Lock your bike up and forget about it, because the Blackburn
Leavenworth U-Lock is pretty much bomb proof. A hexagonal 14mm steel shackle with anti-scratch liner has a 10 ton cut-strength. The hexagonal design prevents the shackle from spinning, which effectively doubles its resistance to cutting and leverage attacks. A dual bolt lock mechanism engages the shackles at both ends to make it bump-proof and pick-proof.
