Otherwise the bike is as far as I can tell apart from maybe the bar wrap.
Did they come stock with a full shimano 600 group? mine has the headset, but has a SR sakae seat post.
