Hi, I want something to lock my bike down. It can't be anything fancy since I'm renting, but I stand the bike next to a stout steel pole supporting the car-port (yeah, no garage unfortunately). So I'm thinking chain or cable. I had a wander through Bunnings and saw some thick (10mm) steel chain, but the fact that you buy it by the metre and cut it then and there with bolt cutters implies that it wouldn't be any harder for a thief to make off with my bike What about chains specifically made for security though, that boast "hardened manganese alloy" and "square links" and stuff. In practice, beyond the marketing, how much more secure are these? And what about security cables? Specifically I'm looking at the Python brand. It's 10mm braided steel cable. However, it I would guess that a cable would be even easier to cut than an ordinary 10mm steel chain. The portability is attractive though... What do you think? I definitely want something solid rather than an alarm, since I'm often nowhere near my bike. Overall I think the risk of theft here is low, but I'd like to take the precaution. Cheers!
