I'm working PT at an LBS and was flipping through our new 2011 printouts -- lo and behold, the first major brand to carry a women-specific cyclocross bike is about to arrive! It's not on Giant's consumer site yet, but there's a write up at CX Mag here. It'll be called the TCX W, due out August 1st.

Alas, it tops out in their size M, which is quite likely to be too small for me. OTOH, it'll keep my employee purchasing more under control.
