This turned up on the intertubes. Regardless that this is a very nice bike, I have some doubts as to wether this is bike is truly ridden by Merckx.
a) The frame looks too small for eddy's large frame, especially judging by the HT. Compare this bike for instance with the hour record bike.
b) The bike shop sticker looks like it came off your local friendly LBS, not something to be found at a pro level bike. Maybe a later addition?
If the owner is on the forum here I off course would be very interested in the provenance of this bike. I don't want to hurt anyones feelings, but some things struck me as odd.
