Hey guys, I have an opportunity to purchase a complete Vintage super record group and I was wondering how much I should offer for the set. The parts include a Rear Derailler, downtube shifters, brake levers, brakes Cranks, chainrings, wheelset with mavic rims, 2 extra hubs, but no front derailler. The parts are off of an 80's roadbike and the guy said they're in pretty good condition. Ill be getting some pics of parts and i'll post them as soon as i get them.
