Tex-lock

I actually went to their "opening party" here in Leipzig a couple of month ago. It really is a great product! This is from their site:

"At the heart of this innovation “made in Germany” is a textile rope made of high-performance fibers. The resulting flexibility, lightness as well as the special look and feel make tex—lock the ideal companion – for sure, because the tex—lock protects your bike from theft just as well as a conventional bicycle lock; its soft surface furthermore prevents scratches and rattling on your beloved bike. And on top of that, it looks great!"
