Hello! I have recently acquired a S-Works Shiv TT Disc frame to build up. I want 12-speed SRAM electronic shifting for the quick swappable batteries and wireless shifters. I also want a 2x drivetrain because this bike will be used on ultra distance races that may have some moderate elevation where a small ring will be needed. However, SRAM doesn't offer any standard or large size chainrings for a 2x system unless you buy the ones with an integrated power meter. For specific events, I can see wanting different gearing with the big ring being anywhere from 48 to 54t to maintain my desired average speed without leaving the big ring or spending a lot of time at extreme chainline angles.
SRAM only offers their 2x chainrings in 52t, 54t, and 56t as the SRAM Red integrated power meter, none of which are "aero" chainrings like their 1x offerings. I definitely don't want to pay for a new power meter for different chainring sizes. What is the best combination of cranks, power meter, and aero chainrings to use that would allow me to use a non-pedal power meter (I already have specific pedals I want to use) and still have good compatibility with a SRAM wireless front derailleur?
