ChainKASE X-TREME Chain Lock, 1219mm x 8mm

The BiKase ChainKASE X-TREME Chain Lock is built for cyclists who want a serious deterrent that still routes easily through frames, wheels, and fixed objects. Its 1219mm (48 in) length provides the reach needed for real-world locking setups, while the 8mm hexagonal hardened steel chain targets resistance to cutting and prying in high-risk parking situations.

• 8mm hexagonal hardened steel chain - tough link shape and hardened construction designed to better resist cutting attempts than basic round-link chains
• Titanium-reinforced build - added reinforcement intended to increase overall durability for frequent use and higher-theft environments
• Dual-bolt locking mechanism - secures to both sides of the lock body to improve pull resistance versus single-sided designs
• Resilient chain cover + protective lock coating - helps reduce frame scratches and adds an extra layer of protection against daily wear
• Includes 3 laser-cut keys - convenient spares for commuters, households, or keeping a backup key stored separately
