SRAM X.9 10 Speed Rear Derailleur 2013
The new SRAM X9 10-speed rear derailleur brings you legendary SRAM X0 performance and reliability for less (and with only a slight weight penalty). It features Exact Actuation ratio technology for lightning-quick shift response and Di.R.T (Direct Route Technology) for top performance with minimal shifting effort. You can spend more if you want to, but if crisp, efficient gear changes are what you're after, X9 will suit you just fine.
This derailleur came stock with my bike. It is very precise, lilghtweight and easy to adjust. Nothing bad to say about it, good bang for the bucks.
I use this with a X7 shifter on my 1x10 and it's smooth and fast. I had a few crashes on the drive side and it still shifts correctly.
Have had it for almost a year now and it has been the best rear derailleur I've used. Easy to adjust and very reliable. I always recommend this derailleur.
I've been running this derailleur for a year now and it remains smooth and incredibly accurate and all 10 position. The clutch also changed from slopping around too much. I would recommend this product for anyone looking for an upgrade their derailleur.
The local shop tried to charge me $140 for this part! Thanks for the great price
I came from a shimano deore and the x9 is leaps and bounds better. The actuation of the arm is strong even after a year. The limit screw settings are very accessible and well labeled and actually adjust! I'm very pleased with the performance and the build quality of this RD.
Been using this derailleur for 3 months now. smooth shifting, crisp, easy setup. For the price its hard to beat. pair this with an x9 shifter and youll be very happy.
This is the first time I have tried Sram for my drivetrain. After doing much reading and comparison shopping I went with the X9 model to match the rest of my stuff. So far it looks great, carbon outer cage and black.
