I'll check them out when I get home.
My Trek 730 still has the stock 36 hole Matrix Journey Rims, I measured them before I attempted to install the 23mm tires and to my surprise they were only like 16 to 18mm wide (inside width). There were no issues installing the 23's, they did not flatten out accross the rim and I like them. I can tell no difference in the comfort between a 35mm or 23mm on a 20 or 25 mile ride even at 125lbs. of pressure.
I would imagine one negative aspect is durability, but the speed and time savings is worth it in my opinion.
