##Kryptonite New York Standard Nyl Lock & Flexframe Bracket Sold Secure Gold If you're looking for maximum security for your bicycle, look no further than the Kryptonite New York Standard Nyl Lock. With a Flexframe Bracket included, it can be easily fixed to your frame for maximum convenience. Based on a super-tough 16mm hardened steel shackle, this premium u-lock takes advantage of a hardened deadbolt design which gives even more protection to twist-type attacks. The disc-style cylinder is pick and drill resistant while featuring a dust-cover that protects it from the elements. Supplied with three stainless steel keys, one of which features a useful LED light for unlocking your bike in the dark. The key safe programme means you can easily get keys replaced should you lose them, too. Kryptonite is so confident in this lock's performance that they offer an optional Anti Theft Protection Offer that provides cover of up to £2500 for bikes should they be stolen due to the opening or breaking of the lock by force. With a gold certification from Sold Secure, an independent UK based bike lock testing standard, you can be sure of the highest level of security for your bike.
