| Thanks for the tips. I will see if I can find a place. Joe, I use a jump bar that attaches to both kingpins. When I get up on my jump bars for tricks, it must pull against the kingpins. Also, when I grind, I catch the top of my kingpin, which also puts pressure on it. I want to know if Jay has this problem? He is always up on his plates doing slides and I think he has my plates. Jay?
