Well, I was riding along, did a jump, and my wheel went flying off after I landed, and my rear wheel bolts or whatever you call them went flying too, and I couldn't find them
the best way for front is to get a rollorblade axle, it fits real nice. so if you fond the width of the axle for the front youd need to find the length thats all. and whoever said 5/16 i think was right. just fit the bolt into a drill bit holder and whatever size it is it is.
