Yours looks to be quite a bit cleaner than the one I have. I took the cinelli stem and bars off mind so I take those to be originals. Had a right mix otherwise though - Athena bb, cranks and rear mech. Front mech is campagnolo but not Athena I don't think. 105 calipers, shifters, levers and headset. Mix match of campagnolo hubs on mix match rims.
Tis a nice frame though.
