Is that a cassette with a single sprocket or is it a SS hub?
Possibly new rear wheel £40 + cassette £25 ish. Or around £75 for a fully built up 9spd wheel.
Rear derailleur £30, you don't need a front one unless you're going for a double chainring but thats another £20 + chainrings etc.
If you keep those bars you'll need a bar end shifter £40.
If you change the bars thats £25 for the bars and £40 for a pair of STI's
Cables are gonna set you back pennies.
All depends if you need to change the rear wheel and change the bars.
