So I have read in many places that thieves can quickly (10 seconds) ship through a cable lock. I kinda accepted this but thought that perhaps the speed was exaggerated (like when a contractor says he will finish a project). Well, I was volunteering at our local Co-op this past weekend and had the opportunity to help a guy tune up an old bike that his brother gave him. It had a 10mm cable lock wound around the top tube - useless because the combination had been forgotten. I figured I'd give it a go and grabbed a set of cable cutters. Wow, I don't think it took me even 10 seconds! Just took quick little bites and that was it.
