dude we bombed a small hill which was about 30 seconds long, he put his brake on right at the end and i went over and litterally the urathane was pooring
out the side and just fell off. then another part of the wheel was perfectly cured and was hard as hell to get off. if you were lucky you might get 1 good fully melted but good luck.
if your going to get wheels i would advise low pros but there kinda slow or pro model wheels i love them. they ride kinda hard though but you get use to it super quick. i love them.
