I see most of us short women on Specialized 29ers. From what my LBS told me they felt Specialized was leading the way on small geometry. Of course Willow Koerber, Emily Batty and Heather Irmiger are all about my size and have been rocking Trek 29ers.

From looking at geometry charts I might be able to ride a Specialized Crux. Not 100% sure, the only person in town I know with the 46cm is one of the wrenches at our shop who is quite "compact". Our local rep is pretty darn cool though, I could probably get a demo if I liked. That is my next bike on the wish list.
