It's a disc brake frame compatible with 700c wheels.
Here's what it looks like built out:
Here's the frame itself:
I got this frame as a replacement to my previous Sutra 2009 frame. I loved that bike and road it for many, many miles - several bike camping trips and a fully loaded tour from San Diego to Austin. The 2009 model had a known defect in the way they configured the rack mount that eventually failed on mine - which is how I got this shiny new frame as a warrantee replacement. In the mean time, I've moved on to my next machine... My good fortune becomes yours.
BTW - I have a collection of good, used components for sale that could be used with this frame if you don't want to buy them all new, as well (Avid BB7 calipers and rotors, handlebars, Shimano bar-end shifters, break levers, FSA crank that still has some miles left on it, good 9 speed cassette and chain... you could practically build a bike with the parts, but I thought I'd give someone a chance at the frame if they want it before I put together a 'new' bike to sell).
Make me an offer on the bike that will build into your next world traveler.
