Got these wheels some time ago, but never got around to doing anything with them...until today. These wheels were going to be for a new build. Couldn't wait and decided to mount them on one of my completed boards. Swapped out my 97mm for these 100mm's. I love the look of the fatter wheel. They still dwarf my other board with the 107mm. Good thing about this swap is there's no need for a spacer between the wheel and pulley. Haven't tested the wheels yet....waiting for the rain to stop.
