Have been to Halfords and rattled their D Locks and they all made a noise. Bike Hut and Kryptonite Evolution.
Are there any quiet ones that come with an ingenious carrying  system for smaller frames?
Carry it in something that supports the D and the lock part? Twofish lockblocks, two on the bars one on the stem so there's nothing to rattle?
Some may be less rattly than others, but I don't believe there a way of carrying them on the bike (rather than on you or in a bag) that is completely rattle free.
My kryptonite has a rubber o ring that you can push up to stop the rattle, but guess what happens once it's vibrated a bit? The ring slips back slightly and it rattles!
I've given up trying to frame mount and stick it in a backpack.
Abus x plus granit. Years and thousands of commuting miles of trouble and noise free service. Mounted inside my frame with the included mount
Have an Evo as well, it's not too bad on the mount but does have a slight rattle that only strapping it to something will solve. Maybe make a frame bag for it?
