Providing excellent security for your bike, the Blackburn Sing Sing Compact U-lock uses a clever shape to reduce susceptibility to attacks.

  • Compact-length 14mm-thick steel shackle features a hexagonal shape to prevent the shackle from spinning, increasing resistance to cutting and leverage attacks
  • Lining helps protect your bike's finish from scratches and scuffs
  • Dual-bolt lock mechanism engages the shackles on both ends to maximize bump- and pick-resistance
  • The Blackburn Sing Sing Compact U-lock comes with 3 laser-cut keys and a mounting bracket
