Good shifting, easy set up, but durability is questionable and requires adjustment more than Shimano XT has. The pivots seem to loosen up after time and then require more frequent adjustment to shift smoothly

Pros: easy installation and initial adjustment

Cons: durability

Would Buy Again: No
Would Recommend: No

sram x9 rear.

I have used this unit in both the mid and long cage version and am pleased with each. shifting is crisp and low effort. not as refined as the new shimano units but they take a beating.

Pros: ease of setup , and consistent function. very tough.

Cons: strong unit does not break away on impact . i bent my hangar.

This is a great derailleur. Shifts are clean and crisp and it's pretty light.

replaced the xt shimano

I replaced my xt shimano with this derailleur and cannot figure out why shimano cannot build a better derailleur for the price. This one shifts great and was cheap.

Pros: Great shifting, cheaper than shimano. dependable, and strong

Cons: none

Performance of the XO without the price tag. It shifts smooth and is a noticeable difference from the X9. If you don't care about a couple more grams this is a much better value than the X0.

Pros: Durability, smooth shifting and performance.

Cons: None

Great derailleur, poor cable nut positioning.

Great RD that is just like years past except one glaring problem, the cable fastener bolt is in a very hard to reach place that makes installing and maintaining a pain.

Pros: Great shifts, good price.

Cons: Cable retaining bolt placement is awful.

SRAM quality at reasonable price. Was using Shimano components for years until I purchased SRAM Force group for road bike. I've been "making the leap" for my mountain bike components.

Pros: shifts great. Easy setup and installation.

Sram X.9 Shorty

Great product. Crisp shifting (I run 1x9 and am still a GripShift holdout) Light. No need to step up and put out the extra dough for X0. Not that X7 is bad either... X7 is just very heavy when compared to the X9.

Pros: Avail. in Short Cage. Light. Great shifting.

Cons: Can't think of any.

Quick shifting and durable. Why spend money on X0 when X9 is just as good?

Pros: Quick, durable, short cage has great range

Cons: None.

I run a full X9 drive train and the shifts are always crisp, fast, and reliable with this derailleur. Seems to be very strong as it's been banged into rocks and hasn't given me trouble.

Great Derailleur

I had just snapped my 9.0sl in half (rock in the chain on a muddy ride), and wanted a medium cage derailleur. The X-0 was a bit too pricey for a replacement on an old bike. This worked perfect. Installation was very simple. It doesn't seem to shift quite as well as well as the 9.0sl did, but it's not much of a difference.

Pros: Easy Install, great shifting, great price.
