Just figured out, that the BCD is too small (94mm) for a Quarq PM.
The only Pm option that would work on 43/30 is apparently using the Rival Powermeter single sided crank.
Not super happy with that option…
Any other ideas?
I paid 4iiii to install their PM on my left crank, I think they might be able to do the chainring side as well. Might be worth checking out.
