Phoned Hope and they said the problem was with the Maxle lite
Surprisingly enough, Rockshox say it’s Hope’s fault 😉 Bit of both really, Rockshox correctly say that the maxle isn’t supposed to be loadbearing in that way and functions correctly, Hope correctly say that Rockshox changed the maxle design and that their product worked OK before the change. I gather DT have a hub that does the same.
But, the fact is the things still snap more than they should even with a solid 12mm axle like a Hadley or the one in my Ellsworth, not just with maxle lites. Just a case of not enough metal, the exle’s got very little strength in it.
Doesn’t worry me too much, I just stuck a spare in the toolkit and when it breaks I can swap it easily enough, and Hope’ll replace it under warranty. I wouldn’t run a Pro 2 with a tapered maxle lite though, it’s just asking for trouble.
