Maybe so. If it was I don't remember it happening. That would be the chain ring side. There is a scuff in the middlish of the down tube.

The day it fell apart was a slow flowly ride with friends. I fell behind taking some pictures then put some power down to catch up and noticed something was wrong.

I added a photo of the full build for those who are interested

Got my FM936 near the end of June. Size Medium felt like my old trek M/L once I slammed the stem. I am 5' 11" I was comfortable on the medium, but I wouldn't mind trying a large. My build ended up around 27lbs. I put about 180 miles on it in July. The bike was fun to ride, and very capable in both technical and rough terrain. I felt like it was a little ridgid when landing jumps, but that was probably a tuning issue.

Everything was going great till the bottom bracket started to separate from the frame. I had 2 events that may have contributed to it. 1) A pedal strike, not an especially hard one or anything. 2.) An end over wreck off a drop. Not sure how it could have affected the BB though.

Carbonda has been somewhat responsive. They have not offer to replace it or a discount on a new frame. They have offered to analyze the Frame if I ship it back, but that may be cost prohibitive. Cheapest ups shipping of the lower section of the frame is $134. I have sent more detailed pictures and am currently waiting for Wing to respond.
