For the newest SRAM type 2.1 derailleures, are there any realistic difference between X9 and X0 besides 35 grams and color?

I can't find much of a difference when I was looking to switch to SRAM last year. I thought for the price difference it would at least came with some ceramic bearings...but it doesn't.
I got a X9 and replaced the steel adjustment screws with aluminum ones...it weighs the same as the X0 now.

Thanks for the input. I'm thinking of just getting a X9 then. Where did you get the aluminum screws? Hardware store?

Aren't the pivots different, where the X0 has C-clips holding it all together and the X9 is rivets? My X0 is much more robust and tight as compared to an X9 I ran a few years ago... There is a difference, the X0 is built better... Have close look at both parts and you will see what I'm saying...

I don't doubt what you are saying since I didn't have two to compare side by side. At the time of ordering I didn't see the additional cost to be worth it for what you'll be getting with the X0. What else is different besides the C-clips? There has to be more for the 100+ dollar difference? The SRAM site doesn't say too much.
I am using an X0 shifter. So the money I saved by going X9 with the RD...I went X0 with the shifter...where I feel that it'll make more of a difference.

Im thinking of getting an used XX shifter to run the X9 dérailleur. Or maybe I'll give the XTR kit I have a chance.

Soooo...scored myself a X0 Type 2 on eBay.
Finally being able to have the two RD's side by side.
The X0 has:
Carbon outer cage, different bolts that hold the parallelograms together (maybe Ti?), more machining on the outer parallelogram, more machining on the hanger portion.
The main body that houses the clutch, pulleys, and inner cage looks to be the same.
So all that adds up to about a 10 gram difference.
I did replace the stock steel limit screws and b-tension screw on the X9 with aluminum X0 ones. So that did save a few grams. So a stock one will be slightly heavier.

My new bike came with an X9 Type 2 and I'm not impressed. Could not get the thing to shift properly, turned out the clutch mechanism was way too tight and jerky. Good news, you can back it off. Bad news, because of the design there is little chance of it staying that way.
In my opinion the clutch design chosen for these dérailleurs is stupid. I'll be swapping for Shimano fairly soon.

Not sure what to tell ya. I've been using my X9 for the past year and its been great. I'm running Zee on my Pivot and thinking about switching to X9 and selling the Zee.
The shifts feel a lot more positive on the Sram than the Shimano.
Took me all of 10 mins to install the X0 and dial it in.
What I do like about the Shimano is that it sits closer to the frame.

I prefer the feel of Shimano shifters actually, personal preference I guess or maybe just what you're used to.
I assume that at least some of the X9 dérailleurs out there do work! ;0) Maybe even a lot of them but there sure are a fair few people with unhappy tails. Don't get me wrong, people have problems with Shimano, clutch bands breaking on their dérailleurs for instance. It's not like Shimano only make perfect products. It just seems to me like the balance tips in their favour a bit.
The ZEE looks like a great dérailleur, I was going to buy one but they only do it in short cage so I can't use it on a double. Probably just buy a Deore or SLX.

XO Type II has cartridge bearing pulleys, X9 Type II has plain bearing (bushing) pulleys. XO (Type 2.1) plate & pulley tolerances are tighter out-of-the-box than either of my two previous X9 Type IIs.

I don't think the type of bearings in the pulleys makes muck difference, if any. Cartridge bearings in there seem overkill as the plastic teeth will wear out long before the bearing irrespective of what they are.

macming and RS VR6 asked for objective differences between models.
On my first X9 Type II, a combination of lateral pulley play and grabby Type II clutch contributed to the chain walking off the lower pulley and wedging between pulley & cage. Note pulley teeth are unworn.

I can't see play in the pulley causing that. Sticky clutch, yes. I've ran very worn and loose dérailleurs and I've never seen that happen. In fact Shimano top pulleys have lateral float designed in. That looks like a combination of crap clutch and crap cage/pulley design to me. If the teeth are not worn there is no way the bearing, of whatever type, should be worn enough to allow that. It's the design itself that has let that happen.
Quite fortunate you didn't rip the dérailleur off!

Not in my two Type2 RD's. Both had same pulleys equipped with sealed industrial bearings. Zee had bushing pulleys, now it has Tacx T4060 pulleys which are better than SRAM ones.

I've worn the teeth down to nothing on Shimano pulleys but the ceramic bearings were still fine. I really don't see any need for a cartridge bearing in there considering all it does.

Having pulleys which have proper bearings keep RD shifting as expected even when pulley teeth are very worn out. And bushing bearings get very restrictive when soaked in wet mud etc.
Each their own recipe. My MTB gear newer gets anything ceramic bearing wise, more likely stainless.

Your jammed up SRAM looks very new and clean though...
