I'm finally doing it, I'm going to sell my extra bike. Posting up the frame/fork/Dura Ace headset for $600. I plan to sell off the rest of the parts and it is still complete so I suppose I'd sell it that way as well. I think it's a 91. It's in great shape, no rust in the BB area or elsewhere. There are some paint scratches, I tried to show them in the pics below. It's a great riding frame, if you've never ridden a Merckx they're' a treat.
BTW, I have a load of parts if someone wanted to buy the frame and some stuff to build it. I've got Aksium's, Ksyrium's, King/Archetype's, 38mm carbon clinchers. The current build is 10 speed 7800 with an FSA crankset and Cane Creek brakes.
