So let's talk locks and security

Unfortunately I'm a member of other internet fora, some involving motorised methods transports.

On these we also discuss security and usually have a definitive thread, on certain motorbike forums there are members who actively talk to thievies to learn how they work and inforrm the way they work so we can be better informed on how to defeat them.

I'd think you'd struggle to get the same level of involvement on this forum - lots of people with lots of stolen bikes in the past. Generally speaking, I don't think that there would be any room for discussion between us and bike thieves that wouldn't involve repeated D-locks (of various quality) to the face.

Additionally, bicycle thieves are of a different class than professional motorcycle thieves - average value of rice rocket £10-15k, HHSB £1k. They will be less sophisticated and more opportunistic, but that may be changing.

A list of chains d-locks sizes does give an answer to which ones are good and which are not worth the money. Unless they are all worth the money, which I know to be wrong as the oxford d lock is on that list.

I searched for a similar thread and the closest is Fox's but does give the information I'm looking for.

Well then, you have just stated an option. This forum is full of opinions. But there may not be a thread with all the answers on it. Do the research and contribute by starting one.
