I would guess three at least. I've seen lesser bikes go for more. There's some amount of imfo. on Miele in threads in the forums and on the net. Posts about the bikes have come up in the past week. Miele's gone now, he was a very traditional frame builder in Canada using Italian approaches, he made other bikes also. The CO. went on without him to make other models. His work is still highly regarded. Those who know of him would like that frame. Colubus SLX was among the very best tube sets available in the '80s and still highly respected and continued to be used well into the 90s and beyond. The right person could give you more but I would have to agree that a somewhat narrower audience than the more well known bikes . Your bike's in fair shape and I think that you'll gain more by selling the frame seperately. Your bike is the real deal, it's what you say it is. Less than two hundred .. they can go .. and even that's too low. You may want to list its metric size.
