6 months of riding and honestly feeling it was as nice of a bike in terms of riding/handling as any other, yesterday it failed. 96 miles into a 100 miles ride, hit a little rise in the asphalt (not a pothole technically) and heard a 'snap' - definitely the sound of carbon. Initial though was maybe a rock or something hit the downtube. I didn't lose control and kept on riding to finish off the ride.

Checked the bike afterwards and sure enough, major failure on the seat tube approx where the seat post would end.

I have emailed Deng Fu with pictures. Not really too concerned about losing the ~$700-800 I paid, as it was an experiment worth taking in my book. But I am curious what their response will be and how they chose to handle this.

In any case, unfortunately, I don't think I'll go the chinese frame route any more unless there is very compelling reason why this failure was an anomaly.
