I've just got my new XTR rear derailleur in the mail, and I've noticed that some of the bolts seems to be mad out of steel. Does anyone know if this is correct or not? Not that it really matters (reliability or weight wise), but this is the weight weenie forum, so I just thought I'd ask, to see if anyone could confirm/disconfirm this.

I edited the title, because I want to know about all possible weight saving options on the derailleur;)

I noticed the limit screws on RD-M9000 are now allen hex type and steel I think.

Thanks for the answer. If upgrading the pulley bolts, can i get away using alu bolts, or should i get Ti?

Alu is fine, though I prefer titanium.

Do you guys know the weight of the standard pulley wheels? Haven't got my torque wrench with me right now, and don't want to start taking things apart before I've checked the torque settings.

Dude stop worrying about every small detail :D

Shimano stuff is robust and the torque needed to tighten the jockey bolts is so little (2.5-5 Nm so make them just tight and don't crank on the allen key) just flippin' get on with it!

Just pull it apart and browse somehwere like R2 bike for comparison weights. There should be ~30g in the jockey wheels (Aerozine on ebay are super light, cheap and last well), alu bolts all over (eg Toronto Cycles) and Fibre Lyte outer cage.

I'm going to use the derailleur with a X0-cassette btw. Will I get much better shifting and/or reliability if I use a Goatlink11 or a RAD cage?

Anyone knows if this will improve gearing radically? Or am I better off saving some bucks, keeping the standard setup?

I've never come across anyone using either, nor ever describe the need for such a product therefore I wouldn't bother ;)

The one up rad cage was first designed to work with the larger "extender" 40, or 42T cassette cogs that fit behind conventional cassettes, so that people using 10 speed, could get closer to the gear range of sram 10-42T cassette. the stock shimano derailleur arm only worked well up to 36T. for its intended purpose yes the rad cage works very well. I live & ride somewhere very rocky where the standard carbon fibre xtr derailleur arm gets damaged within a few rides, where as the thicker, admittadly heavier aluminium cage of the one up rad cage, is still going strong.

If you're tuning the m9000 xtr that implies you're using 11speed. the cage of the m9000 will work perfectly with the stock xtr 11-40, by happy coincidence it also works with the sram 10-42. a few friends of mine are mixing m9000 xtr with a sram cassette with no issues. so for shifting performance alone, you wouldnt need the one up rad cage.

Found a site with a lot of tempting tuning bolts: http://www.fantic26.de/Bike-Tuning-Color-Concept-Parts-superlight-carbon-Bike-Components-MTB. There might be quite a lot of them that don't fit the M9000 though.

Sanded down the clutch lever for a much cleaner look;)

Just came across a company that actually makes a Ti clutch bolts for the XTR M9000 derailleur! I've been looking real hard for this, and just yesterday I found the clutch bolt for the last generation XTR on their site. I immediately emailed them, asking if they could please make this for the M9000 as well, and it actually popped up on their site today! What are the chances?!

Underneath is the link to the bolt. I've ordered one already, of course;)
Titanium Planet

I've recently also asked Toronto Cycles (among others), about making this part in aluminum (with a steel insert where the bearing is mounted), and they seemed interested, but they told me they're quite busy at the moment. Hopefully it'll happen eventually though.

Not M9000 but older XTR, just swapped my Jockeys for MT Zoom, original 17.5g, new 5.5g.

Was that 17.5 per pulley wheel?! That's a lot! I think it's right around 18 grams for the pair on the XTR M9000. I've got these ones with full ceramic bearings. Wight is listed with the steel ones. With the ceramic ones they're around 5.2-5.3 grams each.
