Note that this is the 1231 XPLR cassette. Normal SRAM XPLR 12spd cassettes start at a 10 tooth and work on an XDR driver/freehub. This model starts at an 11 tooth and works on a “normal” Shimano HG freehub. So this is is a great way to use an existing wheel and use it with a SRAM XPLR derailleur.
This is in great condition. I bought it new and used it exclusively indoor with a bike that also stayed indoor. So there should be minimal wear on the teeth, as you can see in the pics.
