How does everyone store their bike locks while riding? The old kryptonite U-lock (just exchanged it for the current kryptolock atb) I had used a slide in frame mount that wasn't bad at all. Made a little noise but worked fine. This new mount they have is completely unmountable due to how much space it wastes and I'm a bit leery of the strength of the design... I currently don't have a rack and would like to be able to ride w/o a backpack for short runs so a on bike mounting solution would be nice! Am I doomed to the velcro type mounts or carrying a backpack?
