  • SHACKLE: 13mm hardened steel shackle
  • WEIGHT: 1.1Kg
  • DIMENSIONS: 200 x 130 x 35mm
  • MATERIALS: Silicone overmoulded plated hardened steel U-lock



  • Security Rating: 90/100
  • Body:  Investment cast steel, with compression moulded silicone outer. Injection moulded engineering plastic, UV painted exterior
  • Scratch Protection:  The entire inner perimeter of the Strongman is overmoulded with UV- resistant silicone rubber. This material provides a non-toxic solution against scratches and dints on your bike.
  • Secure Mechanical Assembly:  The main advantage to a single-piece investment cast lock housing is that it forms a highly-secure mechanical assembly by reducing available points of leverage.
  • Double Dead-lock:  Double locking mechanism secures both sides of the shackle, providing a robust, high security solution by ensuring the shackle cant be cut once and twisted open.
  • Lock Barrel Security: High security disk style lock barrel, designed for a minimum of 5000 key combinations.
  • U-shackle security:  Heat-treated specifically to create balance between hardness (cutting resistance) and toughness (for tensile and impact resistance).
  • Mount Bracket:  Colour matched mounting bracket for your bike. It has a user-friendly ratchet mechanism with an extra-wide, tough, rubberised fabric strap suitable for secure frame-mounting. The attachment strap is wound internally via the use of an allen key. This keeps your bike tidy by omitting any stray, loose ends.

  • Please note that replacement keys can be obtained from Knog at a cost of $20 for 1 key and $25 for 2 keys plus postage and handling. Due to high manufacturing costs we can no longer offer the first key free.

  • Accreditations: Our Strongman U-Locks have been tested and certified by renowned European Agencies for reliability performance.
