Question: is this compatible with SRAM X0?
Document: Very impressed with the quality and looks. Can't beat the price for what you get. Used them with 2011 Specialized Stumpjumper with SRAM X-9 components.
I used this pulley to replace a bottom (chain tension) pulley in SRAM XO derailleur. I bought this one because I broke the old pulley (don't ask me how, I don't know). I don't think plastic vs. aluminum really matters but this was one the cheaper options plus red color is a nice touch.
Answer: yes
