Hmm...

I used to have a '97 Bianchi Volpe, which was Bianchi's (rather lame) attempt at a CX bike. I commuted with it every day, 17 miles each way. Its turned out to be a nice-handling and comfortable bike. I can't tell you what the BB height was, but I'm thinking that the Volpe was a better all-road-all-rounder than a straight-up CX for sure. I only carried a rear rack with a gym bag bungied to it, so for being loaded I can't say how it handled. Overall, it was a fast bike and had quick handling, but it did not look like the chainstays were overly short.

This isnt much, but I hope it helps you.
