ABUSGranit XPlus 540 U-Lock + USH Bracket - Bicycle Lock with 13 mm Thick Shackle and XPlus Cylinder - ABUS Security Level 15

I really recommend it to everyone that really cares about his own bike.I previous bicycle has been stolen even if I had a gold secure label locker. With this locker, that is diamond label, I’m more confident to park the bike outside. So far so good with this locker.

PRO Package delivered on time.CON Package left on ground outside door when delivered. No call. Not sure how delivery got through back gate, or it was thrown over. Instruction was to leave with neighbour if I could not be contacted. No attempt made to reach me and I was present.PRO No visible damage to package or contents after said deliveryCON Part of the UHS mounting bracket was missing from the package contents in a small sealed bag. See attached image for missing part. Therefore cannot attach lock to bike until this is resolved. Will not use the lock until everything is in order. Dissapointed by this as I had high hopes for an Abus lock at this significant price point. Not a good first impression on quality control. Hardly what you want with a security item is it? Feeling "this is flaky". Tut tut. Sort that QA control sharpish ABUS!!!CON Only support available is to email Abus in Germany. I will update this in coming days to relate my experience. Otherwise it will have to be returned. EIther for a complete replacement, or a refund from Amazon. If my customer support experience is poor, it will be a refund.First impression of the locking process, the key and mechanism seem "awkward" and it isnt a smooth action. It seems to catch and has to be "jiggled" to get it to lock. There may be a technique to this that will be discovered over time or by actual real world use. Its not something I would want to have to deal with everytime I locked this unit. That would be very frustrating and not acceptable for this anount of money. But I need the complete UHS bracket first before I use this item in earnest, or it gets returned.Otherwise the lock presents itself as sturdy and as expected.At this stage can only give a three star due to initial doubt surrounding QA, missing part and "stiff, awkward" locking action. That may change in due course when immediate concerns get addressed.Pity really.

A great D lock, a bit different to fit in the bracket, especially if one is used to the kryptonite ones.It might take a while to get used to put it back on the bracket, but the quality is really good, not too heavy.Bought it after doing lots of research and after considering that with the right tool, pretty much everything can be opened (at least in a city such as London)

A very solid and durable product, I recommend it to anyone who is looking for something decent to secure their bike.

NB: This comes with the USH bracket, rather than the smaller, slicker and more convenient Eazy KF bracket. To use the Eazy KF bracket, you'll need to order "Abus 9210 Shackle Clamp" and Eazy KF bracket. To fit the clamp onto the lock, trim away some of the rubber coating on the U shackle. The Eazy KF bracket allows you to clip the lock onto the frame and press a button to release, whereas the USH bracket requires you to unlock the lock to remove.The lock seems solid and the mechanism works well. This is the shorter 230mm version, a longer 300mm version is also available. You do need to turn the key to lock rather than the D section clipping in. Lightweight for the security rating which is Art Level 3 and Sold Secure Gold. At around 1.5kgs it is half a kilo less than the Kryptonite equivalent.One star off for value for money. At £70 it is expensive, but if your bike is worth it, you can't get much better for the weight. Please press the 'Helpful' button if this review is useful for you!

I've been using this for my hybrid bike basically leaving it for about a few hours at a time for college. The lock is pretty beefy and is in fact beefier than some of the bike racks I've used. It is pretty thick and is reasonably lightweight for the protection it provides. It is even recommended by well renowned lock pickers on Youtube, such as Lockpickinglawyer, as it has a very secure locking mechanism. The shackle's rectangular design makes it hard for boltcutters to hold onto. I also chose this lock because it seems to withstand a lot of force before you can break it with a jack. I use this lock alongside a cable to secure the front wheels and a rotor brake lock. Sometimes I even use another U lock with it if I'm going to leave it for longer. The USH bracket has been really helpful in carrying it around especially if you don't want to carry it on a backpack as I do because it hurts my back after a while.So far, I haven't found any cons to using this lock. Keep in mind that locks are only a deterrent. A determined bike thief would get through any lock. Although it is not on the affordable price bracket for locks, it is surely a worthy investment if you want to keep your bike.

Please improve the instructions to atach the lock to a bike frame, and improve the atachment also, once it was done I could see how easy it was, you could do it with your eyes closed, but for someone that never done it before or even owened a bike lock it was harder than what it needed to be, lock also needs to be thicker.When the lock has a better atachment and a thicker metal I'll give it 5 stars, for now 4 is enough.EDIT - the lock mount is even worse than I thought, the lock doesnt stay fixed but moves a little bit side to side when is bumpy roads causing the lock to hit my spokes, not only that but the lick also doesn't "click" I'm place so when I put my bike upside down to fix my spokes the lock fell from the atachment hitting my frame and scratching it, no problem for a cheap bike but for a bike that costs around 2k it's a big blow, thanks for making amazing locks ABUS but Go F. Y. with that stupid atachment, surely something less cheap would be more appropriate for such a high end product, thanks for damaging my wheel and my frame/paint job.
