I recently came in possession of a Fastab track bike I believe to be from the 70's. It's super light, just under 18 pounds, steel frame, TA cranks, Fiamme stem, Ruban Bleu tubulars. Of course looking for a price but also any new information would certainly be appreciated!
The only info I've been able to find on Fastab was here in these forums. Essentially Fastab was a custom frame and bicycle company run by a man named Tom Boyden in Garland Texas in the 70's.
