A happy compromise between a cable lock and a U-lock, the Abus Bordo uGrip Lite Mini 6055 Key Folding Lock is a mid-level security system for your bike. In lieu of rigidity, you get a compact lock that fits easily in your jersey pocket or hydration pack, or attaches to your frame in a secure, streamlined fashion. Its increased flexibility also gives you the advantage in less-conventional lock configurations without being quite as easy-to-cut as a cable, and its snap closure means you don't have to get your key out to lock it. Its steel core is covered by a synthetic coating to protect the paint on your frame, so you don't have to worry about chips or abrasions when locking up.
