Wow, thanks Tmar - really useful info! It could easily be 7 speed at the back, although I thought it was 6. It actually came with 2 sets of gears - one was close ratio I think. Sounds like the best thing for me would be to buy a set of sora sti's and a new rear wheel maybe. Will my derailleur really be useless? Shame, as it is really nice. Is it a thinner chain or something then or is it just the movement of the derailleur will not be enough to go across if I have more gears at the back.
The whole bike is in very good condition as is all the groupset. You will see when I put up pics sunday that for a 25 year old bike it is in nice condition. Its done maybe 2000 miles in total, ever.
I can see it would make sense to keep the bits I take off for if I ever sold it. And to think it nearly went to the dump! My old man was about to junk it - luckily he happened to just mention 'my old bike' and I told him not to.

PS Bike shop up the road just happens by coincidnce to have a set of 7 and 2 sora sti levers. They are mis-matched. One has 'sora' and something computer compatible - the other just says 'shimano 7 speed' they are brand new, boxed with all cables etc and he wants $130 for the lot. Is this ok?
