Ive been offered a Large size (probably a 61cm) Concorde Prelude Italian frame and forkset.This frame has the through the top tube cable routing. It is actually built up and rideable with a combination of Campy chainring and Shimano RX100 mish moshed parts. Bike has really nice paint and is Columbus px tubing and Columbus Chrome forks with super detail. Selle Italia saddle. Seller is looking for $600-700 for it... How much is the frameset worth? I told the seller that the bastardized mongrel build kit was a real value detraction and he asked me what the frameset was worth... Please email off list to coololdbikes@aol.com or bac2the50s@aol.com Thanks in advance for any help.
