First things first the XC60 is not an mtb, it is a hybrid bike with 700c wheels. So the geometry and intended use is different.
I suspect the tubes are of a different diameter and maybe only 1 or 2 in the main triangle of XC60 are ti??
Maybe there is more information available in the test if the catalog?
Anyway, if you want a hybrid style bike ok, if you want an MTB it isn't one

Thanks again, Rich!
I'll think about it and might look for tests!
Best
