According to a reply from R&A, the $8,500 also includes two Cyfac carbon seatposts, which list for $218.



Cyfac also makes its own carbon water bottle cages, which are included. They look pretty nice, and retail for $99



So, if this is so (I've asked for confirmation without response thus far), the price is even more attractive. $218 is a reasonable price for a carbon seatpost, but carbon cages are closer to $70.

Reconfiguring the table in the post above:

........................Calfee Dragonfly.........Cyfac Le Duo
Frameset...................$6995........................$8500
Fork......................... $478.........................included
Paint (solid)............... $299.........................included
Headset..................... $120........................ included
Carbon cages (x4)...... $280........................included
Carbon seatposts (x2)...$436........................included
Total........................$8608.....................$8500

Yes, it is a bunch of money, but the frame isn't entirely untested, as it has been used successfully in high level tandem racing.
