I have these in 38s and they were great. Easy set up and running them tubeless. Wanted them in the 42s, so much trouble setting them up (tried 2 wheel sets) and they still deflate every night. Had pin holes that eventually sealed up but the bead just doesn't seem to want to seal. Does not lose much air during ride, it's still a pain
