700c vs 26"

Do you think every town has a LBS? Or even one that is conversant
about
tyres?
And what if I see a 700B tyre? What's the difference between a C and a
B? Is the B going to be suitable for my rim? And what does the 700
refer
to anyway? If you measure your rim it's nothing like 700mm. Does it
convert to inches somehow? If I'm swapping my singles wheel with my
clincher wheel how much effect will it have on my speedo?
How the hell do I know if the manufacturers won't tell me!
For a while Velocity were making wrong sized rims and insisting the
tyre
manufacturers were making bad tyres. How do we work out who's right?
I just bought a Continental ultra sport that has 700 by 23C written on
it, is that the same as a 700c? Will it have the same diameter as 700
by
25? If the outside diameter is different then why do they call it 700?
These are things I like to know.

Every industry has their own terminology, rules, etiquette and
standards. They are not explained in detail, on every item, all the
time. Purchasing requires a little knowledge of the industry. This is
why there are websites like Sheldon's, books like "Food Blending for
Dummies", magazines like "PC Buying Tips"..

I assume you own a PC and use it to post here. When you bought it you
probably learned at some point what USB, SCSI, IDE, PCI, RAM, ROM, HDD,
FDD, PCIMCIA, etc meant.. right? Same deal with bikes and any other
industry - you might need to buy a book, browse a website or ask
someone for information. Try asking here
