- the 520 initially with the sensor on Bike 1;
- "unenable" the sensor on the 520 but leave it in my drop down list
- pair the 520 with the sensor on Bike 2
- "unenable" the sensor on the 520 but leave it in my drop down list
And then simply select the relevant sensor (i.e. enable it) depending on which bike I am riding?
Or will the 520 only allow itself to be paired with one cadence sensor?
