i am seriously thinking about getting a Jamis Aurora for fun riding in my area (very hilly) and some for touring of California (and beyond?). But since each bike company seems to have different ways of measuring their frames, does anybody know how Aurora frames compare. i am 5"10 with about a 32" inseam. My last roadbike was a 54cm (it was a steel framed Marin), which almost seemed a tad too small. Around town i ride a 20.5" giant Mt. bike, which seems big on paper but works great for around town. Also, i have a really tight IT band which i struggle with, even with aggressive stretching (though it is finally loosening up some). Any suggestions as to where to begin in frame size? Thanks.
