Ok, this bike is only 2 weeks old and I have not had the time to get her out to ride much yet, thats why she's so clean. I wanted something different and my buddy had these wheels laying around so we took a drill to them until they fit. They are 12" wheels that happened to be the right offset, no clearence problems. Wheel and tire combo are just a little lighter than the stocks. As for the cost, I got the wheels for free !!! so I didn't mind hacking away at them. The tires cost me $300 delivered.
