I just found the The "Cycle Club Junior" at my local Big Lots store for 6 dollars. I bought one on impulse and tried it out. I'm going back today and try for a second one. I foresee a need for making a two link chain out of these. A sticker on the package will inform you that all special offers and warranties are null and void. I'm still going to try for the second one. These are heavy and that's a good thing when it's a bike lock. I found this in the "hardware" department aisle. Did I mention they are heavy? This is a closeout, liquidation opportunity, short lived for those needing security hardware.
