The Kryptonite New York Fahgettaboudit Chain and New York Disc Lock consists of a 5-foot chain of 14 mm 3t hardened manganese steel with a nylon sleeve. A 15 mm steel shackle disc lock, coated in PVC, secures the chain. At full price, this lock will run you $178.45.
The Fahgettaboudit chain provides enough length and flexibility to lock up both wheels with the frame without needing to remove the front one.
This lock is a serious theft deterrent. Just looking at it is intimidating. The independent lock rating agency Sold Secure gave it their highest rating, "Gold," for bicycles and motorcycles. It also receives a score of Category 3 from Thatcham Quality Assured, a motor insurers' automotive research center in the UK. Kryptonite themselves gave it a perfect 10/10 security score, unmatched by any other lock reviewed. On paper and in hand, it's a beast.
Power tools are necessary to break this lock.
In our lab of destruction, this lock fared at the top of the heap. Hand tools were useless against this big guy, and it took roughly 45 seconds for us to get through the hardened steel to cut the lock. After one cut, this lock opened up 1/2 an inch. If you lock up responsibly, this means it takes two cuts of an angle grinder to compromise the Fahgettaboudit Chain and Disc Lock. If that doesn't convince you of this model's security, Kryptonite offers a generous theft protection program with the purchase of this lock. If this is important to you, be sure to register as soon as you buy this lock.
This lock needs one cut and plenty of hammering or two cuts to be removed from most bike racks.
Ease of Transport
The Kryptonite New York Fahgettaboudit Chain and New York Disc Lock is as cumbersome to carry as it is to say. It's not made to toss in your backpack and go. This lock is intended to stay where it lies, either at the bike rack outside the office or the one outside your apartment building. For testing sake, we rode around town with this model in our backpacks, and we felt all 15+ lbs of it. Uff da. Compare that to the 5.3 oz of the Ottolock Cinch.
Our testers tried various methods of transporting this monstrous chain lock, but we didn't like any of them.
If you must ride with this lock in tow, our best solution was to wrap it around the handlebars. This puts a lot of weight on the front wheel and slows you down, but if you need to move it a few miles, this is the best way to carry it (unless you have a basket or panniers installed on your bike). We would not be thrilled to ride over five miles with it attached in this manner, though, and do not recommend transporting the lock habitually. The easiest high-security model to carry is the ABUS Granit X-Plus 540, which weighs less than three and a half pounds and mounts on the frame.
It's possible to transport this lock, but it seriously affects the handling and increases the weight.
Ease of Use
Due to its size and heft, this is the toughest and slowest lock in our review to use. You need to be careful to avoid chipping the paint off your bike as you feed the chain around your frame. Carelessness might even result in a dent to the frame, and we were sure to avoid the chain resting entirely on thin spokes when locking it up. Our testers appreciated that top-shelf security means heavy-duty materials, but we were often frustrated when using this lock.
The significant weight of this lock makes securing it a cumbersome chore.
The Fahgettaboudit Chain and Disc Lock comes with three keys, which is handy, and one of them has an integrated HID light. Kryptonite includes this lock in their Key Safe Program, which means you're eligible for a one-time, free of charge replacement pair of keys over the lifespan of your lock. We dig that.
Use the sliding dust cover to prolong the integrity of the locking mechanism.
The chain of this lock is five feet long, which is long enough to snake through both wheels and the frame without having to remove anything. Due to its thickness, we couldn't fit it through any saddle stays or use it to lock up our panniers. This heavy chain is useful beyond bikes, though. We used it to lock up dirt bikes outside a watering hole and to secure items in our garage overnight.
The two chain locks selected and reviewed by our experts. The Hiplok is on the left, featuring 8 mm thick links. The Fahgettaboudit Chain is on the right, consisting of thicker 14 mm links.
The Fahgettaboudit Chain and Disc Lock is best used for overnight parking or extended daytime parking. It's all but imperative to use the same bike rack on a regular basis so as to leave the lock secured around the rack until you're back with your bike.
This lock is beefy and intimidating in ways this reviewer only dreams for himself.
This lock costs $178.45, more than any other model reviewed. It's a lot to pay for a bike lock. That said, it's beastly nature might bring you peace of mind, which is invaluable. In our opinion, this model doesn't present much value unless you need a deterrent of its size.
Transporting this lock is a true pain, but it offers the best combination of security and versatility for folks who don't need to move it around the city.
The Kryptonite New York Fahgettaboudit Chain and New York Disc Lock isn't for the faint of heart. It's about as burly as locks get. It isn't practical for running errands or moving from point A to B to C. It's best sticking to point A. If you need a high-security lock that stays in one place, this is your best bet. Lift with your legs, not your back…
