Is there a cassette available with an 11-tooth start so I don’t have to change the driver on my rear wheel to XD?

SRAM offers a PG-1230 Eagle cassette which utilizes the HG splined driver body interface. This is compatible with all of our Eagle drivetrain parts as part of the Eagle ecosystem. However, for optimum performance the XG-1275 cassette is used in the GX Eagle AXS offering.
