Currently have compact with 11/32 on the back on road bike and tri bike. Living in Michigan, I've never really used the 34t. My gravel bike is Sram Force 1x with 42t. I want to use Quarq but that would be awkward range of gears. Thus the reason of adding 42t to quarq in place of the 34t and not using the 50t when on gravel (there is no FDR on gravel bike).

Does this logic work or is there some chain alignment issue (or some other issue) I'm missing? Would it be better to just use the Quarq as compact and change cassette on gravel bike?

Any other ideas that don't include buying another PM for gravel bike?

Thanks in advance.
