SDZ18 delivers enlarged working clearance, enabling locking frames‑plus‑wheels or anchoring complete bicycles onto thick railings and lampposts. Keyless resettable combination, alloy‑steel lock‑blades and frame‑mount bracket included. Designed for overseas B‑side buyers requiring wide‑span locking capability.
