my assumption about weight appears to be wrong. If your willing to pay for the expensive cassette it only weighs 368 grams which is lighter than standard Sram 11-36. Even if you go with the "bargian" GX Eagle at $215 , it's only 75 grams heavier, which is presumably offset by losing the front derailleur, wires or cables, and a presumably lighter brake lever with no shifter in it.
