mid 70s Raleigh, convert to 9 speed?

It's a 10 speed, mid 80s Raleigh, can I put a 9 speed cassette on it? Would this require a new hub? I'd like to put a set of index shifters on it, rather than the downtubes...is it possible? What combination of derailuers/shifters, etc...

Or would I be better off just upgrading the derailuer and keeping the friction shifting?



I really want to get rid of the pastic simplex:


Would something like this work? http://cgi.ebay.com/CAMPAGNOLO-ROAD-...742.m153.l1262

You would need at _least_ a new hub. Unless that bike is of extreme sentimental value to you, or weighs 0 pounds, when all is said and done I am not sure it would be worth the time/money to update. Just my opinion, though... One man's garbage is another man's treasure they say, and I'm guilty of wasting time on projects that aren't worth it as much as the next guy . Good luck. BTW friction shifting is fun, my 1984 Raleigh Prestige is completely original and I wouldn't have it any other way.

Cleaned it up a bit more, put on new tires/tubes (not the coolest tires, as I'm trying to keep this on a budget) and a saddle I had laying around...looks a bit better...now to replace the derailleurs and give it a tune up...should be a decent little rider for less than $100 total I think.

I would put a 3 ring crrankset on it before I would put on a 9 spd rear cassett. You might be able to space out the axle for a 6 speed freewheel. I have several Campy rear hubs that came set up for a 5 speed freewheel but also came with a replacement longer spacer for using a 6 spd freewheel. That said, I've never lacked for enough gears with a 5 spd freewheel and 3 chainring front crankset.
Here's a pic of my touring bike with a frame I built in the 70's with a 5 spd freewheel and 3 ring BioPace front set. I have freewheels with everything from 14-24 to 14-34 chainwheels on them for it.

That would be my vote. Find a Sun Tour derailleur, and possibly some indexed/friction downtube shifters. Spreading it out to work with a 7 speed would take minimal effort an expense. Add appropriate spacers and a 7 speed freewheel that is compatible with the shifters - make sure the dish on the rear wheel is correct, throw on a 7 speed chain, and you're good to go (although I would also suggest having the rear dropouts properly cold set to ensure alignment is consistently perfect).

Going to 9-speed? Huge waste of time and $$$ on that old Grand Prix.
