I have to say, the hunt wheels I've been using were a revelation after using various tubeless rims (mostly velocity A23) for the last 5 or 6 years. The H section (as they brand it) profile completely secures the bread so that you can deflate the tyre completely without it unseating and then needing a blast of air. Gather their rims are available separately but look a bit dear, I understood them to be from kinlin, but don't know if a kinlin branded rim is available with that same little shoulder.
Hunt seem to use several rims, but their most obvious wheel sets used the 31T, which has the same internal profile as the 22T and 26T. They’re not entirely locked on, but tyres are pretty secure once they’ve had chance to settle and the sealant helps too of course.
Elsewhere you can read that I managed to ride 10+ miles on a very deflated rear, including a descent of Greenhow Hill without the bead of my Schwalbe One unseating. It had been on a long time and I hadn’t topped up the sealant - my mistake. At Pateley Bridge I stopped and put a tube in. Not particularly difficult with a couple of tyre levers.
I did manage to damage the rim (31T), but blame that on a particularly heavy and fast pothole with no tyre to cushion it. Overall a strong rim that works well in my view. When I get chance I’ll put a new rim on the wheel as it’s on nice hubs.
