I was already running a Rotor set up, so easy conversion to this power meter. This paired easily to my Garmin head unit for power meter function. I reused the Rotor chainrings that I already had been using. Everything went together as the instructions stated, just get your spacers correct and check for adjusting your front shifter throw. Rotor power app is a little wonky but works for realtime data to check your left/right power. Very interesting to see the difference in power between legs and how they are working across the pedal stroke. I may now do more research into the Q rings.
