The XDR driver is 1.85mm longer than an XD driver. Made for Road specific 11-speed rear wheels; it occupies the same space as an 11-speed HyperGlide road driver. The XDR driver allows XD cassettes that are part of SRAM’s 1x road and MTB groups to be installed on a wheel that is spaced and dished for 11-speed road HyperGlide freehubs when used with a 1.85mm spacer behind the cassette.
