Well, If you have a Mini Crawler, you know how much you wish you had Beadlocks. If you're like me and don't want to pay the $120 for a set, and realize you can turn the stock wheels into beadlocks, thanks to the removable rings.... You'd look up a tutorial on cutting PVC to make a grip for the inside.
Looks like Losi released a set to save some PVC troubles

$8 seems better then $120, but you don't get any extra weight and you have to be a bit careful no to strip the wheel screws out
