I hope I'm not queering anyone's pitch by starting this thread, but from what I can gather, this is a bike which deserves to be acquired and treasured by the right rider, and since it's listed in a weird place on eBay, some of you will probably miss it:
It's got an interesting mix of components (Campy crankset, Sunshine hubs, Suntour Superbe derailleurs and brakes), and obviously spent a bunch of years hanging in a garage before going through an estate sale ... and the seller obviously has no clue of what they've got.
The componentry led me to do a little digging, and I gather that Cecil Behringer was an innovator and longtime frame builder in Minnesota who is revered in some circles as a god. He collaborated with Pino Moroni (he of Eddy Merckx "The Hour" bike fame) in working on the use of titanium in bikebuilding back in the 60's and 70's. The brief Classic Rendezvous page on Behringer, including some pics of two gorgeous Behringers, is at this link:
So ... any small rider out there who wants a piece of American framebuilding history?
