I bought em and I want them to roll faster than they do straight out of the box. What should I do?
You have a couple of options. First let me say that with use they will “break in” (wear down) and expand the center of the rubber bearing. So, over time they will get faster and faster, which can be controlled by tightening the axle nuts. H-o-w-e-v-e-r, for those who have advanced more and want a slightly quicker roll, try some decent oil (motor oil is fine) and rub it on your axle, then put on the bearing. For more aggressive adjustment for speed, we recommend you try drilling the center with a regular handrill and a 5/16″ (7.94mm) bit, or even slightly larger. Remember – its easier to drill out more rubber, than put it back (you can’t!) so do not get too wild too quick! A little bit of drilling, makes a huge difference.
