I believe there is the old Ciocc and the new Ciocc, a classic Italian moniker that has been brought back to life by new owners. Similar to Specialized, I believe many of these new old Italian firms are design/marketing houses who outsource all but one or two primer-level frames that are made in Italy.
Ciocc seems to offer a $3,600 aluminum-framed model and a $5,600 carbon-framed model. In looking at the frame geometry tables, the tandems with the small stoker compartments (M/S, L/S, X/S) have REALLY small stoker compartments... I mean REALLY small. The X/M is about 28" in back and the XX/L is 29" in back. So, to the credit of Ciocc, they appear to offer these frames in a range of sizes so perhaps they are a bit more 'made to order' than the one-size-fits-all Pinarello tandem was.
