locking the rear should be emphasized. fronts are much more replaceable.

Combining chain and u-lock seems to be a good idea, as they require different tools to cut. Most thieves won't carry both around.

skinny poles and tight non-aero track frames.

also, box rims and skinny tires.

also, not locking up outside for more than 30 seconds.

number one thing thieves rely on:

people thinking they can rely on thieves.

most theives will do exactly what you think most thieves won't do when you think they won't do it and that's how they stay thieves.

Depends on the rim and cutter.For example,a small cutter would easily cut a singlewall/lowprofile rim with the tire deflated but would't work as easy on a deepV because it doesn't open far enough.

Using multiple/different locks is not about wether the thief has the tools or not but rather about increasing the time it takes to defeat them.The longer it takes to defeat locks, the riskier the theft becomes.

it wouldnt be one bite, but it would work quite easily.

I concur completely with your statement. I do however, want to add that employing different types of locks can increase the time it takes to steal a bike as well as the possibility that it will be stolen.

What everyone should keep in mind is that no bike is completely safe. Every lock can be broken given the proper tool. The goal is just to make the theft as difficult as possible to deter the intrigue of theft.

You could just ride a clunker to the places you need to lock up your bike and take the nice one out when its leisure riding so you don't have to ride it and it'll always be with you.

My mini u lock, I lock my rear rim to on part of the triangle.

But now i have deeper rims, I can't So i moved over to big chain lock.

agreed. however using two different lock styles is definitely a plus. im pretty sure this has been said before many times, but bike locks only buy you time with bike thieves and if they see one u-locked and another u-locked and chained, they'll probably go for the easier one. or at least cutting the two locks will take longer and perhaps a pedestrian or someone else might notice.

The best locking strategy is to just use a u-lock and lock up next to a bike that is A) Nicer B) Easier to steal C) both. C + U-Lock equals best method.
