Just changed my free hub from campag to shimano, before the hub was reading 515 and now it's reading 522 when I calibrate on my Garmin or Joule gps - anyone done this before and had a similar effect ? The hub is a 2012 pro hub. Obviously I cleaned the hub and applied a little grease to the pawls but did not expect the change.

    that's a difference of just over 1%... does it matter?

    True but the calibration value is getting close to the 512 +- 12 range

    Mine fluctuates from 508 - 515 depending on temperature. As long as the torque is at 0 its ok.
