I have some Shimano 600 parts I pulled off an older bike I had, cleaned em up really nice and they're pretty good. Make me a decent offer for any or all of them.
Front and rear brake calipers with pads with lot of life in them. Springy action on these.
Rear derailluer
Brake levers (note: NOT STI shifters)
e-mail me for pictures of it you're interested....
