I left my onewheel bearings in for 1,100 miles. Till I started hearing the dreaded clunk on the non-removable side. Shopping around I found these. For the price, and Quality. You can't beat them. They are installed, the board feels more nimble, these should be the OEM. The mail man forgot to pick them up when they where supposed to (to ship to me). The business didn't play around, they overnighted them after the mess up. I use my pint as a main mode of getting around. I'm very happy. Just wish I would have bought more to be ready for next time. All and all your reading this instead of riding, read no more.
