Will X-9 Short Cage work with 11-34T

Just want to make sure and check everyones experience. I got an X-9 short cage with 11-26 cassette and 36T single chainring front with chainguide. If I want to go up to a 11-34 cassette, and obviously lengthen the chain, will the X-9 short cage work in that setup? What has been your experiences with this setup? Thanks to all who chime in.

 

Yeah I run a x-9 short cage with my 36t and 11-34 cassette. No problems here

 

I run the same cassette in a 1x9 setup with a short cage and I have no problems with it.

 

For a 1x9 you can run short cage. 2x9 a medium cage. And a standard xc 3 ring run a long cage.

 

depends on the bike and how the rear suspension travels. If on a hard tail or a shorter travel bike you should have no problems. Some of the longer travel bikes tend to "grow" a bit as they go through their travel and thus pull a lot more on the drivetrain requiring a bit more "stretch" of the chain.

On my DH bikes I run an X-9 short cage with an 11-25 cassette and a 40t ring up front. Years ago I ran an 11-34 cassette with no problems.

 

For a Full on Techy type answer....No a short cage x9 will nmot work with a 34 tooth cassette.......the max tooth for that deraielr is 32. Thats Srams answer.

Now for a real world answer

Sjo n got the general answer..... but as DBD pointed out, it is a general answer, you have to take into account suspension growth.

 

yes it should work, unless you ride a single pivot or something with a ton of growth

 

Most people don't really understand what a derailleur actually does.
For what it's worth, here the best thing I've ever read on what a derailleur does and how you select the correct size: http://forums.mtbr.com/showthread.php?t=205890

 

I don't see why not. mine works fine on my reign with an 11-32, and that has a 2 link growth at full travel.

if you're worried about it, just get the 11-32 and pedal a bit harder. it'll be lighter too

 

for everyones info, its for an IH Sunday. I just wanted to pedal uphill a little better (when needed of course). I do not know if there is excess chain growth on that frame, but I presume not.

 

That's not SRAM's answer, from the SRAM Tech Manual:

 

Thats very interesting, the Manual I have in the garage says different, then agian its three years old, and the info may have been updated since then.

It could be as simple as Sram made a small mod to the derailer in the past years as well, the short cage one I had that came with the manual was pretty damn noisy when in the 34.

 

Download early and often.

Did you use the B-Tension screw to back the pulley away from the cassette?

 

I was always told to run a long cage on a 3 ring setup and from the articles above i can know see that is the safe thing to do. Thanks for the explanation and hopefully I will remember it at the right time.

 

I run a sram med cage on a 1x9 set up...in 32/32 it is noisy. Small cage I cant imagine sounding better.

 

Of coarse... In fact it was maxxed out, I should mention its teh bike I took to Barnetts with me, everyone there decided the same thing as well.

 

Interesting, now I'm curious if they made a change to the short cage in '08 or if there is a functional difference between the XO and X9.

 

Just installed the PG990 11-34 cassette and it all works just fine. No added noises. I have '08 X-9 short-cage and handle the larger cassette just fine, shifting was perfect didn't have to adjust a thing.

Now I have a PG970 DH 11-26 cassette for sale.
