Anyone else met with trouble when trying to find replacement parts for 9 speed systems? My front derailleur needs to be replaced and almost all of the bike retailers seem to only stock 10 speed things these days. While I’d like to take this as an opportunity to upgrade everything, I still need a decent replacement part at a good price!

I think I have one at home I don’t need. Let me check and I’ll email ya.
First, I’m betting you’d find one on ebay.
Second, I’m not 100% certain, but I’m pretty sure a 10 speed FRONT derailleur will work just fine on a 9 speed setup. Not true for a REAR, though.

The 10speed front der is narrower than is the 9spd due to the different chain widths. They don’t work well as replacements for one another. Technically it will work but you have an extremely narrow range of gears in the rear due to the decreased margin. You will hate it.
PM sent.
The front derailleur does not care whether you’re running a 9 or 10 speed cassette.
You should be fine with a ‘10 speed’ derailleur!
You will find neat explanations concerning drive train part interchangeability on ol’ Sheldon Brown’s 6-speed, 7-speed, 8-speed, 9-speed, 10-speed? page.
It is true that a lot of LBS’ do not stock 9-speed stuff anymore. However, there are still plenty of 9-speed components being sold online. They are typically way cheaper than their 10-speed counterparts.

That is true, it does not care about the cassette. I am telling you though that the front der on the 10speed is more narrow than that on the 9. If you use a 10spd der on a 9 spd chain, you will not like it because the der is sufficiently narrow as to limit the range of gears you can use in the rear before the chain rubs the front der. It sucks.

Well, it will teach you 2 good things:
Yes, you will be more discouraged to use the extreme gear combinations (big/big & small/small), but you should avoid those anyway!

Sigh.. go for it. Some people must convince you they are right at any cost. Have fun using your mismatched gear.

Actually, both Campag and Shimano rear mechs have the same cable pull sensitivity for their 9 and 10 speed versions, it’s only the shifter indexing that’s different. For Campag, the cage is slightly wider for the wider chain - fatter jockey wheels (actually just the bearing end plates) and longer joining bolts are the only difference. The carbon caged 10sp versions use 9sp jockey wheels to give a little extra clearance given the potentially greater consequences. I imagine Shimano mechs have the same or less difference between 9 and 10.
For front mechs, the cage is narrower for 10sp to match the narrower chain, so better to get the right one. Campag 2001-2007 approx had an insert, to be removed for 9sp. Should be plenty available on ebay etc, maybe even some NOS.

I ran a 10spd FD on my 9 speed bike for a while. You both are right. It sucked because it was narrower and somewhat limited gear ranges, but to make up for that I just had to constantly be trimming the FD if I started to get a little bit of rub. It can be done, but it does suck.
To the OP, I may have an ultegra 9spd sitting around at home. PM me if you can’t find one (braze on) and I’d let it go for cheap/shipping.
A 10-speed FD will work, but as others have said, the cage is narrower than 9-speed and you may end up needing to trim it more often after rear shifts. I am actually using a 9-speed MTB FD on a 7-speed bike and have the same issue but it doesn’t bother me - I have bar-ends on that bike so front is friction. Brifters may not provide sufficient trim ability.
I still use 9 speed stuff on my cross bikes, I find if I google the part number there is usually a shop with one still in stock and barring that I can get one new or used on EBAY.
It’s getting somewhat harder to find the good 9 speed stuff, 105 seems plentiful still.
on the contrary, the shimano 9sp and 10sp RDs are completely interchangeable.
