[QUOTE=bingham333;14451388]but what can i do about my stem, bars?

@bingham333

On one of Hal Ruzal's bike locking video, he showed how he had epoxied a ball bearing in the recessed area of the hex bolt that held down his stem. It prevented someone from quickly twisting an Allen wrench in there. I guess you have to remove it with some solvent if you (meaning the rightful owner) want to take it off.

Also, I recall seeing somewhere, either on one of his videos, or some post on bikeforums, where someone had some bolts with non-standard heads. I can't remember if they were those star-shaped one or something else.

Maybe those two options would work.
