Probably a question that gets asked all the time, forgive me if it is redundant. Which power reading should I use on Sufferfest - The one from my bike’s PM or the Smart Trainer PM?
I recently installed a Cycleops Powertap C1 power meter on the bike I have on my Cycleops Magnus trainer and connected to Sufferfest. The readings from the bike PM vs the trainer’s PM are almost 20 watts different, fairly consistent from low to high output with the trainer’s numbers always lower.
I did try starting a workout today using the bike’s power meter on Sufferfest, and it connected just fine and the readout was steady, but the trainer didn’t provide feedback despite being in ERG mode so I switched back to the trainer’s power meter.
I would assume that I would want to use the bike’s power meter numbers for training since that’s what I will be using outside, but looking for your feedback and experience. Thanks
