SRAM X9 Type 2 Rear Derailleur 2013
The SRAM X9 Type 2 adds the Roller Bearing Clutch to a normal X.9 derailleur to deliver maximum drivetrain stability, even through rough terrain. This clutch eliminates bounce and chain slap without sacrificing precision. Clutch is self-lubricating, maintenance free, uses needle bearings, and comes factory calibrated from SRAM.
This unit provides quiet trouble free long term shifting. The clutch eliminates chain noise and slap. It's so good I put the same on my Cyclocross bike.
I picked this up because I was converting my FS 29er to 1x10, and wanted a clutched rear derailleur to help my new wide/narrow ring keep the chain where it was supposed to be. This was an upgrade from and X.7 that I never had trouble with, but the first thing I noticed was how smooth (nearly unnoticeable) shifts were with this thing installed. The second thing I noticed when attacking a rooty section of a local trail, was that I couldn't hear my chain slapping around anymore. Lastly, it's well worth pointing out that I haven't dropped a chain with this in place, even riding trails as notoriously rocky as Reddish Knob.
I had great hopes for this derailleur but it broke on the very first ride. The piece the derailleur cage mounts to is plastic and it cracked. No broken chain or foreign object, it just jammed up and broke My previous derailleur was a Shimano XTR that lasted for 13 years in the exact same riding conditions and severe countless broken derailleur hangers. That derailleur is still in better condition than my new X9 I would not recommend this derailleur or any SRAM drivetrain components to anyone unless they have the money to replace components every ride.
Have had this derailleur on my bike for about 2 months and have not yet dropped a chain on rough terrain shifts smooth and fast.
it's not top of the line but it performs like it. Quick, quiet and accurate along with a build quality that is top notch, this is a great derailleur!
Got this for my 1x10 build and I love having a clutched derailleur! I never have chain slap and it makes riding single track so much more enjoyable. Its not worth buying XO because all you're doing is shaving a few grams for double the price and all it takes is one rough encounter with mother nature to foul up your derailleur forcing you to replace it. I do however run an XO shifter pod, and I always get sharp responsive shifting from the setup.
Hey everyone, I don't review very many products because they often don't warrant it, but this is one component upgrade that has made a significant difference in my performance. Besides losing that every annoying chain slap, being able to focus on the trail ahead, and enjoy the rustle of the leaves as I rush over them; this products shifts superbly. I have it couple with the X9 shifter and have not had any problems even after numerous wipeouts. Of course I have to make the occasional barrel adjustment due to cable stretch, but that is it. Rest assured that you will not be disappointed with this shifter. Happy trails
Smooth shifting and reduces chain slap, which is very important with a carbon frame.
This derailleur works great! Shifts smooth and reduced chain slap to almost none. An affordable way to go with a 1X10 setup. XO technology with out the associated cost. I highly recommend it.
This derailleur is great bang for buck. The clutch eliminates chain slap and keeps the entire drivetrain quiet. An X0 doesn't have much different than the X9 besides a few less grams and a carbon cage. Get the X9-Type2 and never look back.
