Maybe they did fix the QA issue on the upper link and triangle connection. Also possible that they made layup adjustments on the "standard" triangle for small improvements.
This new rear triangle may just be an upgrade for the hard charging and/or 200lb/90kg+ riders where the standard triangle can't manage the lateral forces.
I don't know, I'm not trying to justify it because most of you know I have one the flexes beyond what I think is optimal. Are we the vocal minority?
Yes, people getting frames right now don't have the beefier design but does it move around like it is barely attached? If you have a wheel and seatpost to throw on and to test that would be interesting to see.
Email says in production and finished in mid January, to me that says starting in April and maybe shipped by June. Add another month for paint. I'd like to be wrong on the timeline and get one before spring.
If the bearings are still pressed in from the inside with no way to retain them,, and there are 2 bolts, one on each side, then there is still a design flaw even if lateral flex is reduced.
It doesn't seem like as many people are having shifting problems, but the derailleur hanger is built outside of Sram's 12 speed design specs. For some it may shift ok now, but I have to think it could be better if within specs. And what will happen once things start to wear? I don't know, but I do know mine doesn't shift worth a....hoot, and no combination of adjustments will make it any better.
I gave the frame a chance and would love it if it worked as intended, but I will not be spending any more money on it when I still don't know if I will have a rideable bike.
