    Niner One 9 crank question

    I have a 2016 One 9 that I run with a Bio-Centric II BB. I have been running a set of 175mm cranks and now I'm wanting to switch to a set of 170mm cranks.

    With this switch I would like to move to a Sram XX1 bb30 crank for the stiffness. The problem is when I add the threaded bb30 (Wheel MFG) bottom bracket into the Bio-Centric BB, the spindle is to short because of the added stack. (I do have the longer 106mm Spindle)

    Any suggestions?

    I thought about maybe going to a set of Rotor hawk cranks but unsure if I would get the same problem. (Race Face is not an option because i'm not going to put up with the creaking.)

    Can you exchange it for a XX1 GXP crankset?
