I recently bought Favero Assioma Duo pedals and I am using them on my stationary bike. They are working great. Somehow I started having connection issues with my speed sensor. I use a Garmin 830. I use it on a stationary so i have to use old speed sensors with magnet. I switched brands to a Sigma Ant+ speed sonsor and it keeps disconnecting speed from Garmin 830. Both Garmin and Favero pedals are pretty new as well. How do get the speed sensor to connet once and for all?
