Input Wheel Size?

Former Member over 9 years ago

Hi folks, 1st posting.
I've seen in the manual a list of wheel circumferences but cannot see how we tell the unit what size wheels we have. I appreciate that the unit has GPS/Glonass but I have the speed & cadence sensors fitted also. Do we need to input wheel size somewhere or does the 520 have some kind of self-calibration?
All help appreciated.

The 520 can auto-calibrate and that is the default mode. You can set it manually by going to sensor details in the menu. The sensor needs to be connected in order to change the setting.
