I agree that it is better to trust Quarq than Praxis recommendation here. However, if you strictly follow Quarq recommendation, you should use only a SRAM drivetrain:
Chainrings: SRAM TSM
Official Compatibility: SRAM RED, SRAM Force, SRAM Rival and SRAM Apex Front Derailleurs
As per FAQ
I have an 11-speed drivetrain. What are my options?
We have customers successfully using the following chainrings on Quarq power meters with 11-speed drivetrains:
Rotor Q and No-Q in 130 BCD and 110 BCD
Stronglight CT2 in 130 BCD only
FSA Pro Road in 130 BCD and 110 BCD
Wick Werks in 130 BCD and 110 BCD
I personally have a Quarq Riken with 52/36 Praxis Clover rings. No problems, except for the porky weight…
That being said, my next PM will be a P2M or a Rotor PM (and Praxis rings).
