Bike lock chain. This Kryptonite bicycle lock is built to Sold Secure Gold Standard. This means that is has been manufactured to withstand a 5 minute attack. That's impressive when you consider that some locks can be overcome in 5 seconds. "Integrated" means that the Evolution lock barrel and chain are one, not separate.
- The chain is constructed with 10mm-thick hardened triple-heat-treated boron manganese steel 6-sided links.
- The chain boasts a patent-pending pin-less design where the chain is secured to a hardened deadbolt to ensure maximum holding power to ward off attacks.
- The chain is fully enclosed in a nylon-webbing sleeve to protect your frame's paint job from scratches.
- The nylon cover also makes the chain easier to coil and easier to transport.
- Supplied with 3 stainless steel keys.
