What determines it? The manufacturer surely. They slap the label on.
What's the difference?
Chain rings, tabs, chainline. Some or all of these.
Are they in anyway interchangeable? I suspect that this may be the root of the question. Answer, maybe and in some circumstances. Too many variables to be 100% sure that non-standard fitments will always work.
Theory over. In practice I have never has a chainset play up if there are less "speeds" than it is made for. The other way can play up if using some form of front indexing as the gap between them (the tab) is too big.

Re: Rear reflector for saddlebag?
If you are after legal then get some lights.
if you are not then forget red, it is not as bright as other colours. Around our way there are millions of power line poles with bands of reflective yellow or white plastic on them. Some have 2 or 3. Many are in the woods! At least one band I know of was fixed last year to a pole that's been lying on the ground for years! Done for a laugh I guess. Search some out and liberate some. The colour will tell drivers that there is something there that doesn't need hitting. Way better than cycle reflectors and can be cut with good scissors. Those plastic road side markers are red. Plenty of them flattened by the side of the road.
The white/yellow stuff makes brilliant mudflaps as well.

Re: Bike Safety Checklist When Replacing Parts or Building New Bike
Rear lever pointing forward under chain stay can't get caught. Pointing back can. 1st is easy to undo as it should not be forced shut. I have seen idiots kicking theirs shut rather than back it off a touch.
Quite possibly some of those nasty external can Qr's might not be fool proof but only an idiot would use them if worried about security.
And of course some people may not know any better. They'll learn.

Re: The Disc Brake Naughty Corner Thread
Also just like MTBs going to disc brakes. You know what? These bikes with both wheels the same size will never catch on. Fancy having all those rods and cables to work the brakes.
For goodness sake, stop arguing. Both types work fine for their fans.

Re: The worst place in the UK for cycling?
Any town , full stop.
Natural features are all good so hills can't make a place bad. I would suggest that the greater the presence of humans the worst the place can be.

Re: Wild camping, wild boar
Come and practice here in the Forest of Dean. Hundreds of the things about. Mums don't like you getting to close to the young and can have a go at dogs but other wise they are nice enough. Smelly buggers though.

Re: People shouting 'left' 'right' etc on a cylce path whilst approaching from behind
I can't help but to disagree with the Utility cyclist in one respect. Not to speak is plain rude. It gives no warning to those you are passing that you are there and being surprised isn't nice. Courtesy to the other person if nothing else.It's for their benefit as much as yours.
I don't disagree that the overtaker has responsibility for their actions but the world is full of idiots and they turn around when surprised. Often into you. Creeping up on them is not being clever, its missing a trick.
As to what to say, "left" gives nothing. "On your left" says everything.
Bells are bloody useless. So often am I told by some dozy so and so, (usually elderly ) that as I should ring my bell after I have. I quick example and an "I did" just gets a grunt. A nice polite " morning" is all it needs unless you are ignored. Then it's "excuse me please". Never needed anything else in 4 decades.

I have had a grub screw holding the cable guides under the frame catch a BB before .Not sure if such a thing could cause your problem but it maybe worth a look.

Re: Front derailleur cage close to back tyre
Assuming the wheel is built straight and is central then it could be that any spacers between chain set and frame are on the wrong side moving the chain set over a bit.
Or it could be design.
Can you have a look at another one ?

Re: Grade C Bike
Depends on so much.
Is there a warranty?
Have all worn bits been replaced as us often the case with ex hire bikes? I,d expect chain, cassette, tyres, brake blocks or pads and maybe cables.
What is the state of the bike?
What is the price?
What quality is the bike?
25% off retail isn't worth it unless it's a rarely discounted model with nothing more than the odd tiny more, that is the only thing you would consider.
I'd buy such a thing if the price was right but not if it wasn't a bargain.

Re: Issue with rear hydraulic brake.
You are doing the rights things regarding the squeal.Check all is tight as well. As for the bleeding, well every brake is different so I can't help there but it looks as if the rear still has a touch of air in it.
