Scott Breakaway

Confusing title. Ritchey makes the Breakaway cyclocross bike with the seat clamp cluster coming apart, allowing you to pack the bike into a small box and get it on an airplane. People seem to like them and one woman I met recently said that she toured across Scandanavia on one. So, I'm sure they're durable.

Scott is apparently trying to compete:

From http://www.scottusa.com/us_en/product/8294/45036/addict_cx_rc:

"The Addict CX RC and Addict CX framesets feature an integrated seat tube to shave approximately 100 grams off the complete bike. These are the kinds of details that produce the lightest cyclocross frame on the market."

Also, the first all carbon frame with carbon seat-mast cyclocross bike that will dissasemble itself when you re-mount it, allowing you to pack the remining carbon shards into a little tiny box and send it back to Scott on an airplane.
