I just unwrapped what I believe to be a very early Klein Team Super and I am surprised how little I can find online about these bikes. I was in the Bike biz when Klein first started selling frames and I remember the buzz about these unique, uber-expensive bikes. This particular one is unusual because it has no front derailleur bracket and has 120mm spacing for the rear triangle. It has ho-hum steel fork in factory paint and the components are early-70s Nuovo Record. Obviously, the bike was built up with used parts or stuff that had been in stock for awhile, because I think Klein first started selling frames in 1976. I cannot find a serial number in any of the obvious places, though I haven't pulled the fork yet.

Can anyone shed some light on these early Kleins? The 5-speed rear spacing would seem to place this as a very early frame. Any insights will be appreciated. Sadly, this frame is also cracked, but it would be nice to know something about its history.
