A great lock/chain combo, but some considerations first...
First, this is a great disk lock, well worth a 5 star rating, solid, secure feeling, and the alarm is definitely enough to get attention. Second, the chain is HEAVY, the cloth cover is a great plus to protect the bike where there is contact, and definitely promises to keep the bike secure in many different scenarios.

Now the considerations and why we gave this combo unit 3 stars due to the fitment, we have the constant need to have both our bikes secured, and chaining them together seems to be a great option, especially with a screaming alarm to accompany the chain. However, this puts more restrictions on the flexibility of the lock and it turned into a no-go for us.

The chain fits through both front wheels well, plenty of room to manage it through. Installing it with the disk lock proved to be the deal-breaker. The weight of both items would result in always settling the lock down after placing the lock and removing the key, which now set of the armed lock. Hurry fast to unlock it before the alarm initiated, and back to trying to find a location where the lock/chain would not drop, setting off the alarm. When we DID find a location, we were still stymied by the angle which we had to remove the key. It was now too close to the tire and the ground to remove easily, and would again trigger the alarm.

The key hole, being on the back end, made this a difficult application. It would have been a non-issue had the key hole been on the side. As it was, it became too time-consuming to think of going through this process every time we needed to lock the bikes.

Thanks to Revzilla's return process, we returned the item, and for now bought a simpler Kryptonite Hardwire they offered to lock both bikes together. We'll take a little more time to investigate a disk alarm, but are still leaning towards one of the smaller ABUS units.

Get the disc lock; you may not need the chain
You know, if a thief can defeat the disc lock then I'm not certain the chain will be of any use. In other words, I think you might be just as well off getting the disc lock alone without the chain. You see, the chain attaches to the disc lock and if the disc can be opened then the chain is of no use.

This disc lock will not fit on the rear disc of a 2016 Triumph Tiger XCx. The disc lock does fit on the front discs of my Tiger.

If you're concerned about somebody lifting your bike into a truck and carrying it off I suppose then the chain if secured to an anchor will prevent that, but unless you've got the bike anchored to something I'm not convinced you really need the chain.

Another thing is that it is a real hassle to get the chain on the disc lock and get the disc lock locked before the alarm starts going off and you have to start all over again.

I'm going to keep using the disc lock on the front, and I'm going to get a U lock of some sort and use the chain and a U lock to connect the frame to an anchor/post, or whatever I can.

Yeah, I think the disc lock alone is pretty good, some people think it's not a shrilling alarm; well, it's enough of an alarm to annoy anyone trying to mess with it, and I really don't know if it can be easily defeated. I haven't heard of one that was.

Versatile and strong
I live in NYC and keep my bikes parked in a secure garage. When I park on the street, I always use the disc lock. If it's for longer than a quick stop, I use the additional chain to lock it down to a fixed object. I feel secure knowing this lock is on the bike.

For the record, I've used other locks and have had one bike stolen and one attempted theft. This lock is a deterrent and I prefer to have thieves move on because this lock is a pain to break and will also draw attention with the alarm.

I use the disc lock all the time
This is a great disc lock. It's very easy to put on when the technique shown in the video is used. I put my orange warning cable on the inside of the lock before putting it on the disc, thereby keeping it secured while fastening the lock.

The salesman wasn't sure if the chain could be used with the lock affixed to the disc. It can, but it takes some practice and coordination to get it right. The chain can also be used with the lock as a standalone lock, putting it around a solid fixed object. If it's disturbed, the alarm will sound, attracting attention. Using it on the disc gives an extra level of security. I loop the chain through my wheel and then around the fixed object, usually some sort of pole, by passing the chain through the round link. The round link goes into the body of the lock, activating the alarm function. Then the "claw" end of the chain is attached to the arm of the lock.

I use the disc lock by itself for quick trips away from the bike. For longer times away from the bike, I use both the disc lock and the chain. A lighter chain would be easier to carry around, but then it would not provide this level of security. I keep my chain in a padded case (with my tools) in a hard saddle bag that's always on the bike, so it's not a big deal.

I realize that good locks keep the honest people honest. But the harder you make it for the DIShonest, the better chance there is, that they'll just go elsewhere and look for an easier target.

Good security, not loud
The alarm is underwhelming but the lock and chain are fantastic. The alarm will make people think twice or at least make it obvious that the thief is not supposed to be near your bike.

Nice alarm and chain
The alarm is loud enough to hear from the 3rd floor in my house and it doesn't go off randomly because of a gust of wind or anything. Only thing is I wish that I got a longe chain. Otherwise it does it's job and it does it well

Lots of options
Bought this lock and chain and have been using it for some time. What I really like about this lock and chain is not only the quality, but the fact that it offers you a range of options: you can use just the disc lock (armed or unarmed [just remove the batteries]) for when you don't want the weight of a chain or the disc lock with the loop hole chain when you feel the need (armed or unarmed). Gives you four options - and I really like having that flexibility. The alarm is sufficiently loud. I bought the yellow disc lock to 1) make it obvious to would be thieves 2) make it obvious to me so I don't inadvertantly ride off with it on my disc.
