Some lock advice from a locksmith
#177
The sheldon locking method (u-lock through the rear wheel inside the rear triangle) works very well.
Earlier tonight I found my chain dropped and my rear wheel unbolted from the track ends. Apparently someone made an attempt to take the frame but failed to separate it from the rear wheel thanks to the u-lock. The only thing that sucks is that the rear rim has a few small scuffs and markings from the guy trying to force / tinker the lock off, but it's just cosmetic.
Granted, if he REALLY wanted the bike he would've found some way to get it. But it seems that proper locking at least helped to demotivate him from continuing to try.
I also had a second u-lock through the front wheel AND a cable through the saddle, securing both to the frame, so there was no loss at all.
I'm still pissed off about the scuffs on the rear rim though.
****ER!

I prefer to put a lock through both, the rim and the frame, but u-locks are REALLY narrow, and depending on what you lock to and your type of rims (I have deep section ones) sometimes you can't do both. That was my case tonight, so the next best thing was the u-lock through just the rim.
It worked. Not ideal but it worked.

SB's method looks real insecure but I rather come back to a dropped chain than to a missing wheel. If i lock up over 15min I run a cable thru the front wheel too. Makes it look a little more secure plus an additional cable weigh almost nothing to carry around.
nate, glad ur bike is not stolen.

Nate - you know that thief was probably thinking, "Stupid bastard only locked his bike through the rear wheel!" too. The Sheldon method does look like it wouldn't be very effective at first glance but it's pretty damn secure. I'm glad your bike didn't get stolen.

I try to keep my bike with me. i hate locks. Also when i do lock it. I use a boat lock for the frame. two ulocks for the rim.
But i my self carry the tools i used to build my bike. Witch mean some one else does too, and i could easily get my stem stolen etc.

Since my wheelbase won't allow me to lock the real wheel and seattube with my u-lock, instead I lock the rear wheel and the seatstay near the brake bridge (with the ulock in the rear triangle as opposed to being on the outside). It is just as effective as SB lock method plus it looks more secure and there isn't any room to fit a jack or anything. Also, with my bulldog mini it leaves just enough room for my helmet.

Sometimes I just lock my crank arm to a fence with my u-lock through the chainring.
Seems like removing all the chainring bolts and the pedal (assuming the thief isn't carrying around a BBT-5 to just pop the crank off) wouldn't be any faster than just cutting the lock to begin with.
Still though I only do that when I'm jokin' around and just getting a tequito from 7-11 or something.

ichitz, yeah I usually carry two u-locks and one cable.
One u-lock through the rear wheel/rear triangle, another one holding the front wheel to the downtube, and a cable running from the saddle rails to the rear u-lock. That's worked out well so far.
lulz. Pretty much. Got drawn in by the illusion. Got thwarted by geometry. I really don't know how the scuffs to the rear wheel came along. Looks like he was trying to fiddle with the lock with some tool. Maybe jamming his wrench between the lock and the wheel, trying to use it as a jack, or just wedge it off somehow. I'm kind of baffled.
Looks like, except for unbolting the wheel and loosening the chain, the guy had no goddamn idea what he was doing. Realized he couldn't pull off the quick boost, so he bailed.
This is something that I've done a few times. Definitely safer. Need to be in less of a rush to lock up and do it more often.
Anyways, thanks guise. I'm glad the bike is still here with me.

