www.sheldonbrown.com/lock-strategy.html

and http://quickrelease.tv/?p=327

and then use google yourself. And use the forum search here. Not just because it is polite to do so before asking people for help, but because, frankly, you'll probably get better advice via google. The world's best bicycle security expert has almost certainly written for the web but he is unlikely to answerer your post.

And if you then want to ask questions do so by all means - but include details like the type and value of bike.
