alu pins instead of steel ones in the pivot.

cf jockeys ~12g/pair.

Alu pins wear out too quickly and the original steel pins weighs only 7 gr. :wink:

What does the stock long XTR long arm cage weigh vs the 16g carbon version on ebay?

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.

What are cf jockeys?

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.

Joshie, buy the drill stand. hand drill wont simply work. 8)
This is my method.
Look here.

1st step: mark two circle on the back of the rear D like this.
Image

2nd step: drill it with your hand hold like this.
Image

3rd step: take one bolt to support the rear D like this.
Image

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.
Image

5th step: almost finish. use plier to take out the pivot.
