Interestingly,
Ciocc also has a carbon tandem, in 5 sizes. This needs some looking into. The advertised frame weight of 2600 grams (with a lateral tube), compares favorably to my lateral-less L/M Calfee Dragonfly weight (unpainted) of 2930 grams. Also, it appears to have a tapered head tube, which is a nice, modern feature.

Here's a
FB photo gallery of a Ciocc tandem (I can't tell the frame material). Seems to have good attention to detail.
Here's a Ciocc being used by a male team.
