New for 2018: Hiplok presents the Z-Lok Combo. The Z-Lok Combo is a reusable cable tie lock with a solid steel core. It is suitable for securing bicycles on bicycle racks but also for short "pit stops" during a tour. In contrast to the Z-Lok, the Z-Lok Combo is wider and has a three-digit combination lock. It also has a maximum diameter of 50 cm.
