Enter the Kryptonite New York 1210, a high-security lock with an innovative oval crossbar disc build designed to defeat thieves' toughest attacks. The New York 1210 is equipped with a 12mm, six-sided chain made of 3t hardened manganese steel for maximum strength. The chain is tough and intimidating, with a durable protective nylon cover that includes hook 'n' loop fasteners to hold it in place. The New York 1210 also includes the Evolution Series 4 disc lock and 14mm Max-Performance steel shackle. The lock's high-security disc-style cylinder--which offers more than one million key variations--boasts a patented, oval-hardened steel crossbar for extra security. The New York 1210 offers such additional security-enhancing features as hardened double-deadbolt locking for extensive holding power, a reinforced anti-drill/pull cylinder protection system, a sliding dust cover that protects and extends the cylinder life, and three keys--one of them lit with a high-intensity bulb and replaceable battery. Ideal for anyone who lives in moderately high crime areas, the New York 1210 boasts a 10 ranking on the Kryptonite 1-12 comparison system, which ranks the varying levels of security within the company's product range. A lock that ranks 1 on the Kryptonite scale might work if you live in the burbs and have a Rottweiler parked next to your bike or motorcycle. However, city dwellers demand extreme protection, which is why the New York LS is built for serious deterrent security. The Legendary Durability of Kryptonite Locks The first big test for Kryptonite locks came in 1972, when Kryptonite founder Michael Zane directed the Second Avenue Bicycle Shop in New York City to lock a three-speed bicycle to a signpost in Greenwich Village. Although thieves immediately stripped all of the bicycle's removable parts, the bicycle itself remained for 30 days and 30 nights. The Kryptonite lock and the bike frame were still in place, even though the lock had been attacked numerous times. The publicity gave Kryptonite the boost it needed and forever changed the face of bicycle security. Twenty-two years later, Kryptonite returned to the streets of the Big Apple to test its latest innovation, the New York lock. In April 1994, the New York Post laid down the ultimate challenge: Could Kryptonite's New York lock last 48 hours on the toughest streets of New York? In a city where more than 100,000 bikes are stolen each year, Kryptonite and the Post locked a brand-new, bright green Univega road bike worth $600 to a parking meter in the East Village--the Bermuda Triangle of New York bicycle thievery. For a full 48 hours, the bike remained locked on the corner of Avenue A and 11th Street. Zane and Neil McDaid, director of product development and design for Kryptonite, watched from around the corner as the bike came under every possible means of assault, stumping thieves at every turn. After 48 hours the bike remained intact except for the gear derailleur, which had been stripped off. The lock showed definite signs of abuse, but it had not failed. The New York lock had met the Post's challenge. Not satisfied with the length of the test, Zane moved the bike to SoHo for another six days and, finally, uptown near the Lincoln Center. Even in these high-theft areas the properly locked bike lasted another three weeks before being pulled off the streets by Zane and McDaid. The Post also ran the New York lock through a battery of street tests using common bike theft tools: a 4-foot bolt cutter, a crowbar, and a hammer. The non-Kryptonite locks cracked in seconds, but all methods failed on the New York lock, even the monstrous bolt cutter, which was rendered useless with large dents in its jaws. About Kryptonite In the early 1970s, Michael Zane was a free-spirited, bearded kid with a VW van and a big idea for a new kind of lock. He traveled thousands of miles showing the unique U-shaped locking device and spreading his passion for bicycle security to bike dealers all around the country and forged lifetime relationships. The company soon expanded its product line to include power sports, hardware, and snow sports security. Through innovative product designs, cutting-edge marketing savvy, legendary customer service, and pure fanaticism for security, Kryptonite grew with a cult-like following. In 2001, the company that was started in a VW van was purchased by industry giant Ingersoll Rand and became a flagship brand in the company's Security Technologies sector. Publications such as Bicycling, Fortune, The Wall Street Journal, US News World Report, and a host of others continued to tout Kryptonite products as the best on the market. The company's dedication to its customers is best represented by its actions during the fall of 2004, when it was discovered that the industry-standard tubular cylinder could be compromised, at times, with a household item. Kryptonite flew into action, created a voluntary lock exchange program, and replaced more than 400,000 locks in 21 countries for free. In essence, the company redesigned the equivalent of nine years worth of new products in just 10 short months. Kryptonite is the only company in the world that offered such a comprehensive plan to customers, taking its "legendary customer service" pledge to new heights.
