I earlier outed the auction being held for an early to mid-80's Alberto Masi time trial bike:
Steve asked: "Are MASI TT frames supposed to have bent top tubes and seat tubes such as the one you refer? "
I have only seen one other time trial Masi like the auction one with curved tubes. It was however quite common for the period in Italy, so I have no doubts about the authenticity. BTW, The seller also owns a Bianchi Folgore from 1940, another Bianchi with Simplex dropouts and gears from 1950, a Masi GC from about 1970, plus a number of city bikes ranging from 1907 to 1960. I have already asked him if he would sell any of them, to which he answered a very firm NO!
