And happily for all, tubular glue won't melt at the sort of rim temps experienced by pros riding at max pace down steep mountains .... and I am sure that in the cases where I saw riders in a broadcast race lose a tire and the announcers---themselves ex-pros---said that due to extreme heat of the pavement and the heat from braking, that the tubular glue melted, they were lying ... in the pocket of big Tubeless, for sure.
