The 560G is a high-security lightweight titanium bicycle lock. The only lock made from grade 5 titanium, the 560G weighs 1.2 lbs while being able to defeat any hand tool.
No matter how good of a lock you have, always practice common sense.
1) Lock your bike somewhere visible and high-traffic.
2) Lock the frame and the rear wheel to a sturdy object.
3) Lock your front wheel too if you're able.
