197 rear spacing is the latest. Tell me why i may not need or want that.

Latter half of March and early April is always accompanied with used fatbike sales @ the Rocky Mtn ski resort town LBSs (2-3 year old rental/demo pool machines). Likely, you might formulate a list of authorized dealers (of your favorite bike make/model often w/ 1X12 GX systems) and phone vs. e-mail those shops individually. Now after my Mukluk (CF) frame was crunched in a National Park visitor center parking this past summer (hit and run while on the 1upusa rack on the back of our vehicle) I'm riding a Fatback Corvus w/ 1X12, 2.8"X27.5" non-winter rubber.
Fatback Bikes ships out of Bend, Oregon and there is no sales tax with a shipped frame). (If you're looking at a used CF or alloy Mukluk w/ anything cage-fork mounts...what size? I can ask my LBS if any of their rental/demos will be sold off at the end of the season.).
(BTW-rode a '17 Beargrease, on a supported GDMBR trip and encountered the dreaded NM monsoon mud one 24 hr period between Grants and Pie Town and the wider wheel spacing on the machines that accommodate 5" wide rubber would have been better for awhile...biggest problem encountered is the wider rubber (non-winter, 3") ended up dumping the loaded tire mud on top of the chain, cassette and eventually clogged the der, chainring promoting repetitive/continuous issues every time it was cleared).
Addendum: during a training ride for my GDMBR, I encountered JP crushing it, riding south on the TDR-ITT on his Cutthroat (unlike above...nearly like two ships passing in the night) south of Steamboat Springs just north of Radium (Colo. R.) and screamed out 'go JP!'. He yelled "Yo". (and that was the FULL extent of the conversation...LOL).
