I have gears myset up: HUB Hope pro 2 trials CASSETTE one I found in the bin of my local bike shop, it was a 7 speed I think. It was bolted together, I undid it and replaced the 7spd spacers with 8 spd and removed a cog. The bolts still fitted (it might actually have been a 6 spd, I cant remember) CHAIN kmc narrow, 8spd SHIFTER Old skool sunrace 8spd thumb shifter. It has the option of being a friction shifer (not indexed) so I just move it until its inline with the cog I want. The advantage of this is that I can run whatever spaced cassette I want, also if the mech gets bent I can fine tune its position to get it running as sweet as poss. Also, cable adjustment isnt as important. MECH XTR reverse pull, shotened cage. I chose a reverse pull because if my mech cable snaps, it will automaticly return tothe largest cog (better for trialsing) and can easily be adjusted to the right cog with the limit screws. Also, it means the arm on my shifter isnt pulling much cable to the arm is much lower in profile, as opposed to sticking right up and snagging on clothes and stuff.
