but you can save even more grams without loosing performance.
alu pins instead of steel ones in the pivot.
cf jockeys ~12g/pair.
ones again, really nice!
Alu pins wear out too quickly and the original steel pins weighs only 7 gr.

I would have titanium ones...
whoops saw your link, so it looks like ca. 40 grams savings on the cage and 11g for the pulleys, for about 50ish total on just those two changes. Not bad.
I am tuning an XTR M952 SGS and have ordered Tacx pulleys, aluminum pivot bolt, aluminum pulley bolts, ti pinch bolt, aluminum limit screws and an carbon inner cage.
I am searching for a carbon outer cage in SGS so I guess I will keep my eyes on ebay.
Great looking rear der. Mine will not be as good.
i have one question. how on earth did u guys take out the pins at the pivots? i have an xt derailler i am experimenting on and would like to tear it apart as it is useless to me already. hope someone can help me. thanks in advance
This is my method.
1st step: mark two circle on the back of the rear D like this.
2nd step: drill it with your hand hold like this.
3rd step: take one bolt to support the rear D like this.
4rth step: pressure down from where you drill to push down the pivot like this. (screw is to support the rear D)in picture i didnt put screw.
5th step: almost finish. use plier to take out the pivot.
