The SRAM XDR Freehub Kit is a driver body that converts compatible hubs to the SRAM XDR interface for 12 speed road cassettes. XDR is longer than XD to suit road hub spacing, and XD cassettes can be used on an XDR driver body with a 1.85 mm spacer. Kits are hub specific and must match the exact hub model such as Zipp ZR1 or 176 and 177.
