I recently took over an FFWD RYOT 55mm wheelset from someone. This wheelset was equipped with a Sram XDR Body where I ride with Shimano. I contacted FFWD customer service to order the correct body. When I received the body, it turned out that an end cap for a 9mm quickrelease was included instead of an end cap for a 12mm thru axle. I ultimately had to order this end cap elsewhere to get the body to fit my bike.
