    Can i use my own chain with a ulock mini?

    I've started locking my bike up in danger areas (i know, never a good idea but i can't stand the bus) of my city and I've decided that a onguard mini ulock and a kryptonite combo lock aren't enough. I need a chain.

    I have the opportunity to buy a thick chain for $20. Can i use the onguard mini to shackle it to my bike or do i need to buy one of the kryptonite locks specifically made for the chain? I don't see why I should pay $100+ for a chain if I already have two locks. Thanks for any info you all can provide!

    Are you buying the chain at a store? If so, how is the store cutting the chain and how long wil it take them? It will take a theif about the same amount of time.

    Hardness of a chain is as, if not more, important than thickness. Kryptonite an dother bike security chains are hardened.

    regular chains from hardware stores are easy to defeat.

    Any chain/lock can be defeated.

    If you are really worried, get multiple quality chains/locks and do what theifs don't like. Make it inconveinent. You don't have to take the chains home if you worry about weight. I used to ride to work, and leave the locks on the bar at work since I used them daily there.

    A quick way to tell if a chain is case hardened, drop it on concrete, a hardened chain rings bright cling-cling-cling, non-hardened chain a dull clunk-clunk-clunk.

    this is just a general rule, not an acid test of the chain's theft resistance.
