This maybe a newbie question...
How can I lock my RacingHart GX wheels? There's a small
'cap' covering the lug nuts, held on by allen head screws covering
five regular ole' lug nuts. They are in recessed areas, but a deep socket works fine. I've never used locking lugs before... not sure
how these things work.

 

YOu mean Cx wheels i'm guessing. But anyways, you can buy wheels locks from most any wheel vendor. I'm not exactly sure how they lock them. I'm about to order new wheels myself and they are including some. I would recommend getting something so someone doesn't jack your wheels

 

all wheel locks are, are a specially sized lug nut that comes with a socket that fits it, simple way to get those off is hammer on a standard socket and unwrench, you best bet would be to get wheel and tire insurance, also good if you curb a rim or have tire issues
