A DT Swiss XD DRIVE SL freehub body is a conversion kit that allows you to replace the existing freehub body on your DT Swiss Ratchet System rear hub with a body compatible with SRAM XD 11- and 12-speed cassettes.This kit enables you to use the more recent SRAM XD standard, which is a direct replacement for the older Shimano/SRAM 10-/11-speed freewheel bodies.
