just placed an order for a mark v 56cm as well!

yeh, their c-t sizing kind of threw me too. i called them and they put me on this size frame, though the conversation did feel kind of rushed and there was a bit of commotion in the background! oh well, the top tube measurement was perfect and going up to a 59 made me really nervous.

in the infinite posts on sizing iro frames someone had mentioned that they were actually smaller than their stated size (kind of the way the mercier's are sized...) but someone corrected the poster about them not being smaller but being...something, i can't remember.

anyway, i'm curious too.
