It's actually a Diamondback I picked up from REI.
I think I've found the problem. There is somehow a small gap between the sprockets, combined with a very slight warp to the 2nd sprocket. This may actually be a product of the event, but either way it's an issue. I'm going to have them repair it as it's only about a week old. I think the initial problem was a poorly adjusted front derailed, and the gap.
