At 30 feet in length, the Kryptonite KryptoFlex 3010 Looped Cable comes in handy when you're riding with a large group and need to secure multiple bikes before heading into an establishment for a quick bite to eat. This looped steel cable requires you lock it with a traditional combination lock or U-lock before leaving your bikes outside. We'd recommend you don't leave your carbon superbike or full-suspension rig unattended for a lengthy duration with this looped cable, as it's more a theft deterrent for opportunistic thieves than a hardcore lock for city use and long duration stays, seeing it's only 10 millimeters thick. However, it does serve its intended purpose quite well, securing your urban commuters and bar bikes when you're grabbing libations and late night grub before heading home.
