Note from the manufacturer:

The 34 T chainring is not compatible with power meters that have a circular spider (e.g. SRAM QUARQ, Power2Max). Use long bolts or bolt covers for the outer chainring. If you are only replacing the inner chainring, continue to use the original bolts.
Combinations other than those listed above are also possible, but these slow down the shifting process and require further adjustments to the front derailleur. Please note the maximum permissible difference of 16 teeth.
