This is what happens when you mention wanting these to multiple people who later think of them as an easy/"cheap" gift. I now have 2 sets of these to sell plus the set I installed in my bike!
13$ each (includes shipping in US) - 2 available.
As far as I know these and the "Rocker Lockers" sold by DK are the same thing. You can use the search function and read about the drama/copyright claims on the forum if you're so inclined. Or you can just buy these from me, save a few bucks, and quiet your "ticking" top end.
