This is a potentially controversial topic, so let’s all stay curious and play nicely. I’ve switched from Peloton at the beginning of the Pandemic to Kickr in 2021. On Peloton I was following the Power Zone Pack challenge and raised my FTP from 180 to 302W in just over a year (I checked the Peloton …

[image] sudarkoff: But a 30% decrease warrants at least a question. Most of us don’t think it is a real 30% difference. I am fairly that certain you have too many differences in variables to make a proper comparison. If you can define the exact conditions of both tests in great detail, that…

[image] mcneese.chad: This is why Resistance or Standard mode and actual bike shifting are recommended vs ERG which sets & caps the effort. Makes a ton of sense. I’m more of a sprinter and VO2max workouts have always felt too easy in ERG.

[image] mcneese.chad: The info shared already points to the likelihood that we have apples & oranges in tests here. That’s very fair! A lot has changed. P bike is not super accurate, easily could have been up to 10% off, which at 300 means 30 whole watts. And for my most recent ramp test I’m …

[image] mcneese.chad: And to this point, not a single person thinks ERG is the root cause / issue here. So, let me try to repeat what I’ve heard so far to make sure I understand: The signal that lets the AT know whether the workout was too easy for me is the survey response. So if I answer…

[image] sudarkoff: The signal that lets the AT know whether the workout was too easy for me is the survey response. So if I answer “easy”, AT will adapt my plan accordingly Correct, AT looks at the power you produced, compared to the targets, and then combines your survey response to determ…

Sean has been the one answering these questions and has never dissected the over power questions between trainer modes or how it’s achieved. If there was a difference, I’d have expected him to state it. Baring that, I see no reason to question the impact difference on the trainer mode or how you e…

I get what you’re saying. But it’s super simple. AT is not looking at the WI setting at all. It’s comparing Actual Power to Target Power (at 100% WI according to FTP at the time of the workout). WI got mentioned initially as an answer to the perceived limit that there was no way to exceed power t…

It is based on numerous discussions with TR since March 2021, with heavy bouts back whenever I attempted a super pass and did not get results I expected. If you want more, I’d suggest you email them at this point.

I personally have noticed a 10-20w drop in sustainable power at threshold with erg mode… but only if using the small chainring and large gear. If I use the big chain ring and a small gear the difference goes away. I think the difference is due to higher fly wheel speed with the latter gearing. I can…

I’ve noticed that too. It was causing me to not perform as well on the hills on group rides. So I’m now training exclusively in the lowest gear (small chainring, big sprocket). Side benefit—it’s much quieter too!

Not sure if you have gotten any info from TR, but there is a question and very short answer from Amber related to this discussion. More detail would sure be helpful, but this seems pointed in the direction I mentioned.
