Some people have issues with this cable being easily cut, which leads to their bike being stolen. I want to set the record straight about this product and proper locking methods. These cables are by no means meant to be your sole locking device, but rather, they are meant to be used in conjunction with (ideally) a U-Lock. I work in a bike shop and attend school at Michigan State, a virtual candy store for bike thieves, and as such proper locking is imperative. First off, buy yourself a good U-Lock. I would recommend going with the Kryptonite brand, as they are THE name in bike locks. I myself use what Kryptonite calls the "Fahgettaboudit" which is an 18mm-thick, vinyl-coated monster that would make New York's most proficient bike thieves shudder. THIS IS WHAT YOU USE TO LOCK YOUR BIKE TO THE STATIONARY OBJECT, not the cable. Put the U-Lock through the frame and through the stationary object. You then use a cable (I reccommend a seven or four-foot KryptoFlex, again, for the same reasons) to act as a secondary security device and, more importantly, SECURE YOUR REMOVABLE COMPONENTS (such as a quick-release wheel or seat). Before closing the U-Lock, put one end of the looped cable onto the U-Lock, then loop the cable through your wheel and seat supports. Put the other end of the looped cable onto the U-Lock, close the U-Lock, and walk away whistling, because your bike is now un-stealable. That is the proper application for these cables.

Okay, so now to actually review the cable. It's amazing. You cannot top Kryptonite's quality, and it is very useful. It is also just as resistant to cutting as any other cable you'll find. Top-notch durability

Now, there's no doubt that when people walk past your bike, with cables snaking through it like some kind of evil invasive weed, and a five-pound U-Lock hanging off the side, they'll be thinking "Man, this guy (or girl) is really obsessed with bike security." But, hey, isn't that the point?

I bought all three 525 (5mm x 2.5'), 1004 (10mm x 4') and 1007 (10mm x 7').

Amazon seems to apply reviews of any of those products to all three products. So, be careful to understand which product a review applies to. For example, the 525 is a nice leash to keep your seat from walking away (while you step into a convenience store). But, it would take small wire cutters for a thief to cut. (Not a cable to use to keep your front wheel secure to a u-lock.).

The 1004 and 1007 models, at 3/8" diameter, is thinner than Avenir's 1/2" (12mm) x 7' cable. And, more expensive than the Avenir. Obviously, a little lighter to carry. But, perhaps less of a deterrent. Even though we're only talking about 1/8" difference, 3/8" tends to be the limit of smaller (concealable/affordable) wire-rope cutters. Having a 1/2" diameter cable could slow down a thief using smaller wire-rope cutters. Or, make a thief using the correctly-sized cutters draw more attention to himself (cutters to cute 1/2" wire rope are pretty large.).

I see people rate cables low because their bike was stolen. Everyone needs to realize that a cable is not adequate security except in low-theft areas. And even then: only for a quick trip inside a convenience store (to prevent the bike from being picked up and carried away). For everything else, you should use a U-lock. (Use that to lock the rear wheel through the chainstay/seatstay tubes to a bike rack). The cable should be loopped through the front wheel, seat and rear rack. Most thieves won't go to the trouble of cutting a cable just for a seat or front wheel. (More expensive front wheels have quick release axles and you're better off putting the front tire next to the rear tire and through the U Lock if you want more security than a cable.).

I recently moved to Minneapolis (which is very bike-friendly) and work downtown. Biking to work is a pleasure and it is nice to have a little piece of mind about the storage of my bike.

Also, I thought the cable would be inconvenient to carry, but it is not.. It can store easily in most bags that you would bike with, or around the handlebars or other parts of the bike. It has a little Velco strip that you can use to keep it looped up.

I definitely think that a longer cable like this 7 footer is a good idea (as opposed to one of the shorter cables). Once you loop it up for storage, it doesn't take a lot of space, and it offers more flexibility when you lock your bike.

This cable is very nice and flexible. It is plastic coated to keep it from scratching. My only complaint is that the ends are too big to thread through the places I need it to thread. The loop ends are two inches across and the orange cover over the ends are 1 inch thick. I bought this to lock up a mobility scooter and I could not get the ends through the handle of the battery box (which I want to lock up).

Looping cables through seatposts and quick release tires in conjunction with a Ubolt should deter the casual thief. Cables used alone are almost worthless. Still and all the best option is a case hardened (preferably through-hardened) 1/2 or 3/8th inch square linked chain (harder for cutters to grasp) secured by an impenetrable lock like the Masterlock 37-D with your removed front tire nestled in between your back tire/frame and the stationary object the chain is looped around with your quick release seat/post in your backpack/bag if you're gonna leave your valuable bike unseen for more than a few minutes. (Complete removal of the seat is another theft-impediment since it's not so easy riding off while standing up).

You can buy a Kryptonite fuggetaboutit 1/2 inch chain or make your own for literally a fraction of the price by googling ""campbell" "maxx" or "ultimate" security chain"" and ordering online by the foot. Be advised the 1/2inch, not counting the lock weighs about 2.6lbs/ft and the 3/8th @1.65lbs/ft. I've got a 3ft 3/8th inch chain trading off a little impenetrability for weight since I rarely leave the bike out of sight for long and never in an out of the way place where there's little foot traffic.
