Yes it does. A medium cage x.9 will only take up to a 32t on the cassette, while a long will do 34t. Brand doesn't really matter, but size does.Yup, cassette has nothing to do with it so you'll be good.
ive only got to play with the 07 x9 stuff and i can tell you that it isnt as nice as the 06 xo. one thing i wish the new x9 had but doesnt is the distinctive click that my xo shifter hasI think it was in the Pinkbike SRAM 2007 preview where they mentioned that the older X.0 lineup was turning into the X.9. 07 X.0 was further improved, and X.7 was effectivly taking up the older X.9 designs.
ive used several med cage derailleurs with 34t cassettes, no problems...Yes it does. A medium cage x.9 will only take up to a 32t on the cassette, while a long will do 34t. Brand doesn't really matter, but size does.
Hmm...Weird. I have been runing a X.9 long cage on a 2005 Sram Powerglide II (has a 34t big ring, it was free). I finaly got my hands a Med. Cage and it works fine. Rode a week in Whistler and never had shifting probs. in the high gear. A lot of other probs. but no shifting trouble.Yes it does. A medium cage x.9 will only take up to a 32t on the cassette, while a long will do 34t. Brand doesn't really matter, but size does.
According to Sram you should only run up to 32t on the medium, but if it works it works. I haven't tried this myself, so obviously you know better than I.ive used several med cage derailleurs with 34t cassettes, no problems...
This is actually a great solution for this type of bike. Most guys that i ride with, lock out the largest cog on DH bikes. That way I have an 11 - 28 cogset, it is all the gearing that i will ever need on this type of mobile.....so I've locked out the ability to go into the largest cog...not perf but working so far.
You must eat those things for breakfast. I go through 1 or 2 a season..take me forever to wreck a case.An unnamed distribuitor is holding a case of X9 short cages for me, but various formalities is holding those up. Should be awesome to have reasonably priced Sram deraileurs again, especially at the rate i go through them!
I think the whole line does. They just aren't made to look like weaved carbon via stickers like the X0s.The 07 x.9 short cage has a composite cage right?
Thats why I went back to Shimano. I went through probably 8 X-9 rear der. this year. I'm not made of money and I'd rather spend money on trips. I've had the same old Ultegra road der. for years. SRAM's quality is lacking.3 riders with the same deraileur on the DH, 2,4x and XC bikes that get ridden hard all the time will add up to a suprisingly large number of catastrophic failures and an embarssingly larger number of slopped out paralellogram pivots and bent parralellograms. Me and the 2 other riders in question are up to something like 32 broken deraileurs this season. It is just bad luck, like a season where it rains every race, as well are all 3 former bike shop managers who know how to set up deraileurs properly, and we check in with Sram regularly to make sure of it! No one tries to warranty the deraileurs, as there really are a finite number of parts that are allocated to Sram warranty every year, and it is not really fair for fast pros and semi pros to be taking all of those in lieu of less commited consumers....
But you can bend the x.7 back with a pair of pliers and it will keep working. I did this and rode the d until I broke the spring that returns the cage. It lasted many months this way. Then replaced it with an x.9...Notice the lower link/cable pinch bolt.
The X.9 is aluminum and reinforced. The X.7 is steel and bends if it hit's a rock. When it bends, it bends into the linkage and locks up the derailler.
x.9 is the only way to go.
As for shifters, the x.7 shifter is still solid, but don't skimp on the der.
But listen to what you said...But you can bend the x.7 back with a pair of pliers and it will keep working. I did this and rode the d until I broke the spring that returns the cage. It lasted many months this way. Then replaced it with an x.9...
