For about the last 2 months I have been dealing with problems with the cadence function on my computer. Sometimes the cadence will go to 0 or it will be half or a third of the true cadence. This usually happens when I am pushing hard. When it started, it was only doing it on hills. But now it does it on flat sections if I am pushing hard enough. I am thinking it is the battery, but I'm not sure, and couldn't really figure out what to search for in the forum.
Anyone have any ideas?
