"They had it in stock and the thing works like a charm."

So far so good...

"Once it's dialed in , it works as intended - not sure if it is a real step up from an SLX or a real step down from an XTR - but it is working well."

Upgraded from SLX

"Looks great and functions well. Feels a little more quicker engaging than the SLX I upgraded from. I also upgraded to XT shifter from SLX shifter so that might have something to do with it as well. Overall, it does what it's supposed to do well so no complaints."

Bomb Proof XT

"Although XT is not the top tier derailleur it sure performs as it. If you like quality but are mindful of a budget and want consistent reliability look no further than the XT line of components."
