Can you get one end link through the other, like tab A/slot B style where you could put the lock through just the one link and have it be locked? You can't on the newer ones. Also, are the links 6 sided or 4 sided?

I have one of the current ones (allegedly 3'3"), and I can get it around a bike rack or other small pole, through one wheel, and then put the two ends on the shackle of the micro-U lock and lock the other wheel's rim/tire inside the shackle as well. Not enough chain to do it just as a regular loop, and it's not going around a thick pole like that.
