RockyMounts Hooligan Chain Lock Black, One Size

When you know what to expect where you're going, make sure to throw the RockyMounts Hooligan Chain Lock over your shoulder before hopping on the bike. Its 40-inch length and 7mm diameter allow you to lock up the frame and either front or rear wheel, and the dimple key and cylinder design is simple and easy to use. The hardened, heavy-duty chain is covered in a nylon sheath that's sewn all the way to each head, and the heads are wrapped in silicone to prevent damage to your bike.
