Review on High-Performance SRAM GX Trigger 10v Rear Shifter 2016 - Smooth and Precise Shifting Experience! by Tutan Dennard

My 9 year old SRAM X7 rear derailleur has finally died. I don't need to buy a new bike as the 2012 custom enduro I have rides like new. But the X7 exploded. I wanted to buy XO for $140 then I saw GX. I'll reiterate what others have said here: the aluminum case looks a lot nicer than the plastic cases you're likely to replace. It was easy to install. Shifts are precise, crisp and light - very light on the thumb. Can't comment on durability yet, but so far it's amazing. And 100 less than XO.
