Carrying a lock

[mary9761]

sounds like you have the same type I have pooks. I don't know if you all can see in my avatar pic, but I wrap the lock around the head and top tube on my Navigator and that's where it stays. I've been known to take the bike into the vestibule at Kroger's and lock it right up to the freebie magazine/flyers rack while I pick up a few groceries etc. I alway make sure it's wrapped around the frame AND the handlebars though to make it a little more complicated for an HONEST person well, doggonit, I'm trying to insert a photo and it won't open the pic for some reason, but if you click on the link it's a bit of a closer look.
Gotta be careful with the combo bar locks though, there's a little button so you can CHANGE your combo and if you accidently click that I've had to have a lock CUT OFF because I did that and get a new cable lock that bites and is embarassing to have happen (at least I was right in the same shopping area as my LBS)

I also just have a cable lock with a number combination thingy on it. The cable is tripple layered kevlar so theoretically should take some time to cut through, and it is fairly heavy. But I just throw it in my bag (or attach to the outside of my bag) when I take it along. If I am going somewhere where I need to lock my bike up, I will generally also have a bag with me of some sort. Otherwise I guess I'd wrap it around by waist. At work I leave the bike in my office. When I'm at Uni, I bring the lock (and every other day I forget the lock, realize half way there and have to turn around). So far I've been lucky. No stolen bike even the day when I didn't lock the lock properly and realized 10 hours later when I was about to head home. I do strip everything else off the bike though such as lights or computer. And I make sure the lock goes through both wheels and the frame and the bike rack.

I carry a U-lock in a side pannier and also have pit locks (I believe they're called) on each wheel. They lock the wheels and open with a key. The U-lock definitely adds to the bike's weight but it adds at least a little sense of security.

I have three locks:

A Kryptonite cable lock - it's a little heavier cable than what I've seen described as a latte lock, and uses a key instead of a combo.

An armored cable lock - this thing actually has some sort of metal covering over the cable. It weighs an effing ton, and the key looks a lot like my house key.

A U-lock of the new variet that isn't pickable with a ball point pen.

I never use all these locks at once (that would be just plain silly); in fact, most of the time I have just the regular cable lock. It lives on my seat post, and yes it rubs up the paint a bit. I don't care, my bike's a fairly inexpensive bike that was intended to get me places and not to look pretty. I'll swap that out for the armored cable if I'm not sure where I'm going to wind up for the day. If I know I'll be somewhere where I have to leave my bike unattended for more than a half hour, I throw the u-lock into my backpack and keep the lightweight cable on the bike - when I'm at lockup, I make sure the cable runs through my rear wheel as well as the frame. If I have to leave my bike overnight, then I do the same but with the armored cable AND I take my lights and computer off of the bike.
