I replaced my wheelset this weekend on my commuter. I have found that when the speed and cadence sensors are paired to the Garmin it pauses and resumes all the time. It was so annoying on the commute in that I turned off the sensors.. I know it is not the GPS because when sensors are turned off it does not do it. I have also used it on another bike and it does not do it as well. I think it is the speed sensor messing up..

Could I have messed something up switching the speed sensor from one hub to the other? They are both on the rear wheel does that matter? I wiped it down with a paper towel to take some of the road grime off of it. (but should that matter considering it has been ridden in the rain?

is there a way to reset the speed sensor? how long should the battery last?

any advice?
