so on pinkbike i found an x0 short cage for 160$. my original plan was to get an x9 short cage from my shop, but thats gunna cost me 110$ plus tax. should i get the x0, or should i just get the x9? this is going on my dj bike, and yes i run gears, cuz this dj bike is used for everything, since i cant afford 2 bikes right now.
