This bike showed up on Craigslist. Listed as "specialized road bike" Price seems reasonable, but I'd like to know what it is.

It appears to have Cantilever brakes, so I think it is probably a Cyclocross model, but I'm having troubles identifying it.

I sent an e-mail to the seller, and the reply was "Call", which sent me to voicemail.

I've inverted the photo for better viewing.
