Not nearly as bad as you might think, around $1400 USD for the top of the line model. They also sell steel ones for around $800 if I recall. I was looking at these because they can accomodate a hub drive without a tensioner due to the way the rear triangle is built. On the other hand, wireless 12 speed sounds pretty sweet so now I'm looking at just buying the carbon version because it's so light. I'd have to redo the saddle post, handlebars, and cabling though, which kinda sucks.

Plus, I already have a Priority Folder I like quite a bit (though it's heavy compared to the Java carbon and lacks suspension).
