YEs know what you mean NigelIt is quite easy, a 9sp cassette is 1.1mm wider than an 8sp one usually a free hub supporting 8 will support a 9 though you only need a spacers for 8sp on 11sp freehubs or 7sp on 10sp hubs . most 8sp RD will cope with a 9sp cassette (I currently run an old RD3300 Sora 7/8sp on my nine speed), changed the shifters twice from 7 to 8 and 8 to 9, M.T.B. are cheaper to do as you are only changing the shifters,
On my road bike the difference that one gear made was quite unbelievable my 8sp was 13-15-17-19-21-23-25-28, but I was finding sometimes especially into wind I was in either to high or too low a gear for a nice spin rate so when I upgraded it to 13-14-15-16-17-19-21-24-27 its much easier to find the right gear, I don't like the jump from 17-19, so when I can afford to I am going to change it to 17-18-20-23-27. and using the 30th front I have three gears in the 50-40" range compared with just the one on the 40th ring 30x16-17-19, its not a combination that's used often but it gives other options
I find can't get the right gear, but end up spinning more
Not changing anything this year but wonder if a 10 speed would be better
It's the biggest change between how I ride now and years ago is I aim for higher cadence now
