Bought some property near Asheville, and looking forward to getting back into some steep gravel rides after a few years off the bike. In the past my lowest gear was 34x32 and not enough. Posted this in 2017 for the same dilemma:

Eventually arrived at getting the 12-36 cassette working, going from 34x32 -> 34x36 but havenít spent time with the change in the mountains since implementing it.

I am anticipating that I will still want an extra gear, something in the 34Tx40 or 34Tx42 range. It seems there are some new options out now that it is a few years later?

A key point is I have a left arm SRAM power meter, so I canít jump to another vendorís subcompact crank.
Entertaining some possibilities if I feel I still want another lower gear:
* The roadlink to allow for 4T extra clearance which should get me 40T in the back. I assume I have to be careful not crosschaining with my 46T front? Has anyone done this with SRAM? Iíd then put something like a Sunrace CSMX8 11-40T 11spd on.
* Diving all in the 43/30x10-36 SRAM Force eTap. Price hurts.

Any thoughts?
I regularly ride hills in the 10%+ range. Sure on a road bike with smooth tarmac I can climb some pretty steep hills with a 34x32 low gear. But on dirt and gravel I want low gears.

A Force 1 RD will allow up to 46t cassette. I would look towards a 42t low cog cassette, you might need to extra gearing at some point so why not just get it taken care of now.
