For my Bakfiets I've got some Abus city chain thingy that weighs about 2 kg and is gold rated; think it was about £100 a couple of years ago. If I were looking now I'd go to Pragmasis and get a suitable chain and lock.
That's what I thought, and have read positive things about them as well as helpful advice from them in this forum. I am however put off by the lack of a response to my questions sent to them.
Yeah kinda figure if they got in to the garage it's game over anyway.
Are there gold secure chains?
