Hi, I've read a couple of the previous posts with regards to sizing, but I guess I still need some more help. I am torn between a 48 cm Redline Conquest and a 49cm Kona JTS. The Redline has a shorter top tube than the Kona, but taller stand over height. Is it true that SO height is more important? How much can I shorten that TT length with the stem and bars? I am 5'4 with a 30" inseam. My road bike is a 50cm Trek OCLV and I think the TT is a bit long when reaching for the brakes. The difference between the 2 'cross bikes is probably .5 inches or less.

I am really excited about cross but the process of finding a bike is putting a damper on things. I cannot find any shops in the area that carry smaller bikes so I have to buy one without trying it. (scary!).

Thanks for your help ladies.
