Hi Chaps,
I just installed an X9 rear mech, which is pretty awesome for quietening the drivetrain noise, even if you dont notice the noise now, you'd notice the absence.
Anyway.... when compressing the rear end, the chain tightens slightly, causing a noticeable clunk, as the cage is pivoting.
It feels like the bearing in the clutch is overtorqued, so that it's a bit notchy.
You'll pull on the mech by hand, and it'll not move, then it'll jerk a bit, then jerk a bit more.
Is this what everyone else's is like? and did you find a remedy, or did it slacken off over time?
Cheers

they are a bugger to move by hand, hard to say if I've had what you discribe, not as often I don't think.
Its only noticeable if you sit into the travel, or you pedal hard, and slow out of the saddle.
Just a bit odd, I'm going to see if I can slacken off the interface to the bearing....
I noticed that too when I'd fitted mine. I've no idea if it still does it as I've never noticed it when riding. I'd very strongly suggest that you do no more than dribbling a little lube into the interface between the cage and the mech knuckle before you have ridden it a few times. I'll bet that it's fine and you'll not improve it by trying to "fix" it when most likely, nothing is wrong.
Thats how they are - leave it alone 🙂
hmmm... I do have a noise at the moment, I'd been looking accusingly at the BB, after originally thinking it was the back end, its high strain pedalling, climbing... but I only get it when my mind is on other things. I shall pay close attention tonight.
Mines great. And it is a little clunky but isn't it just the clutching device doing it thang? Leave it alone. 🙂
OK Cool. I initially thought I'd sheared a shock bolt again, as it's a proper dull clunk like when a pivot is loose, or the bushing is worn on the shock.
As long as it's 'normal', I'll leave it be. Maybe some pivot grease in the interface to reduce stiction.
My noise was rear maxle, clutch mech not to blame. As to why I'm suddenly getting chain drops? Maybe I've just ascended to a higher level of Gnar... Fnar maybe?
Right so an update to this, as I've found a FIX! 🙂
On the clutch mech, there's a little black plastic button, covering the roller bearing (inside the Type2 Roller Bearing writing). You can prize this off with a stanley knife.
This reveals a T55 socket, undo this.
this no reveals a 4mm allen socket, which houses the bearing.
Remove the top pulley, by unscrewing the 3mm pivot bolt, this reveals another 3mm allen bolt.
Put a 3mm allen key against this, and put a 4mm allen key into the 4mm socket, and undo the 4mm socket - hold onto the 3mm key as underneath is the spring which can fly out if you don't butt up against it properly.
When you've undone the 4mm socket as much as you can, rock the 4mm key against it to pull out the whole 4mm socket.
Push a load of pivot grease inside the now exposed roller bearing, pop everything back together. And BOOM!
Smooth as ****. Suspension will actually work better, as it's not binding.
Essentially the bearing has been put together with no grease, so the bearing binds. Absolutely shocking.
Think prob a one off as not a prob I or others are having, but I'll be copying and saving that for regreasing in case mine ever starts doing it.
If you google it, there's a lot of people with the same problem. Looks like a defect to me.
It's a well sealed unit, so it shouldn't get worse, unless there's no grease in there to start with. which was what happened with mine.
You wont notice it if you have a hardtail either, as it's to do with chain stretch. Some suspension designs will not encounter the issue either.
If someone has an Mtbr account can you copy and paste my solution. Looks like some others had the same idea, but got it oh so wrong.
