lock-up techniques

so, ive been wondering. im thinking about getting a new lock, cos this chain thing ive got is getting to be a little too much of a hassle, and im thinking about a mini. how do you guys use these? ive seen stuff, like on sheldonbrown etc., that suggest ways of using a mini, and i know/have seen people who just lock their frames, or their rear wheel to the frame. is there a consensus as to the most effective way to use a mini-u?

If you have track ends, you can run tight enough tire clearance that a chain breaker or removal of the chainring is necessary to get the wheel off. That way you can concentrate on the front wheel.

Yeah, I accidentally did that one time. Kind of sucked when I got the first flat...

...only problem is said thief'll probably have unscrewed your axle bolts and yanked on your
wheel before they figure it out. I'd still lock the rear as more of a visual deterent.

That lock is gonna be a very heavy lock...it is the original NY lock with a shorter shackle, but will weigh almost as much. If someone is parking a $1,000 bike in Manhattan (for some insane reason) they might need a four pound lock. But, for people parking a $500 bike in "Friendly Village", a lighter mini-lock provides almost as much security, and is much easier to carry. Two such locks are the OnGuard Bulldog Mini and the Kryptonite Evolution Mini.

Put the Mini u-lock around the rear wheel a couple inches behind the seat tube. In bad areas, secure the front wheel with a cable lock or a second mini-lock. Your bike is not going anywhere.

Never, never, never, put a u-lock around the seat tube or any part of the frame. A dumb crook will attempt to use the frame of the bike as a lever to break the u-lock. He will pretzel your frame long before he breaks the u-lock. That is why the u-lock must enclose the rear wheel and ONLY the rear wheel. If a crook attacks your bike, he will fail. He may damage your rear rim...far cheaper to replace than your frame.

And, always park next to a moron. I saw two expensive Cannondales parked at a museum last year. A two dollar cable was strung through the front wheels...which had quick releases...wasn't any crook gonna be looking at my 1983 Trek.

One more vote for the sheldon-endorsed technique: mini on rear wheel thru the stays, thick cable from the mini to front wheel... Not a bad idea to rig something for your seat too.

i have a u lock and one of those kryptonite chains attatched to it. i lock the rear wheel and frame to a sign post with my u lock and i get the front wheel with the chain. its also nice having the chain because i can just sling it over my shoulder instead of having to put in in my bag everytime i unlock

for short-term parking, i prefer the in-the-tree lockup.
dc's tree protection laws are quite strict, so i doubt any theif would dare cut down one of our nation's capitol's precious trees...

I'm a big fan of the Sheldon method as well. It seems that wherever I park my bike, there's plenty of bikes that would be easier targets. I picked up the bullldog mini and cable combo for about $30- I'm really happy with it.

Sheldon method with a cable for the front. however, these days you gotta worry about bars/stem and seat/post too.

I feel like you can't go wrong with a U-lock around the frame and rear wheel and something sturdy. Look up some of the post around here where people try to explain Sheldons method. It takes three pages and diagrams and some people still don't get it.

I think a crook is more likly to see you have a good lock on afixed to a permanent object and move to the bike beside you that he can lift over the pole that ruin your frame trying to pry the lock off. I can imagine a person looking at your bike(with Sheldon's method) and thinking someone screwed up and bending either the rear trianlge or rear wheel(and I'm not sure how difficult it is to saw througha wheel but I imagine its easier than a kriptonite u-lock).

Exactly. If a bunch of paranoid bike dorks don't get it, will a dim theif trying to work fast and not be seen? They'd probably take the nuts off the back wheel and chain off before they realized the predicament.
