What is the best lock?

two ridiculously heavy locks, and all your component still unprotected.

I would say its not worth the weight of carrying a second quality mini-d as they are indeed ssssoo heavy. And when your using it just to attach your front wheel to your frame its even more silly.

One D lock preferably going through chain ring, and a simple cheapo detterrent cable going through wheel etc is better I think.

bars/stem can still come off , of course. But on my bikes I tend to modify the stem so its not easy to take off.

I'm buying myself time, not infinite, component can be easily be replaced, bike frame, wheels, etc. are not usually.

I carry the Evo Mini with me, I only carry the Fah when I need to lock it for a longer time, and Evo Mini's ridiculously heavy??? have you weight that thing? it's not even heavy compared to the Fah,
