OnGuard Mastiff Chain (180cm x 10mm/6 feet x 0.39 inch)

OnGuard's Mastiff Chain delivers major protection for your bike in high-risk areas. Its titanium-reinforced, 10mm hexagonal links resist attacks from saws and cutters. The burly lock holds up to picking, pulling, and bumping, and it locks on all four sides of the shackle. This lock comes with five keys, including one with a built-in light.
