im looking to get my hands on a xtr double drivetrain. My plan is to run a 42/30 up front and run the 11-36 casseste in the rear. i'm setting it up on a hardtail 29er with a chainstay length of 17.72. my question is about the rear derailler. should it be the mid cage or the long cage? im assuming the mid is for double drivetrains and the long is for triple but i'm looking to run the 42 up front so im on edge before i order.
Any input would be greatly appreciated!
