Thanks for that info.Hi ColonelSanders,
The set of lock (cable& padlock) you see in the picture is one that I bring on the road. The cable is a 6-feet Serfas brand less than 1cm thick, cost $15, nothing special really. It weighs around 380gr.
The padlock is a China made, cost around $12, again nothing special. 230 gr.
Some might think that I am so daring to bring such little security for my bike. But the fact is that bike theft in Singapore is not as rampant as in other big cities in US or other places. But still, low crime doesn't mean no crime. So at school, I have left another set (chain and padlock) so I can double up the security without carrying two sets of lock. At office, I normally lock the bike with just the cable and padlock to the railing outside my office door (still inside the building). At home, when I have to leave the bike outside I double up the security with a set of stronger chain and padlock (Stanley brand, laminated steel with shroud), recently bought by my wife as a 'gift' so I can leave the bike outside ^^". 590gram, so I never carried it around. hehe..
