I don't like those - the setscrew scratches the aluminum and ruins the anodizing on the adjusters. And, I might add, they're really not that blingy anyway. A greatly diminished return, IMO.
LOL some clear silicone is going to 'foil' a would-be thief? Doubt it. You can pick that stuff out with your fingernail. JB Weld on the other hand, will foil the thief. Who has the time to waste stealing fork adjusters anyway? Most punks just like to run up to the bike, kick it over, and run away. They'd rather damage it than steal it. Anyone who has any real knowledge of what bike parts are worth will not waste their time stealing fork adjusters, that's just silly.
