I'm treading carefully beacause I don't really want to diss this retailer, as I'm not fully au fait with their retro dealings, but as I actually went there, this is what I found
1. The cinelli frames are unstickered - why? I don't really recall them like that BITD. Is there something there that isn't legit, so there's no specified name? Big question, i'm suggesting nothing
2. Who are SAB? Not a name I remember to render them old stock, and they sell modern carbon frames too. But then, maybe they were a small manufacturer BITD who didn't get worldwide status.
3. Some of the steel frames were a bit too modern for my liking. So there were head lugs and then lugless set clusters with shot in stays on the same frame.
It all seemed a bit pastiche trying to tap into the retro hipsters market. It reminded me of the modern VW "aircooled" camper van. From a distance looks retro. close up its not the real deal I'd be buying. But like DavidB hinted at, once you get to 90's, its no longer retro to me, but would be to someone younger.
I suppose what I'm getting at is that they didn't look to be NOS - more like modern with a retro look.
