I voiced groups concern on this frame to eBay seller. Here is his reply"Response from keano50 Item: colnago 30th anniversary campagnolo gruppo (7191707633) This message was sent while the listing was active. keano50 is the seller.
Read the ad. The frame is a 88 master, the gruppo is 83 30th anniversity. I make no claim otherwise. I bought the gruppo in the original box from Marcel Calborn in 85. if it's wrong then I have been had. I did not know you could not mix parts to be able to ride."
If a 88 then past cutoff
