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.
Carbon failure is typically caused by impact and a pedal strike could definitely transfer enough force into the BB threads to challenge the carbon. Unlikely, because most pedal strikes are absorbed by the body. I’ve had 20-30 pedal strikes and have broken the carbon body on pedals twice, but I’ve never considered the frame at risk.
Another consideration with threaded BB is cross threading or misaligned threads. Did you have the frame prepped with facing/chasing the threads to ensure alignment? I doubt this would cause such fast failure.
The crash referenced is likely the culprit. The bike does crazy things during a wreck. But, you would have heard something or felt it if you were still on the bike. I’ve punctured the top tube with the shifter high siding a berm, cracked the chain stay trying to ride through a rock garden, and cracked a rim when a loose rock kicked up off my buddies tire.
All of these events I knew right away there was carbon damage due to the sound.
