It all depends. Is it indexed or friction shifting? If it’s indexed shifting, you’ll need a freewheel that works with all the other drivetrain components. If it’s friction shifting, you can mix and match, although some freewheel cog teeth will be easier shifting than others. Maybe some of the experts here can advise you about what works best.
2. If rear deraileur(sp?) is bad, same question. Recommendations-whats decent? Will the bike "know" or not work or shift correctly if I put a Suntour deraileur on and leave the other stuff the same?
See above answer.
3. If bottom bracket is bad, go sealed?
That would be my choice.
Is there a standard size? Looks like these are only $20 or so.
You need to know what threading your BB has, as well as shell width and spindle length.
4. 20 year old chain on bike. Are there different sizes and what would it take?
There are different width chains, depending on the drivetrain.
5. Hubs-are these Sansin ones garbage?
Dunno. Experts?
I am hoping these are OK as I do not want to buy wheels. Will pull em apart and check bearings. The rear does not have quick release.
If the bearings aren’t pitted, you can pack them with fresh grease and you’re good to go. If the bearings are pitted, I dunno—Experts: Do you replace the bearings, or the hubs?
What are good solid middle of the road components?
You can get some really good
SunTour components for little money.
Yes.
