Locks that work

**I wouldn't bother with the onguard, only 14mm shackle. The abus is the better choice.

But I would stretch your budget and get lock everyone raves about, kryptonite Fahgettaboudit.

First, you should know the exact technicalities, OnGuard Brute Mini vs Abus U-Mini 40 no doubt OnGuard(much heavier) is much more robust and stronger U-Lock.It looks like the comparison between, Mirko CroCop Filipovic(OnGuard Brute Mini) vs Randy Couture (Abus U-Mini 40) in clasic kickboxing mach.:)

• Abus U-Mini 40, 14mm shackle

• OnGuard Brute Mini, 16.8mm shackle
