Wonder on what level the "XRAY" 8 speed series falls? The centera grade was barely useable, never touched a SRAM x.0 / Attack series before.
i've replaced the twist grips on the X0 twist shifters a couple times, since they get gummy and turn to Goopy messes... replacement twist grips are $20 Each.... other than that, they work great, for twisties... basic old "Grip Shift" twisties do the same thing, and the grips don't turn to goop....

X0 trigger shifts/derailleurs work well, but are "Clunky" when you shift to smaller gears...
Clah.. CLUNK!
