8 speed compact?

Hello out there,
I'm a forum virgin and have a single burning question which nobody seems able to answer to my satisfaction: CAN YOU FIT A 9 OR 10 SPEED COMPACT CHAINSET TO AN EXISTING 8 SPEED SHIMANO OR CAMPAG SETUP?; (and if you can can someone recommend a reasonably priced example).
I don't think its a lot to ask in this new and bewildering age of the interweb hyperbyway or whatever they call it in techno-babble. There must be another sad, skint and fourty-something bike lover out there who can't afford (or want to waste the wonga on) a new bike, and wants to keep his beloved steel steed running in the shiny new millenia.

I'm moving this thread from Regional-UK to Bicycle Mechanics, where it will hopefully receive scores of answers from other sad, skint and fourty-something bike lovers.

If you stick to an 8 spd chain and your old FD there shouldn't be any trouble using a 9/10 spd cranks/chainwheels. Come to think of it, odds are that a 9-spd chain will run fine too.

9 speed chain should work fine; but why not just use 8 speed (e.g. SRAM PC870), which are still widely available?

That wasn't the OP's question. He wanted to know if a 9 or 10-speed compact crank would work with an 8-speed cassette and chain.

Yes it should. You may have some rubbing of the chain on the inside of the large chainring when you are in the small chainring and the smaller rear cogs. A 9-speed chain will reduce this problem and will work with your 8-speed cassette.

yes it should, but to be safe get a 9 or 10 speed chain to make sure.
i remember not too many years ago, you could get a cassette adaptor to change from 8 speed to 9 or 10 - well on campag you could.
