Model/Year: 2010

Pros: easy shifting
smooth

Cons: None so far

Recommendation: Works well and I have had zero issues with it.

Model/Year: Short Cage 2009 & 2010

Pros: - Lightweight
- Crisp and quick shifting
- Strong cage spring
- Cost efficient

Cons: - No clutch system... yet

Recommendation: Shifts smooth and works flawlessly. Never had an issue with it. The short cage does have a very strong cage spring which translates into a lot less shifting issues. My X9's have seen a lot of wear and tear and their shifting remains smoother and more precise any any of Sram's lower models.

For my money I don't see the point of upgrading to X0 as it's almost twice as expensive without a significant performance increase.

Pros: Sturdy, smooth shifts, looks good, inexpensive.

Cons: non yet

Recommendation: This is the derailleur that came on my Airborne Zeppelin Elite. With wrapped up twigs, mud, and some abuse, it still runs strong with no problems so far. Highly recommended.

Pros: Crisp Shifting
Looks good
Lightweight
Trouble Free

Cons: None

Recommendation: I have put my X9 through 3 seasons of racing and abuse and I haven't touched it! Shifts great all the time. Has a good solid feel when shifting between gears. Great product.

Pros: Looks good, resistant and precise

Cons: Nothing yet

Recommendation: Itīs an all terrain derrailleur, you can go anywhere and it wonīt let you down.

Pros: Medium Cage is much better than long cage. Works much better in technical terrain.

Cons: Nothing yet.

Recommendation: Great product for the price and it appears to be very durable.

Pros: Is a good all around rear Deraillur. I like the short cage though as you have more clearance in technical terrain.

Cons: Ghost shift.

Pros: Sram 1:1 is always precise and crisp. Stronger than the X0 and more resistant to stick hits.

Recommendation: Dependable durable derailleur. For people who don't like the fragility of the X0 but love its shifting.

Pros: Very strong, accurate shifting.

Cons: Nothing.

Recommendation: Dependable. After owning Shimano derailleurs for years and having to replace broken xts all of the time I am happy with my x-9 and will never go back

Pros: great product at a great price

Cons: last to long,,how can I justify getting a cool new xo if this one never breaks!

Recommendation: mine has been had a hard life beat and bashed most of the logo is gone and it still works like it did when iy was new.

Pros: works great, as it should

Cons: none yet

Recommendation: smooth and dependable shifting. Mine has taken a beating and still continues to perform the same as the day i got it.

Pros: This is a great product--everything a RD should be.

Cons: None

Recommendation: 99% of the functionality of an X.0 at 40% of the price.

Pros: Works great, does what it is supposed to. not too expensive.

Cons: None for what it is.

Recommendation: Great rear mech that works well and is crisp shifting and looks clean.

Pros: Smooth shifting

Cons: Nothing so far.

Recommendation: To me, this is very close to the X-0. Just not costly. You will not be disapointed in this derailleur.

Pros: great derailleur, excellent shifting!

Cons: any derailleur can get busted up if you fall on it enough

Recommendation: love it! i need a new one though.

Pros: Quick shifting with the 1:1 action. Tough as nails and looks good too.

Cons: None.

Recommendation: Get this derailer if you like quick, crisp shifts all built into a rugged design.

Pros: works

Cons: none

Recommendation: Good bang for your buck, works well for a reasonable price.

Pros: 1:1, Durability, VALUE!!!

Cons: none

Recommendation: Couldnt be happier, as a testament, a couple rides ago saw me pick up a small log that hooked a spoke and made a full revolution around my wheel! It bent the derailer hanger (i didnt notice it till i got to the store) and it was out of position by more than an inch. It still shifted perfectly! Good stuff.

Pros: Nearly all the features of the X0 without the cost.

Cons: nothing

Recommendation: Wonderful shifter works great and very little chain slap with this compared with the shimano line up of derailleur's

Pros: Very stylish and strong and hold up very well through my aggressive style riding. Once fine tuned, shifting is top notch & fluent. Great value also.

Cons: None

Recommendation: For anyone

Pros: Crisp shifting. Great design. Durable.

Recommendation: Going one step higher than this seems ridiculous for the to me, but I understand if you have a ton of money to burn or if you just want the most expensive stuff on your bike, then you would pass up the X-9s and go for the X-0s. The X-9 system is great and I have not damaged, replaced, or been dissapointed with either sets I have owned (one newer, one older). Crisp shifting and very reasonably priced. Great shifting. I can't justify paying mucho $$$ more for a little less weight and a little more show. I've ridden the X0s several times and never have regretting decknig my rides out with X-9 series.
