Did a comparison this morning between my garmin rally xc200 VS Tacx neo2t. Seems to be a 4-7 watt difference across all zones, the trainer being lower.
I know I could use the same power meter by swapping pedals every ride but I won’t.
I like having everything set up, so I don’t have to set anything up, the whole purpose of having a trainer is just for that, having everything ready.
After doing this comparison, it makes sense why I struggled on a suprathreshold workout last week. I probably should’ve done this a lot sooner.
Anyways, no big deal besides am I supposed to follow what Ai ftp gives me? Idk but I do know it’s not TRs fault for me not wanting to use the same power device. @Caro.Gomez-Villafane any advice using 2 separate power meters?
Honestly I need to stop being lazy and change the pedals over when I ride the trainer. That way I have 1 number to work from, it’s either that or do 2 separate ftp tests which doesn’t sound fun either
Unfortunately, in this case scenario, there is no good way to breach the power gap between your Tacx NEO 2T and your Garmin Rally XC200 since you won’t be using your pedals indoors.
However, the good news is that a 4-7 watt difference is actually not that bad and shouldn’t affect your ability to progress through your training or your AI FTP Detection since it uses a broad set of data points.
Ideally, you would use your Garmin Rally XC200 indoors with PowerMatch to bridge that offset and get the same power reading indoors as outdoors, BUT I personally wouldn’t change the pedals every ride, either! Seems like a pain and not worth it, especially if you have everything set up to just hop on. So I’d say relax and ride on!
Thanks for the reply!
I’m going to change the pedals regardless so I have 1 number to set my training zones. Worst case scenario if my pedals stop working, I can easily drop the ftp.
It doesn’t seem like a big difference but for those suprathreshold workouts it’s definitely harder than it should be. Either way, I have nothing but positive things to say about using TrainerRoad.
