Just put a deposit on a Trail Pistol, and while I wait I need to figure out my drivetrain. GG is apperently out of Sram 11spd whcih was my first choice due to having a handful of spare parts already. That leaves either Xo or Gx Eagle or 11spd XT, 12sdp XTR is a bit out of my budget at the moment. I give zero fucks about the 50t cog, their Shimano drivetrain comes with a 46t cog and 42t has served me just fine. Weight is somewhat important, but between XT and Xo there's only a 1/10 of a pound difference, likely due to the carbon cranks on the Eagle set-up. The $405 cost difference between the two is pretty significant, but either way I'm within budget. Having never run either I don't have a particular preference, but hate fiddling with derailleurs constantly. My favorite part of my X01 11speed drive train has been the complete lack of maintenance. What say the Monkey? Which one will likely annoy me the least?
