Yeah, but why? It's not for no reason. Until that's answered, you're assuming unknown risk if you need/want to run at (still quite reasonable) pressures higher than their stated max.

You quite often tell people to toss relatively new tires if a cut brings up any question of safety - it's just a tire, it's not worth the potential hospitalization, just buy a new one. While a current LB owner will probably see this revision to very low max pressures differently, based upon their own experience, for a prospective buyer, this is a perfectly legitimate reason to cull one of these wheelsets from consideration - it's just a wheelset, there are more out there, it's not worth the potential hospitalization, just buy a different one.

Quite frankly, I was very hot on an LB wheelset for some time and I was very interested in hookless, but the lack of documentation, compatibility, etc etc gave me pause (along with the lead times - I'm impatient like that). Seeing this now makes me feel like I made the right move in spending a little bit more for something with better support (documentation and service) and availability. Yeah, I know - YMMV.
