Thank you folks!

So chains can be better.

The bike is probably worth 600 give or take, new. It was bought from Costco, it isn't an elite one or anything, but losing it would be very bad for me. I reside in the suburbs of Waterbury, CT, USA. There is indeed some crime in Waterbury, it is one of those American cities that has fallen since the shift of industry overseas, it was a very industrial town when I was a boy (I am in my 50's).

I was under the impression that the U locks were easily defeated with car jacks or liquid nitrogen.

I think as money comes, I will get a ulock and a chain and padlock then. I will check out those brands. What online dealers do you recommend?
