By combining Hiplok's reliable bike lock tech, a clever wearable design, and high-visibility reflective details, the Superbright Wearable Hardened Steel Chain Lock keeps both our bike and us safe on every commute. This lock comes in three styles, varying in weight and size. They're made with hardened steel for reliable durability and come with a reflective sleeve that protects the chain from the elements and keeps us visible to drivers on low-light rides.
