Durability--I put 5 years on this item, including 4 major accidents requiring derailler hanger replacement.
Smooth--shifts like a dream--always.
Worry free--rarely needed adjustment, no matter how badly I abused it.
I guess I could grouse about price, but this came with the kit I ordered on my bike, so I didn't think about the specific cost of this item.
When I finally beat this one beyond recovery, I wanted to replace it with exactly the same item. But my LBS only had an X9 in stock and, being impatient, I went ahead and got that. After I put a season on the X9, I'll decide if it was worth the downgrade.
