Hi all, For those who have a bit more experience with these orange chips, is it recommended to secure these to the bike or alternatively to the ankle? For the Fast One this weekend, I had mine strapped around my right ankle, but it never registered a finish time for me. Now Strava//Garmin files have to be sent back and forth to prove my race completion. Techie from Racetec claims that if my leg was TDC (top dead center), some interference is created and my time would not have registered. Thanks.
