For most road drivetrains (i.e., not 26" wheels, and not tiny microdrive
chain rings) 12 is a better 1st position than 11 (because it's not as
unreasonably high) and in the case of the 12-36, it can easily be
customized into a 13-36 simply by replacing the 1st position sprocket
(and for most road drive trains with 48T chain rings or larger, a 13T
1st position gives you a more usable top gear than a 12, and at the very
top end a 1 tooth gap is nicer than a 2 tooth gap). In my opinion.

Shimano makes 11-34, 11-36, 11-40 11 speed mountain cassettes. The
11-34 and 11-36 are pretty pricey though.

Steve, thanks for the links. I guess I meant hard to find in that
I went to my LBS who did not have any in stock and could not find
any currently available through distributors. I figure this low
supply is due to the surge in sales last year but curious if it
could be the beginning of the industry phasing out of 9 and lower
speed parts moving forward. I'm fine ordering some things online
(mostly through Riv or other small manufacturers that sell
directly) but I do prefer supporting local shops.
I could also swap chain rings but the crankset is new and my
current cassette is older. Seems easier to swap the cassette. And
I'm quite happy with the current steps in my gearing.
Laing, I could fit 11 speed on my new wheel I'm building with a
new model MI5 hub. I have used (and still have in my bin) a SRAM
NX 11 speed cassette/derailleur before. I found the gear range
lacking as it is 1x only. I also tried the Microshift Advent 9
speed. That one I did not like steps between gears as much. I
guess after trying some of the newer stuff, I'm having trouble
seeing the appeal. I can get the gear range I'm looking for with a
2x9. The 1x systems seem to either give up range or are
ridiculously expensive. There's also something about 9 speed
looking "right" to me on a Rivendell.
My main concern is getting parts in the future. I helped out at my
LBS over the summer because they were so busy. This will most
likely be another busy year for bike shops. I think I'll order a
handful of cassettes to tide me over for a while. I hope that as
manufacturers catch up with resupplying parts they continue to
make "outdated" 9, 8 and 7 speed stuff. There are certainly a
greater number of options for cassettes when going to 10 and above.

Note that new Shimano 11-speed mountain cassettes fit on old
9-speed Shimano style hubs - the 11 speed is only 0.05mm wider
than the 9-speed. I just put a 12-46 (I used a Shimano 12
tooth 1st position cog in place of the 11 tooth cog) 11-speed
cassette on my old Phil Wood 9-speed touring hub for my Gus
Boots Willsen. Fits beautifully - chain even clears the 29x2.5
tire by 4mm. The inner large cogs kind of cantilever over the
hub flange

I'm currently looking for 9 speed cassettes for my
Atlantis. I'm hoping to be able to do a tour this year
after staying local in 2020. With touring in mind, I'd
like 12-36 but it seems those are rather hard to find
right now. I currently have 11-32, but I'm riding in flat
Chicago. The 12-36 would give me the same ratios for my
normal riding but get rid of the 11t, which I don't use,
and would give me a 36t, which I foresee using on my trip.
With the VO 46/30 crank I'm using, this gives me a range
of 21 to 100 gear inches, which seems perfect to me. After
seeing the high demand for bike parts in 2020, what do Riv
riders predict for future availability of 9 speed parts? I
found someone with a stash of 12-36 9 speed cassettes for
sale on ebay, do I stock up now?
Also, how much does cassette price/quality make a
difference? I've mostly used cheaper cassettes but
wondering if would make sense to go up to 10 speed to take
advantage of fancier cassettes. The cassette on ebay I
mentioned is Alivio so on the lower end of the spectrum.
I'm using a Suntour thumb shifter in friction so I think I
could make 10 speed work. However there's something about
the ease of setup and maintenance of 9 speed shifting that
makes me want to stay in that world.
