![]() ![]() Anyone out there know how the erg actually measures wattage? Is it through a strain gauge or other method? I use a powertap on my bike and it is a little frustrating not to have accurate feedback on the erg in terms of what a watt 'costs'. My 'problem' with the erg is that I think the measuring of watts is way off. if my FTP (for an hour) was 300w, and I did a workout at an average of 250, the IF is. What I did was derive my FTP in watts as close as I could and then just plugged in intensity factors depending on what the percentage of FTP was for a workout.
