Is it normal that the Abus Bordo folding lock rattles? I have the latest Abus Bordo Granite X-Plus 6500 folding lock:



It is cased inside a rubberized pouch that attaches to one of the bottle-cage locations:



Very convenient, but sadly, it rattles while riding on an uneven surface, which can get quite annoying, and does not make for a smooth ride.



Firstly, is that normal, or is something wrong? (Has one of the bolts come looser than it should be?)

Secondly, how do I prevent this from happening?
This is a late answer I know, but I've found a solution to the rattling problem. I've had an Abus 6500 for nearly 3 years now and the rattling always annoyed me. I used to wrap a kind of nylon strap between the lock as I folded it and that partly solved it, although most of the rattle was coming from the joints themselves. It was only just today when I thought of this: I sprayed some chain oil, the type that comes in a spray can, into the joints, between the bars. As you may know, this oil is very liquid when sprayed but soon solidifies as the solvent evaporates. This allows it to get right into the joint and GREATLY reduce rattle. There is inevitably some that runs onto the parts you need to touch so a bit of cleaning up afterwards is necessary but the result for me is just astounding. I just wish I'd thought of it 3 years ago!
