Kryptonite GK999492 Fahgettaboudit Lock, Black/Yellow, (1410) 14mm x 60"

Great product. Heavy, reliable. Likely very difficult for a thief to get through. Note, too heavy to bring on a cycle with you. But good to say, leave one at work or in a bike shed. Pricey though.

I have recently purchased this chain & lock and as soon as i took it out of the box i felt as if i got the right one.It is heavy, solid & easy to lock, unlock. The chain looks treated and Stands out as a serious deterrent.The key has a nice bright blue light that helps in unlit areas at night.Now i thought about maybe giving 3-4 stars but i concluded that the lock itself imo is definitely worth 5 stars so i have given 5 stars.The reason why I considered 3-5 stars is because I ordered this item from koo bikes and it took so long to arrive i contemplated sending it back.It had passed the cut off delivery date. Totally unacceptable. I was very annoyed.So my advice is if you want a solid chain and lock to keep your bike safe, I recommend this one.As for ordering it from koo bikes, fahgettaboudit.

Big strong chain n lock. Hopefully not have to rely on it to protect my belongings.

Heavy duty chain and lock

You are in a forest, you're walking with some random people, and a bear runs at you out of nowhere. You can't outrun it.You don't need to outrun the bear, just the next slowest person.You will never get a lock that is 100% protection, but if it makes the thief pick another bike with a less serious lock then it did it's job.This chain is the canine's cojones. The lock, not as much. In fact, I would consider it the weakpoint, if there was one. Not much of one though cause together they are a beast of a security system, but if someone has a grinder then they're going for the lock itself.Note: combined, the are heavy. Like properly "change the bike's dynamics if you have it wrapped round the seat-post" heavy.If you have an electric bike like me, then that is not a problem 😁The added Anti-theft offer from Kryptonite is a nice thought that makes me feel warm and fuzzy inside..... Don't know if I'll need it, or whether it'll pay out, but I registered and paid £20-odd for five years of it anyway. You never know 😶

I bought this chain from a Warehouse-Deal - good Price. I bought this since the Disc lock has the colours of the ''Fahgetaboutit'' Series suggesting the maximum security you can get plus is rated within the Kryptonite Security levels as a clear 10. Unfortunately the lock had a few niggles accepting the key and I decided to open the lock and see if I could adjust it.Surprise: this mini d-lock is in fact only a Series 4 lock, being rated by Kryptonite a 7-8.....Now the chain you can be sure is max. = it is a brute, so no questions there - Level 10. But the rule is: a chain is only as strong as it's weakest link... in this case the disc lock itself which is only a Series 4 level , 8-7! So the whole combo has to be sold as that , not ''Fahgetaboutit Level 10, only Level 8)! Looking at which of the mini d-locks of Kryptonite are really level 10 you soon will find the Kryptonite New York LIBERTY lock with a level 10. Looks same... Difference : different weight resulting from the insides not being identical. The heavier body ( ''Liberty'') is round and consists of 2 hardened steel tubes inside each other making it a real ''brute''. The Series 4 is ( or here ''New York '' - Lock ) is although sold as level 10 only a level 8 since it has only 1oval hardened steel tube - a very thick hardened steel layer - don't get me wrong, but it is in no way as chunky as the ''big brother''. The only thing they did do was put a ''Wolf's coat on a Sheep''... by adapting the colours and selling it for what it is not.It is a shame, I and my family are really happy with the 5 other Kryptonite products . I am not unhappy with this - it is just not right do sell something in this way. But I will not trust this little disc lock a main lock but only use it as 2nd or third lock - for that it is splendid. Thankfully I paid a very good price for this and really only need the chain, the lock had no priority in my case. The chain will partner with my real U=lock mini ''Fahgetaboutit'' with the 18mm shackle as main security. That is really a level 10.

Great lock, very heavy though at almost 5kg, but attached to an e-bike you won’t notice the extra weight. The chain looks like many opportunist thieves would avoid bothering to cut it. If they try I’m sure they will be there a very long time. BUY IT 👍

Fantastic, sturdy, great qualityNot had an attempted breach of the chain, but it is very heavy and inspired confidence that the item locked up will be secure.
