8/10 Security rating | Kryptonite Anti Left Protection - Up to $3,000.  The Evolution 1090 Integrated Chain is our first choice in protection when it comes to locking up and keeping your bike safe. This chain features a high security disc-style cylinder that resists picking and drilling.  Kryptonite  offers an Anti-Theft Protection Offer (ATPO) a program that reimburses registered customers for a specific monetary amount in the event their bicycle/motorcycle is stolen due to the opening or breaking of the lock by force. ATPO coverage is not bicycle insurance and there is no affiliation with an insurance company. The offer is administered by Kryptonite. To locate the ATPO coverage amount, look for the sticker on the front of your Kryptonite lock package or check the product page on the Kryptonite website. This is an optional offer and you must register to participate in the Program. ° Product dimensions: 35.5” (90cm) chain length° Product weight: 6.10 lbs (2.77 kgs)° 10mm six-sided chain links made from 3T MANGANESE STEEL° Patent-pending END LINK DESIGN secures chain to hardened deadbolt eliminating critical vulnerability° HIGH SECURITY DISC-STYLE CYLINDER is pick and drill resistant° Patented*, reinforced OVAL CROSSBAR LOCK HEAD° SLIDING DUSTCOVER protects and extends cylinder life° 3 STAINLESS STEEL KEYS – one LED lighted key with replaceable battery and 2 new, ergonomic ‘I” keys° Durable WEATHER-RESISTANT nylon sleeve prevents scratches° Key Safe Program
