4 month ago I've bought edge 800 with GSC 10 speed/cadence sensor and started using it about 1 month ago. Initially everything worked fine. But then it started to show strange cadence values (it looked like it skiped some rotations). And then it stopped to show cadence data at all.
I would think it's a battery. But I started using it only month ago, and speed sensor is working fine.
Did anyone experince the same problem? Any suggestions?
