I use power2max on all my bikes (including road) but you lose some options for cranksets. I didn't care for how finicky the Garmin pods were, I used to calibrate and repair avionics equipment so I'm not unused to touchy equipment (I just don't want it on my bike).
Edit: The power2max is a 144bcd for the track though it's the Rotor3d track spider on the road arms so the Q is different than you might suspect - this surprised me when I got the set and think it's worth mentioning.
