Hey! Look what I found in my Vicoden induced boredom! I was just checking out these groovy custom headset caps, and tada! ID built into your spacer. Might come in handy if your bike is stolen too. I mean, the average crackhead trading your bike for a bag isn't gonna bust out the hex wrenches to remove the spacers, right?
