Kryptonite New York Fahgettaboudit Chain 1410 and Disc Lock

Kryptonite New York Fahgettaboudit Chain 1410 and Disc Lock is built for the riders and shops who need serious deterrence against organized bike theft, not just casual opportunists. The chain uses 14mm six-sided links forged from 3T hardened manganese steel, sized to resist bolt cutters and cordless grinders that make short work of thinner chains. At 3.25 feet (100cm) long and 10.8 pounds, it's heavy enough to loop through a frame and a fixed object in high-risk parking situations — garages, subway racks, overnight street parking — where a cable lock isn't a real deterrent.

The included New York Disc Lock backs up the chain with a 15mm max-performance steel shackle, a patented oval hardened steel crossbar, and a hardened double deadbolt that resists twisting and prying attacks. Its high-security disc-style cylinder has built-in anti-drill and anti-pull protection, along with a sliding dust cover that keeps grit and moisture out of the keyway over years of outdoor use. The whole system carries Kryptonite's top 10/10 security rating, and it ships with three stainless steel keys plus access to Kryptonite's Key Safe Program for replacements. A nylon cover with hook-and-loop fasteners protects paint and finish where the chain rests against the frame. This is a stationary, high-security setup rather than something to carry on a ride, built for anyone locking up in a place where theft risk is high and the bike is worth protecting.
