I'm very pleased to say that John Loughlin (another Bike Forums guy) and I have just
fired up a Kickstarter on our TiGr titanium bike lock project.
It's about as tough as a Kryptonite (we're looking to get that confirmed by a third party with help from our Kickstarter backers) at a quarter the weight, it goes through both wheels and a parking meter post, and it's designed to look like it belongs on an object as elegant as a bike.
Please help us get the word out!
