• looking at solving 2 problems in one (I don't like changing powermeters between bikes and im one rear wheel short) with a second hand powertap pro 32 laced to a mavic open pro.

    is there any advice on making sure i'm not buying a dud?

  • I assume you're not buying in person? Get the seller to take a photo of the calibration results when calibrated the PM on their Garmin.
