8 & 9sp rear mech's are pretty much interchangeable as far as I am aware, there is 0.9mm difference in the cassette width between an 8 and 9sp so it is feasable that some 8sp wont work on 9sp, the cog width there is only 0.02mm difference so you could use 9sp cogs on an 8sp and vice-versa, but not a 9sp cassette with 8sp shifters or 9sp shifters with 8sp cassettes, in either case, if you split the cassette (take out the pins/screws holding the cassette together) you can make up your own ratios. This coupled with a M.T.B. rear mech allows you great freedom of choice. My current set up is 52/40/30 front and 13/15/17/19/21/23/25/28 giving me a range from 28" to 105" I could go 26/30 on the low end without it upsetting the ratios to much, to give a low gear of 26.3", I would need to be climbing some really steep long hills for that these days, but the option to swap them is good.As funds for the bike I would like are not there I have also been considering Triban - the 3 and 5 are both triples which suits me. (Especially older model red Triban 3). Also looking at secondhand market.
Was interested that @Nigelnaturist has put on MTB rear mech. I struggle a little knowing the compatability of different parts, for example I see a certain bike and wonder if it would take a 11-32 cassette.
So for the time being will look for a road bike - never going to to have enough time to do up the 1980's Claud Butler with Reynolds 531 frame.
However seem to be doing ok on the hybrid for now
