Thief proofing handlebars

I dont lock up my handle bars, but i dont have any good stuff there. But an idea is if you dont mind put duct tape or paint were you can to hide it. I personaly wouldnt do this but i like my stuff looking good. :o

You can get high security bolts (allen or torx head with a post in the center are the most common), but they are tough to find in the metric sizes your bike would require.

Much easier (and cheaper) is just blocking access to the allen bolts you have. Fill the hole with silicone or hot glue. You can also fill it with super glue and then drop a ball bearing in like in the attached picture. Any of this stuff will be easy to get out with a pick or awl, but that's stuff the average bike thief doesn't carry. Maybe this helps, and enjoy your new bike!!

There's a German company called Pitlock that makes a locking headset adjustment bolt. However, you won't find it in the USA and i'm a little peeved that the company won't take a credit card for an online purchase. instead they require a bank transfer ($ + hassle). how lame is that.

Just strip out the screw heads with a drill. You can then use a straight flute extractor to get them in and out (www.mcmaster.com Page 2673)

I've had success using PC-11. It's a 2-part waterproof epoxy. Comes in two film canisters. Mix a bit from A and bit from B and you get a hard finished product that can be taken out with a dremel rotary tool.

if it is not under my butt or on my shoulder or i can not see it locked up i do not leave it
