as title?

yep

Just the cassette you have to worry about as that is where the smallest spacing is. So you can use a 10 or even an 11 speed chainset with a cassette and chain one gear less. 9 with a 10 spd crank, 10 with an 11 spd crank.

What about a 9sp chainring with a 10sp chain?

Darkside, FFS its called a road bike, are you twelve ?

^ or a racer 8)

10 speed chain wont ideally work on 9 speed chainrings as the chain is too narrow

That wasn't what was asked.

It'll be fine.

Yes, well 12 & 3/4 actually.

Sorry to upset you people, most road stuff appears to be called darkside on here so I was just trying to fit in! 😳

i,v running a Campag Super Record 10spd chain with 9spd quick link on my Morewood using the 9 spd cassette. A perfect change and looks uber pimp to boot. No glitches over the last couple of months at all….Go for it.
