Cables/Chains

This is it. The big boy of locks. Use Giant's SureLock Force 1 Chain Lock in the sketchiest areas to secure your prized possession. This beefy lock uses 10mm-thick titanium-enforced steel links with a hardened-steel double-locking shackle that provides maximum security. The high security, pick and drill-resistant lock cylinder uses a laser-cut key for the ultimate in protection. Encasing the chain is a water and heat-resistant cover that won't scratch your bike's finish.

Giant's SureLock Tough 1 lock incorporates the strength of a heavy-duty chain with the simplicity and portability of a coiled cable lock. Square steel chain links are tough as can be, and they're coated in a durable nylon cover that protects your bike's finish. The double bolt lock mechanism resists picks and drills so you can lock your bike up without worry.

Planet Bike's Quick Stop RS Resettable Lock is a great way to protect your two-wheeler. It boasts Planet Bike's impact-resistant, pick-proof, E-Z set combination lock (you can reset the combination anytime you want) and a plastic-covered 6-foot-long, 10mm-diameter cable that reaches around both wheels, the frame and an immovable object. This self-coiling lock is easy to carry, too.
