I question those numbers. I’ve melted a hole in my gloves, more than once, when I reached down to see if my brakes were hot after a long descent.
Nylon melts at 515 F.
I’m 140lb and average to average + in my aggressiveness. I’m sure there are people over 200 who are absolutely sending it. Probably on the same brakes I’ve got.
I don’t think it’s unreasonable for a bike rotor to be close to 1000 degrees in the right conditions.
A race car rotor is probably even hotter though.
