Model/Year: 2017

Pros: Shifts well Quiet Light Clutch

Cons: Expensive!

Recommendation: Bought this to replace an old x9 type 2 I ripped off on a log. Very expensive, 185.00. Didn't know GX was available so I purchased the XO. It's quiet and shifts great, but man that's too much for a part I'm just gonna break again.

Model/Year: 2011

Pros: Lightweight, shifts like a dream

Cons: Costly, easily broken...Ive replaced the carbon arm 3 times now...and only 9 speed....well, mine is.

Recommendation: Great der, just fragile and expensive.

Model/Year: 2009

Pros: Accuracy

Cons: None

Recommendation: I agree with most of the other reviews, and when paired with the X-0 shifters, whoa!!! like pulling the trigger on a gun! Next gear please!!!

Model/Year: 2012

Pros: Lightweight, snappy shifting, reliable

Cons: nothing

Recommendation: I went with the medium cage length and I'm glad I did. On top of the reliable shifting capability I almost never drop my chain (which happened a lot when I had a long cage derailleur).

Model/Year: 2010

Pros: shifts like a dream with XO shifters. plus looks good.

Cons: kind of expensive, but i got last years model on ebay for way cheap.

Recommendation: goog to go. just shop around for the best price.

Pros: Light. 1:1 actuation is precise and light. Carbon!

Cons: Very pricey. Fragile and prone to sticks and other trail debris.

Recommendation: Great buy for a racer or one concerned with weight.

November 30, 2009
Pros: Solid Shifting, Light Weight, Does Not care if the chaing is stressed or relaxed

Cons: Wass concerned about the Carbon cage, but it is still holding up GREAT

Recommendation: This set came on my Specialized Stumppy 29er and it has been flawless for well over a year. The shifts are incredibly PRecise, It doesn;t care if you are grinding up a hill or crusing down a flat twisty section, the gears just jump straight to what you call for. I have crashed several times into rocks and stumps etc.. I have bent my Hanger twice, and the derailure is still solid as it was when new. Coupled with the SX-9 shifters this set is great!

Pros: Light, strong, shifts witha snik

Cons: A little price but the best always is

Recommendation: many many many miles three bikes and still going

November 25, 2008
Pros: It's built to go with X.0 shifters for flawless performance. light and crisp. Best Xt/XTR alternative

Cons: Doesn't have the shadow design to stay out of the way of hazards like the Shimano RDs do.

Recommendation: You know on race day..your equip won't hold you back. Stellar component

September 19, 2008
Pros: Super shifting works flawlessly, lightweight and very little chain slap when using this unit

Cons: None

Recommendation: I recommend this for anyone who is racing or wants a flawless item....Not recommended if you plan to bash your bike around the main pivot bolt is aluminium and may not like the abuse.
