Since we're conjecturing...
My analysis of the beam construction happened because I had to sand mine down to fix a manufacturing tolerance issue.
Technically, the beam was not the issue, but rather the tolerance on the seat post was such that when the seat collar pinched the carbon supporting the post, it exerted enough force on the carbon (and without the opposing strenth that would have been provided by a properly sized post) to cause a crack.
I don't know who the original owner of the frame was, or why the beam was not replaced under warranty. What I do know is that I *never* had *any* doubt about the quality and engineering of the rest of the frame. The lower end is a solid piece of manufacturing, and in my view is adequate to the task, and safe for use.
I do not believe the same is true for the beam. I have carefully sanded mine down to the bare carbon. I've had it in my hands for hours and hours and hours. After repairing the original crack at the seat post to my satisfaction, I decided to add additional layers of UD to the pivot area. I did not feel confident in that part of the frame before I added those layers. I do feel confident in it now.
Again, I agree. This will be my last post until I actually have something else of substance to report. Either resolution or escalation.
This is the proposal that I have made and have asked my lawyer and others to communicate to TJ/Dimond.
This was initially sent in response to a third party who offered to mediate.

I think I have a possible solution here for all parties. And it's possible that it can be resolved through mediation.
Here is my proposed solution.
I have, at this point, offered several recommendations as to how this design should be fixed. This is based not only on my own engineering skillset, but also on the skillset of other extremely qualified engineers within the bike industry with whom I have discussed this problem.
I believe that the design can be reasonably effectively fixed after the fact. I.e., I believe that existing frames can be modified in such a way that this problem is mostly - and perhaps entirely - mitigated.
I also believe that future bikes can be produced without the likelihood of failure. I think the fundamental flaws in the design as it exists can be fixed. It will not be easy. Or cheap. But I think it can be done.
I am willing to provide a public record of my proposed solution(s) and to solicit the help of other engineers in the industry to tackle the problems about how to both fix existing bikes and to fix the design itself such that future bikes do not have issues.
In exchange, Dimond agrees to make acknowledgement of these issues and to issue a voluntary recall and to offer to either fashion a satisfactory retrofit or to provide the customer with a new frame based around a corrected design.
From the very first, my goal has always been to help make Dimond make better bikes. That goal remains. If Dimond is willing to seriously engage in that process, I remain willing to support that. But those are my conditions for mediation.
Any mediation must result in a public acknowledgement of the current issues and an effective proposal for how to fix them, both current frames, and future ones.
Best,
Jordan
