i have been riding on a lopsided scooter wheel on my scooter for the better part of 2 years at school, when i dug out my old schooter form the garage which only had a lopsided wheel becuase it was resting its full weight in storage on it in a 112 degree garage during the summer and 32 degree temp during the winter for about 6 years. When the old wheel finally broke, and i put this one on it was like insta heaven..... never had a smoother and more quieter ride in my life.. or if i did it was so long ago i don't remember. good stuff this stuff!
