Performance & Use Case
The Onguard Pitbull D-Lock delivers Sold Secure Diamond-rated protection in a slightly lighter format than the Brute. Built for medium to high-risk urban locking, the TriRadius shackle profile gives generous internal clearance for versatile locking around frame, rack and wheel together.

Construction & Security
The 14mm hardened steel TriRadius shackle resists cutting, prying and jacking. The X4P Quattro Bolt mechanism locks the shackle on four sides simultaneously. The Z-Cylinder is bump-proof and resists picking, pulling and drilling. Co-moulded crossbar cover and double-rubber-coated shackle protect the bike's paintwork. All-metal end caps add hit and drop protection. An automatic keyway cover seals lock internals against the elements.

Length & Format
Available in two shackle lengths: 230mm and 292mm. The 230mm secures bike to rack tightly; the 292mm adds clearance for awkward locking points or for two bikes together. 5 laser-cut keys ship with each lock, including one with an LED micro-light. All-tube mounting bracket included. Lifetime warranty.
