I've been looking around, and indeed, they do make some beautiful stuff.

More info about Cyfac here and here. Cyfac had a booth at NAHBS, but didn't bring a tandem (they should have!).

For the adventuresome, here is a Cyfac Le Duo Carbon Tandem 2010 Frameset in Indonesia for $4289 USD, with free shipping.

Hmmmm...what's with Indonesia? Here is another 2010 Le Duo Carbon Tandem for $2940, and $200 shipping.

Here's another carbon Cytec, for $4800 from Trek Bikers Co. a 'Manufacturer, Distributor/Wholesaler' in Singapore. The availability of these frames in Asia suggests that they are being manufactured there. The $4800 cost is about half the $9800 price at R&A, suggesting a wholesale vs. retail cost.

Here is a non-discounted Cytec Carbon at Amazon, Japan, for ￥ 957,000 ($10,357).
