Thanks for providing the info on your bike.
I looked at the specs on Nashbar's website, and the top tube for the 58cm was listed as 59.5cm. Is this correct? I was thinking of getting one in that size, but the length of the top tube might be too long for me. Perhaps I could make it work with a small stem. Also, if you have a tape measurer, I would appreciate it if you would tell us what the stand over height is because Nashbar didn't list it.
