I did not have a lot of spare cash when I went searching for a bike lock. I ended up at a local industrial rigging supply shop amd I purchased 2 feet of the strongest hardened chain they had. It took the guy some work with a diamond bladed chop saw to cut it. That made me feel good , considering most thieves wont be carrying that around. I use a hardened heavy duty padlock to secure the chain. So far this has worked well. I admit I keep my bike in sight at all times regardless. If I were to actually leave it unseen for any time I would currently use the chain, my kyrptonite chain lock, and my cable lock through the wheels and seat. But this is unlikely.
