yep - could it be 26.8? mmaaaayybee....it's hard to tell the hole is a little out of round - I would put it 26.2/26.4mm seat tube.

Someone mentioned that the cinelli seat tubes were this diamter because there is a brazed in sleeve? would anyone have a picture of that?

Kurt - yes, for the right price, it can go to the "kurt's steel bike recycling fascility" lol...

And - what is Falck tubing? Where was it used? When? and by whom?

Thanks all...so now with my new found lovely flush broken off tap in the drive drop - I'm looking for those little spacers that one uses on a bike that doesn't have dropout bolts- anyone know where to get them? I saw a campy pair sell on ebay a few weeks back for around 60 dollars or so, but that's sooooo rediculous - there has to be another way.
