The Blackburn Folsom U-Lock is a hexagonal 14 mm hardened steel shackle with anti-scratch liner. The hexagonal shape helps prevent the shackle from spinning, which effectively doubles its resistance to cutting and leverage attacks. A dual bolt lock mechanism engages the shackles on both ends, making it bump proof and pick proof. Your bike isn't going anywhere you don't want it to.