Sorry to hear about the scuffed wheels...good thing the thief didn't take extreme measure to yank your wheel out.
Also, interesting post from General Cycling.
Also, interesting post from General Cycling.
When someone buys a nice bike, often their first question is: What is the "best bike lock" I can buy? Or, who makes the "strongest bicycle lock" money can buy?
The April 2005 issue of UK's "Cycling Plus" included the results of their 2005 lock tests. Cycling Plus tested the locks by trying to break them with manual tools favored by crooks and then cutting them with the type of portable, battery-operated power tools used by crooks.
SHORT VERSION OF TEST RESULTS: The Kryptonite New York 3000 U-lock is the "best bike lock" and the "strongest bicycle lock" for high crime areas and an expensive bike.
The OnGuard Bulldog Mini U-lock (just $24 at REI) is the "best bike lock", and for its low price, "the strongest bicycle lock" for average neighborhoods and for less expensive expensive bikes.
The European models: the Squire Paramount Plus, and the Axa-Basta Secu-City Plus model did almost as well as the New York lock. The German-designed mid-price Abus lock, was only "average" against power tools.
LOOONG VERSION OF TEST RESULTS: The tests using manual tools had one scary and surprising result: the locks were so strong that when heavy force was applied to the locks, the frame of the bike got mangled, while the locks remained in good shape.
To prevent damage to the frame, and to fully protect both the frame and rear wheel, position your lock around the rear wheel, just behind (but not around) the seat tube. That locking procedure secures both the frame and rear wheel. If a crook uses a prying method, he might bend the wheel, but he won't damage the frame.
HOW TO CORRECTLY LOCK YOUR BIKE by Sheldon Brown:
www.sheldonbrown.com/lock-strategy.html
RESULTS BY LOCK TYPE:
- CABLE LOCKS: Cable locks are a joke. Most lasted just a few seconds. None lasted long. A cable may have some value for protecting your front wheel or your helmet. They have ZERO value for protecting your bike.
- BARGAIN U-LOCKS: The OnGuard Bulldog Mini U-lock ($24 at REI) was as strong as the top ranked Kryptonite New York 3000 against manual attacks. But, OnGuard locks don't last long against power tools, so the New York 3000 remains the top choice for "high end" bikes parked in Manhattan and other "crime centers".
- KRYPTONITE - The Bad News: Their second best U-lock, the Evolution, failed against manual tools in just 95 seconds, after the application of massive force. The leverage force applied to break the Evolution was so massive that the frame of the bike was mangled during the attempt. A good reason to put the lock around the rear wheel, not the frame.
My personal interpretation of the test results is that NO Kryptonite U-lock using a "single bolt" design is likely to last more than two minutes against a skilled crook.
The Kryptonite New York 3000 is far more effective than other Kryptonite U-locks because it uses two bolts to lock both ends of the "U" shackle, just as OnGuard does with every one of its U-locks. Then, the New York 3000 adds "cut resistent" steel to the shackles, making it about 400% stronger than OnGuard's best locks against (the very rare) cutting attacks using power tools.
MY SUGGESTIONS: If the crooks in your town use ONLY manual tools, and will never use power tools, buy the $24 OnGuard Bulldog Mini (or a larger Bulldog if your bike rack requires a larger lock). A compact lock provides less space for a crook to insert his tools, so buy the smallest version of the Bulldog that will fit around your rear wheel and your bike rack.
But, if you park on a "mega-sized urban college campus, or in a "high crime" area where Pro crooks have been known to power tools against targeted "high end" bikes, there is only one U-lock widely sold in the USA that really works: the Kryptonite New York 3000 Lock.
"Cycling Plus" did NOT test heavy weight chain locks in the April issue. However, in a previous CP test, the 8 1/2 pound Kryptonite Fahgettaboudit Chain lock lasted about eight minutes against power tools, compared with ten minutes for the four pound New York 3000 U-lock.
Because the four pound New York 3000 is the stronger of the two, the only reason to buy the eight pound Fahgettaboudit is if you lock your bike to telephone poles or large trees, or other objects that are too large for the New York 3000 U-lock.
USE YOUR HEAD: No lock lasted much more than ten minutes against power tools. Park at locations where only the dumbest crook would employ power tools for ten minutes. Lock your bike next to the ticket booth at the movie theatre, not in the dark alley behind the Theatre.
For "over-night" parking in a high risk area (never a great idea) consider combining two or three good locks. Most criminals are too lazy to work hard for twenty or thirty minutes. If they were willing to work that hard, they would not be criminals. A crook facing TWO New York locks might see the advantages of going out and finding "honest work".

Any good way to lock a wheel with track nuts to your frame?
The locking fasteners I can find aren't available in 9X1mm (front axle size) and don't look like they'd fit a fork. I know about pit-locks, but they only work on quick release wheels. They sell a 10X1mm nut (rear axle size) but it's over a hundred bucks for two nuts and a tool.

vix, interesting article.
I was thinking about getting a evolution mini for shorter lock periods because carrying the 4lb NY lock around just for a 5min stop is a little annoying. I know.. htfu. I guess i should get the on guard instead then.
And also good to know the NY ulock lasted longer than the NY chain.

i was locking up quick with two frames, two locks, and one cable. of course i took the time to avoid the recently infamous philadelphia exmeter poles, but i didnt really dissect this locking scheme at the time. its double modified sheldon, which is rear rim and seat stays, with an a to b snaked cable. it ended up being fine for the short duration of the lockup, but while i thought it was quite elegant, is this scheme flawed? click to enbiggen.

Would a longer than needed kryptonite new york chain lock be more vulnerable than a shorter one when locked to the same diameter post? As my friend kind of went overboard when he bought the 5 foot fahgettaboutit chain; and I'm trying to get him to return it and downgrade to a shorter model.

Personally, I filled the seatpost clamp, seat clamp, stem top, and one handlebar clamp bolt with shoe goo, then topped off with superglue. A bit of picking will get it out, but it'll take longer than most casual thieves would be willing to deal with.
Note: Using full superglue is commonly recommended, but will require the use of acetone or major patience with a small sharp pick to remove. By using shoe goo, which is flexible, beneath the superglue it is easier to crack the coating of superglue if the bolts need to be removed. It still sucks enough to hopefully deter theft, but it sucks less than full super glue. The thieves will hopefully see the superglue layer on top and move on.
I'm currently working on a way to keep my wheels on without needing a cable or second lock.
