Rated 5 out of 5 by Best rear derailleur Nice product to upgrade your derailleur... The best! 30 October 2013
Rated 5 out of 5 by Excellent My SS copy of this derailleur weights 166 gramms (but you still can shave its weight by replacing steel bolts with titanium ones). My derailleur was involved in road accident (the car struck rear wheel of my bike) and was dragged over asphalt, but it is still working properly!!! That's unbelievable. 17 April 2012
Rated 5 out of 5 by Dura-Ace Dura-Ace,it's so good at what it does, changing gears fast and smooth, looks so cool, matt gun -metal carbon, team up with front mech, and 7900 levers and your winning ! 08 August 2011

Answer: 
Shimano recommend using only 10-speed components together to ensure shifting performance.

It is not recommended to run this derailleur with a 9-speed drivetrain.

Answer: 
Yes,this will work perfectly with 9 speed.The lever pulls the cable to move the mech.I have used 10 speed mechs on 9 speed systems and have never had a problem.
