The official line from Sram is that the new AXS road groupsets are only compatible with Sram chainrings. However, in some recent conversations with Praxis, I am told they now consider their current stock of rings 12-speed compatible. This has not gone official on their website yet, but I am told it is coming in the near future. Apparently their new stock of rings are even specifically stamped “10/11/12 Speed” on the large ring, or something similar. Additionally, there is at least one company that sells aftermarket 2x AXS-compatible rings - Carbon Ti.
With this in mind, has anyone tried aftermarket rings with AXS groupsets with any luck? Has anyone had any specific experience with current stock Praxis rings?
The reason I’m asking is that I have a perfectly functional Quarq 5-bolt, 110 BCD DZero power meter on hand, which I would like to use on a new bike with AXS. Obviously, this solution would be significantly less expensive than buying a Quarq unit that is compatible with the AXS chainrings, or buying another pedal-based power meter.
