I've worn out the middle chainring of my triple chainset, and I'm having trouble finding a replacement. I have an 8-speed cassette on my tourer, but all i can find are ads for chainrings and sets described as "9-speed".

Is there any actual difference between a triple chainsets and individual rings designed to work with a 9-speed cassette and those for an 8-speed?

Front derailleur is a Shimano FD-2303, if that makes any difference.

Yep it'll work fine. I run a 9 speed inner chainring on an 11 speed road bike no problem at all - the internal width of an 8/9 speed chain is the same so there is no incompatibility.

I use a 9 speed DA chain on my 8 speed DA - couldn't buy the 8 speed at the time, but as it's slightly narrower externally, you get less front mech rub.
