Eyup. I've got a 10s setup you might be interested in, i've just stripped my hardtail that I've not used in ages.
-SLX Clutch Rear mech m675 sgs £15
-XT 11-36 M771 cassette £20
-Shimano chain, might be Hg73? £5
-XT RH Shifter i-Spec... £25
Shifter is original i-Spec, but i've installed a "Problem Solver" SRAM mount, so it'll work with Avid/SRAM matchmaker brakes. Currently mounted to a really nice set of Elixir 5's (i think) that you can have for an extra £50 (rear brake needs a bleed).
