Kryptonite 4 or oxford magnum?
Similar price, both gold secure... What is better?

The impression I got from reading reviews is that the kryptonite locks are better quality. The Oxford magnum has a slightly thicker shackle though.

It is not recommended to have a shackle longer than you would normally need because if you leave a gap thieves can insert a bottle jack or scaffold pole in to snap the shackle. Also there's the extra weight to consider, and whether the lock will fit inside your bike frame for transit.

If I'd needed a long shackle lock, then of the two I'd probably go for the oxford offer (I believe it is broader too,which may be useful if you have fat tires), but as I only needed a standard length one, I would have ordered the Kryptonite, had I not picked up a New York going very cheap.

However if you live near the shop selling the new gold rated Onguard Brute 8001 which appears to be much improved on their previous models, and can avoid the £7 postage, I'd suggest taking a look at that instead (see for the specs). make sure they sell you the new model, and not the old silver and black brute 5001.

There's a review of several locks here, including the Kryptonite:-
I looked at a lot of reviews before ordering a Kryptonite, and most of the d-locks I looked at had some complaints about snapped keys. The locks that had the most complaints about snapped keys also seemed to have the most complaints about rusting.

The best advice seems to be to keep the mechanism well oiled with wd40, or your preferred rust inhibiting oil, and to make sure the key is fully inserted with disc-lock type keys.

One reason I liked the new Onguard 8001 is that they've switched to a stiffer 'z' key for the new model, which is a stepped flat key with the pin cuts on the inside edges, so deep cut codes don't weaken the key, somewhat similar to the key Vauxhall used to use.

Watch out for the Key on this:

I was thinking of getting one awhile back but after reading the reviews I went with the Squire Urban Paramount D Lock, no issues with the key and have had it over a year.

Most D lock reviews have people moaning about about crap keys snapping/getting stuck and that, but in reality it is Human Error through not putting their key in the lock properly and also not spraying a bit of Wd40/GT85 in the lock every now and then.
