Pros: quality, durability, affordable, efficient

Cons: none

Recommendation: I have 2 of these, one is a clutch type, the other is not. I have never had a problem, I run them with the X9 shifter, always performs well. I highly recommend, great quality for the price.

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.
