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

Please note: Blackburn products can only be shipped to the U.S., Canada and Mexico.

Imported.

    Comments about Blackburn Sing Sing Compact U-Lock:

    Bought this lock due to its size and durability. So far, I'm very satisfied with the lock. The only downside to it was the bike attachment if you wanted it to be stored/attached to the bike while in transit. The locking attachment wasn't greatly designed so I just tossed it out. Instead, I attach the lock to my backpack. It's easier to access for quick lock-n-go process. If you are the type of person who would prefer to have the lock attached to the bike while riding, then buy a Kryptonite instead since their lock/bike attachments are better. However, if you don't mind attaching the lock to your waist, backpack or just hanging from your handlebars then get this one. It's easy to lock and unlock.

    Comments about Blackburn Sing Sing Compact U-Lock:

    The plastic can protect your frame well, but mounting bracket is the weak point. Mine was broken after a month.

    if you'll not use the mounting bracket, this is the best lock.
