Coming soon to bikes near you- double hooked rims!

So by using hookless rims you create a pinch flat possibility? Why would anyone use a rim that increases the occurrence of flats? That logic escapes me.

Are they 'pinch flats' or 'burps'..With tubeless, I think the later..

For sure. It's seemed odd to read and type 'pinch flat' for tubeless.

This is another "if youve never missed a flight you are spending too much time in airports". Rather than trying to completely eliminate the possibility of pinch flats, it might make more sense to balance acceptable probability of pinch flat- and not to mention rim damage- with tire volume and pressure considerations. Having a rounded edge gives you a bit more margin.
