During a ride, initially my Garmin hrm strap works perfectly. &nbsp;But 1/2 hour into the ride the HRM will suddenly drop to 76 beats per minute and stay there for the rest of the ride. &nbsp;I know my hr has not this dropped significantly due to soft pedaling, &nbsp;because I am usually about to vomit all over my bars.

I have changed the battery. &nbsp;

Anyone else having this issue? &nbsp;I am going to pick up a ant+ extension cord, but was wondering if it might be the Garmin HRM. &nbsp;

&nbsp;

Thanks.&nbsp;

The same thing happened to me.&nbsp;I also thought it was the battery.&nbsp;I changed the battery but have not tried it yet if it works. Using a garmin hrm strap to.
