I have a question regarding the following Ebay auction for a Tomas road bike frameset:
Tomas Stahl Columbus, nicht Colnago Tommasini - Item number: 3658403471
This is at least the third (Italian?) manufacturer name that I have seen on mid 1980s bikes built with Columbus Aelle or Aelle-R tubing, that shares the EXACT same slotted cut out pairs under the b.b. shell, and seemingly the same triangle lug windows. The other two bikes are: some of the mid level Torpados, and a Gavel that Matteo a few months ago. I saved detail comparison photos of the Gavel to a couple of Torpados, already wondering back then.
My question is: are these lugs and b.b. shells simply some typically used frame parts in Italy in the 80s, or is there perhaps some sub-contractor connection (i.e. - they were all built in one unnamed shop)?
Surely, others have seen these features before as well, so I'm hoping for some experience and wisdom. Thanks very much...
