Protect your bike from theft by using this OnGuard Pitbull U Lock. This combination lock and cable set only weighs 1.9 kilograms, making it easy to carry. With a thickness of 14mm, the shackle uses a Quattro Bolt mechanism, making it resistant to pulling and locking the shackle and crossbar from 4 different sides. The crossbar has a double coating to make it weatherproof. Open it with laser cut keys.
