Check ebay for the older stuff, or used upgrade parts.

I have a Shimano 600 set (8 spd) if you are interested let me know.

Of course it would, I can't see why it wouldn't



Check ebay.


Not for 8, but 9 speed, yes.
The frame might not be able to accomodate 8/9 speed. For 8/9 speed the rear spacing needs to be 130mm (IIRC it was 126mm for 7 speed)

Artificial Intelligence can never beat natural stupidity.

If you don't have any luck on ebay looking for the RX100 levers then Modolo Morphos shift levers work on Shimano 7,8,9 and Campagnolo 8 and 9 speeds. They're not cheap (around $200 US) but might be an option. http://www.giroposte.com in Canada has them. Try emailing / calling http://www.yellowjersey.org as they have a really big stock of all kinds of out of production parts.

you can get 7sp STI shifters new from Sheldon Brown,

but they're $130, quite a piece of change.

Upgrading to 8spd requires only a cassette and shifter change, everything else in the drivetrain should work fine. I'm using a 6spd derailleur with 6spd crankset on an 8spd bike which is my race bike, the shifting is fine.
For 9spd you may need a new inner chainring, and certainly a new chain. I'd try the der first on 9sp before buying a new one, it might well work - with the appropriate high/low adjustments of course.

"It is a good feeling for old men who have begun to fear failure, any sort of failure, to set a schedule for exercise and stick to it. If an aging man can run a distance of three miles, for instance, he knows that whatever his other failures may be, he is not completely wasted away." Romain Gary, SI interview

I might be getting rid of an 8 speed cassette soon
