Not useful for much except maybe a short used kids bike that is probably not going to be passed down anywhere or for a similar BSO used in a similar manner.

For things like cables and housing I always recommend getting the absolute best you can because it can greatly improve shifting and braking for less cost then the other associated parts. I recommend nice slick stainless cables (ideally polished and always uncoated) and good quality housing and especially for brakes, compressionless housing works wonders. My favorite way to go is the Jagwire kits, Pro and Elite are the best way to go but even the Sport kits can be an upgrade for some bikes and you generally have a lot of leftover stuff so it is easy to re-use it for other builds.

I would also never use galvanized cables for anything and shops who purchase them are doing their customers a big disservice all the shops I have worked at don't stock it and if they ever had some it was usually purchased accidentally or was a panic buy from some novice buyer who may not know parts as well.

Bell is a helmet maker that is what they are best at and really all they do. I would not want them making other parts to use. I know they do have branded stuff at wally-mart and maybe they make it but I wouldn't want to use it unless in a desperate emergency.
