AM831 - The flex-fix

[promoto]

I replaced all the bearings on mine when I fitted the new rear triangle and its been fine , The original bearings are low quality and some of them were already feeling notchy after only a few rides. I've now covered almost 300 miles of local trails and bike park trails without any issues.
I have converted to a mullet set up which i really like

I have now been riding the AM831 4-5 times on trails and it fells nice. I haven't jumped or pushed it hard downhills though. This weekend i rode with my son and we pedaled uphill on a road and he said, "Dad, it looks like you have a tail, its wiggling, I think you back wheel is loose".

I stopped and checked the wheel, everything was tightened but when I took the wheel in my hand I could flex the rear triangle a lot. I felt his rear triangle and it was stiff (LCFS911) and my wife's rear triangle was also stiff (LCFS713).

I haven't felt this when riding but it made me feel insecure, can I trust the bike if things go rough. I have done the "flexfix" but I can not imagine that it was even flexier before that. Could i have "flexfixed" it wrong or is the result not better than this.

Made a video of the flex.



Hoping for helpfull feedback

I don't see an embed and I don't see any link to YouTube. I seem to recall this having been an issue in the past for others on this forum.

I can see the vids on mobile, but not on desktop.
Thats a lot of flex. Hope you can get it sorted without having to buy a new rear triangle.

Im not ready to spend 300 USB + shipping for a new rear triangle on this frame that I don´t really trust, will it be 100% good or just quite alright... . I would rather move everything over to a frame I trust. (LCFS947...) All you that have bought this frame and the the flexfix, does your frames flex this much? Is there a danger of riding with a frame this flexy?

Went through a a period of financial hardship- I bought this frame in the first group buy, just now getting around to building it. Is this still a viable solution? If so, can anyone point me to the most current resources? Or should I just get a better frame?

I have the new rear triangle and seems to be holding up ok, fixed the flex issue for me.

Do you think its worth the money at this point though? I've been reading a lot of people saying they aren't too happy with it, and I don't want to put more money into it if Id be better served with another frame or even a whole bike. I don't have any parts aside from some brakes. If I spend another 2k on parts and stuff, would i be better served just buying a Vitus, or something used or something?
