That's a sharp looking bike, but my biggest problem is the very low slope to the top tube. It isn't too much different than from a traditional horizontal tube. To get up to my optimal range top tube of 560mm, it puts me on the 53cm Casseroll. Unfortunately, that size has an 804mm standover. And it isn't going to be very much lower right in front of the saddle.
I've looked at a number of bikes like this and rarely find one that fits.
I do fit the Marin Mill Valley bike, in their 17" size. Could pop all the way up to their full carbon, DuraAce RD, hollow crank arms, etc. Could probably get it at a price close to what it would cost to build the Gunnar Rock Tour. I like the Mill Valley, except for its 52/42/30 crank. That's pretty tall gearing for me.
