The HEXBAND lock is OTTOLOCK’s strongest quick-stop bike lock. It utilizes the same patent-pending band design as the original, but uses 6 layers of stainless steel wrapped in an ultra tough Kevlar jacket for even more resistance to shearing tools and cable cutters. Under load, the bands slide upon one another to effectively reduce shear forces. Designed for quick stops and protecting against opportunity theft, the OTTOLOCK HEXBAND cinch lock is ideal for cyclists and other outdoor enthusiasts who value their gear and want a small, safe, and lightweight solution for their active lifestyle. It's simple and versatile, but surprisingly stronger than meets the eye! For maximum security, use a redundant locking method with both a U-Lock and a cinch lock.
