Have not made it to the park yet, but had some fun on a ledge that is a tall red curb. Got tossed from wheelbite on my 55 f4 classics though, but i dont want to ride a smaller wheel, so i waxed the bite marks and seems okay. buttery grind and really enjoying these squishy bushings and light pop. skated some pretty rough asphalt but the IKP doesn't seem loose yet. Might be in my head, but seems the axel does not allow the wheel to spin as fast as an Indy axel? Like there is a bit more friction?
