We first heard about the TiGr lock back in May of 2011, when it was still just a Kickstarter project. But now the TiGr is ready to roar and roll. This 23-inch titanium strap provides a secure lock around the rear wheel and a bike rack, or even street post. Unlike other materials titanium is both strong and flexible – the result is that it can be harder (more difficult) to cut through than steel chains or even a U-Lock.

And while it doesn’t come cheap ($165) but it for those with titanium bikes would you really settle for anything less?
