This is a quick one.
As a temporary fix to the Stages cadence problem (my previous post), I went ahead and tried the new Garmin cadence sensor to see if that could offer an interim solution to my problem. Like Stages it is based on an accelerometer. Below is a screen capture from data of a 10 sec roller rev-out. The sudden drop off in the end is a result of focusing too much on the screen of the Garmin instead of the action at hand, and dropping off from the rollers. This was not an exhaustive test, just trying out something new… which then ended back in the store.
