Hey Muirenn - Thanks so much for your help! I actually prefer the mens colors/design, but I guess I didn't even think a mens bike was an option until recently. Seems silly but I kinda just went with it. I originally measured my inseam with a book, but I just did it the way you said and actually got 31''. Hah. My femur is about 1.5'' longer than my lower leg.

And yes- that organization is great. I actually volunteer with them! They really specialize in getting people their first commuting bikes though. I currently ride a Giant OCR1, but it's a tad to small with a TT of about 50cm.
