Most of the mounts we sell will work with all of our cameras, however there are a few that do not fit the ContourROAM and are being redesigned. They are the older style of rotating flat surface mount (the square one) and the old surf mount.
Also, the Universal mount will not work with the ContourROAM but that camera already has the same 1/4" 20 screw socket on the bottom thus eliminating the need for the Universal mount for the ContourROAM.
