I think these frames are just re-badged asian models. Several venerable european marques (Motobecane and Masi come to mind) have been licensing their names to Taiwanese manufacturers, producing bikes that look VERY similar to the Bassos.

Performance is selling these framesets for $1,000...That's a LOT of money for a Taiwan frameset. Go to gvhbikes.com and you'll find comparable asian framesets w/ Columbus tubing (badged as Raleigh mostly) for like $350, or an American made Cannondale CAAD5 for $535.
