The RockyMounts Hooligan Shorty Chain Lock is the lock you throw in your pack when you know what to expect where you're going. Its short length minimizes its weight without minimizing security, and provides just enough space for the rack you go to every day. 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.
