4' cable + u-lock: good for 19
I bought the 4' version of this cable as a secondary protection (along with a u-lock) for a bike with quick releases (seatpost and wheels). While the u-lock secures the frame and the rear wheel (using Sheldon Brown's "technique"), this cable secures the seatpost and the front wheel. I loop one end over the front wheel, pass the cable through the saddle mount, and attach the other end to the u-lock; when riding, I carry the cable looped on the u-lock.

I was afraid the 4' length might not be enough, but for my bike (19" frame) it is almost perfect; I say *almost* because I have to lower the seatpost for this setup to work (and depending on the exact position of the u-lock, it's still a tight fit). This is slightly cumbersome, but I prefer having to do that, than dealig with the extra weight / size of the 7' version.

In a pinch, you can also use it -- along with a u-lock -- to "secure" your bike to a place where it's impossible to attach a u-lock (a tree, a large lamppost), but the safety is highly reduced this way (as the cable itself becomes the only thing a thief has to cut in order to get your whole bike). I would only recommend that as a last resort.

In the first setup (as a secondary form of protection), I believe this cable is an excellent trade-off in terms of weight and ease of use. I highly recommend it in this case, for bikes with quick releases and sized 19 or smaller.

Plenty of lenght
This product works as intended and is used by me frequently. It works best when on trips where multiple bikes are on the rack and the cable can be weaved through most parts.

PROS: Coated Well, Long, Durable, Strong

CONS: None from me

Always use protection
I use one of these on my trunk rack to lock the wheels, bikes and rack all together in a big awkward mass. It gives protection from the passing by wheel thief. I use an extra tough padlock to lock this cable together. A determined thief will steal anything but with this at least it will take them longer.

PROS: Flexable, Long

BEST USES: Locking Wheels, Extra security

It does the job
It does the job. I bought the 30-footer and you can weave it through 3-4 bikes plus tires. Great product for a great price.

Very useful cable
Bought this cable to lock bikes together in the back of the pickup for shuttle trips, and ferry trips to the Sunshine Coast. Just needed a little piece of mind when we leave the truck and bikes in a parking lot while we grab some lunch etc. Thankfully the cable has never been tested by a thief, but it does add a great sense of security.

I would recommend this lock for others for the same usage, as well as those locking multiple bikes at the same location.

This cable doesn't...
This cable doesn't quite add up to a cable you'd use if youre locking your bike with a Kryptonite NY 3000 or NY Fahgettaboudit like I do. Its more suitable for lower level locks like the Kryptonite Evolution. If they made a 20mm version I'd get it. But its the best of what it is. Keep in mind that any cable no matter how thick, braided or not braided, cannot stand up to what a chain or u-lock can so be smart about how you use it.
