Evolution Series 4 1055 Integrated Chain – 10 mm x 55 cm?

The Evolution Series 4 Integrated Chains are for convenient bicycle protection in moderate to high crime areas.

• The hardened triple heat-treated boron manganese steel chains include 10mm six-sided links.
• The integrated chains secure with a new patent-pending integrated Evolution series 4 lock head.
• This innovative series of chains also feature a patent-pending pin-less design which secures the chain to a hardened deadbolt and allows for no weak link in the chain due to extensive holding power of the link itself against attacks.
• Chains are enclosed in a nylon-webbing sleeve to protect paint from scratches and allow for easy portability and tight coiling during storage.
• Comes with 3 stainless steel keys including a lighted LED key with replaceable battery and 2 new, ergonomic ‘I’ keys.
• One key is lighted for easy access at night; replaceable battery insures that light can be used as long as the lock.
• The new ‘I’ keys make opening a disc-style cylinder much smoother.
• Approved to Gold Sold Secure standard.
