swapping 9 to 10 speed
Discussion
I've got an old Specialized Tricross i use as a winter bike, as it takes full mudguards and I' not precious about the paint.
I think the cassette needs replacing, as it occasionally slips under extreme pressures (steep hills) which is a bit confidence-sapping
Is it possible, or even worth, replacing the brake lever/shifters at the same time to move on from 9 speed to 10 speed? Or is it a waste of time and money, or even not cross-compatible?

As noted, it's quite an involved and expensive business to do it the official way, and all for only one more gear.
If you don't mind a bit of a hack (and non-indexed shifting) you could do it on the cheap by using a bar end friction shifter to control the rear mech, and keep the brifter as just a brake lever.

Shifter compatibility is a multi-dimensional swamp.
The 'sheldon brown' website may help.
You can get mid-cable gismos to fiddle ratios.
10 speed rear mechs are not dear secondhand, but 'long cage' was at a premium when I was messing about.
Don't assume a MTB cage will fit on a road mech :-(

Doesn't seem worth it then. It was only because the levers were cheap.
How is the rear mech different? I thought that the shifter defined the amount of cable pull, and the the rear mech was just a "dumb" part of the process.
Slightly different geometry so they won't index with the later levers. IIRC with Shimano, 7 to 8 speed you could reuse the rear mech, but not since then.How is the rear mech different?

You'd have to change the rear mech as well, because the cable pull is different. So it adds up to quite a bit more than just bunging a new 9 speed cassette in.
This isn’t necessarily true. Newer 10-speed Tiagra is different but older 10 speed sti shifters will work fine with your current front and rear mechs, as will 10-speed 105, Ultegra and Dura Ace.
Having said that I wouldn’t bother. What I would suggest however is when you replace cassette and chain, use a 10 or 11-speed chain instead. They shift better on a 9-speed drivetrain. Ok, so the difference isn’t massive but it is noticeable.
Oh, and use posh cables and housing too. Jagwire Road Pro is my current favourite.

You're right, I should have googled before relying on my increasingly dubious memory of these things. Sorry to confuse the OP...Newer 10-speed Tiagra is different but older 10 speed sti shifters will work fine with your current front and rear mechs, as will 10-speed 105, Ultegra and Dura Ace.

Got some 10 speed 5800 105 rim brake brifters you can have for the price of postage if they are of any use I think the cassette needs replacing, as it occasionally slips under extreme pressures (steep hills) which is a bit confidence-sapping
