Nice bike! I've got the pink and purple 653 athena.
As regards 10 speed, you can get most of the way there. It's a bit difficult to see from the pictures, but I suspect you have something called 'shimano uniglide' on the back. What you can do is replace the freehub body for a 7 speed hyperglide one and then you can fit 9 of the 10 sprockets on! Your rear mech will work ok - i take it you're going for sti type combined brake/gear levers? Obviously there wont be enough clicks on your downtube levers for more gears than you've got, and 8, 9 or 10 speed on friction gear levers is horrendous (but it'll physically operate, if you've a steady hand!).
Good luck with it anyway.
thanks, sounds a bit more than what i wanted to do really, gear levers have changed since i last had a bike (ie on the brakes now!)
the thing with brake gears is your left with a space/hole where the old style gear levers went , its a tricky one, will have to think about it.
i suppose i could just go for say 12-25 7 speed on the rear? is that ok?
