yes - the Kona has a smaller stand over height (the top tube is lower) than the Jamis

FYI- the thing about cyclocross frames- It isn't really the fact that the bottom bracket is high that makes the top tube any higher - what it really does is make the seat tube measurement smaller...... so a "bigger" bike measures out to a "smaller" size. A 44cm cross bike is really about the same size as a traditional geometry 48cm bike if you are looking at stand over and TT length.
Seat tube is just kind of a convenient thing to measure a bike with, but it causes a lot of confusion..... compact frames and cross frames tend to measure smaller than traditional geometry frames. Which is why I have a 47cm bike, a 44cm bike and a 48cm bike that all fit me.....
