I am thinking it is worth the $150-$200 to try it.I confirmed the shifter is the only part of Transmission that is backwards compatible. So if anyone wanted to upgrade their old AXS, they can go for it.
The cost is silly.$1600 for the XO groupset btw. More than double an XT group. Our sport is going to kill itself.
Also, SRAM put a solid bid in for the ugliest brake of all time.
