Why is this one highend? Other than the barest glimpse of a Columbus decal there nothing to tell us the quality of the frame. what is the tubing level? what are the dropouts? what components were on it?
I agree with T-Mar that fork is very likely a replacement for some reason and if Colnago ever did any contrack wotk for Miele I am certain they would not have their own logo on the fork crown.
Too bad your making it inot a Fixie it may be a nice road bike.
