Its not that vintage, maybe late 80's? Anyways, its a Nishiki Riviera GT, Tange Infinity, full Suntour LaPree with Dia Compe frog legs and levers, and a Sugion RD biopace-ish crankset. 5spd freewheel on a 27" wheelset. Looks brand new, and was only $70
My current thinking for updating it is:
Sun M3I 27" wheelset
Shimano 105 hubs
9spd barcon setup
new ROUND chainrings
shimano 600 threaded headset
So far I have a Nitto Radonneur bar and Technomic stem that is working out superbly, with some Fizik gel under the cork tape on the tops. The bike rides great as is, but the chainrings are driving me nuts and I am thinking over long distances I am sure I would enjoy the extra gearing of a 9spd setup. Any thoughts? I'm wondering if I could just use the current Suntour friction DT shifters with a 9spd setup, even?
