Update. Latest wierdness.. Ride 1, thought id do some research to figure out what was going on... The board seemed fine, I tested the neighborhood and decided I was going to hit a trail. At mile 3 I'm hitting pushback for no reason again. I went a little further, pushback got worse and worse . wound up walking home with my board on a leash. test two the next day, Pushback instantly in both directions from the mount, found several ways to temporarily pacify, or confuse the gremlin but he would always come back. Ride 3 was instant pushback again, I decided I was going to ride anyway. Chris Richardson's sidewalk 180 drill. It was perfect for the push back glitch. The board definitely has to go meet its maker, the problem is as bad as I thought it was. I'm going to require a loaner wheel.
