With the popularity of the new SRAM AXS 12-speed groups, plenty of road and gravel bikes are now equipped with rear wheels bearing the SRAM XDR road freehub body. Wahoo has stepped up and is offering a freehub conversion kit for the 2018 KICKR and CORE rear wheel-off direct drive trainers. As the XDR uses the same system, but longer body, than the mountain XD version, this freehub adapter set-up will accommodate both.

At this time we have no information from Wahoo on XDR/XD adapter options for older KICKR models.
