Wanted: Short cage rear mech, road cassette & flat bar shifter

Going to do a gear conversion on my ss bike. I have a hope trials rear hub so I'm after a road cassette that I can spilt and make a custom 6sp to fit.

Edit -

Now only require

• An 8 or 9 speed shimano/sram road cassette.
  
• Corresponding 8 or 9sp chain.
  
• 8 or 9 speed rapid fire flat bar shimano shifter (ideally xt or xtr)
  
  

:)

I presume that's a shimano cassette fitment? 9 speed HG70 cassettes (& possibly lower spec) can be broken down easily due to the pins that keep the sprockets in place as opposed to the higher spec ones that had integrated sprocket clusters. Of course 7 & 8 speed would also be fine though are generally all steel sprockets.
As for shifter, do you want friction or indexed, you can still buy top mount 6 speed indexed shifters off ebay for not much. The advantage also is that with a flick of a switch is can be used in friction shift mode for any amount of sprockets http://www.ebay.co.uk/itm/SHIMANO-MOUNTAIN-BIKE-PAIR-TY2O-INDEXED-TOP-SHIFTERS-SUIT-6-12-18-SPEED-NOS-/180786195653?pt=UK_sportsleisure_cycling_bikeparts_SR&hash=item2a17b26cc5
though if you're using the same cassette spacers say from a 9 speed cassette any deore/LX STI shifter will work fine.
As for a rear mech, pretty much any mech will do as they are not speed specific so do not have to match the shifter necessarily.

Ultegra 8 speed with new clear glass fibre jockey wheels....if you are interested i'll check model number and supply pics.....£12.50 posted...all clean and shiny

Mr bump, I used to ride street/trials and did just that with cassettes; punched out the three pins or unscrewed bolts in the hg70 variety. Shifter wise I'm after a rapid fire system..i.e x.9/x.0 (sram) or xt xtr (shimano)..
