Doing structured workouts in erg mode with a largish power change, eg 130w to 350W and I have hit a a problem. I have experienced a delay BEFORE the power starts to transition. This happened with my Direto smart trainer in both Zwift workouts and with the Elite MyEtraining software. The delay occurs both when power rises and when it is due to fall. I have found it massively disruptive to trying to do a structured session with short sharp power changes.
It did not happen with TrainerRoad. I thought this was excellent. I am a convert. I was also curious why this was the case.
I have been tipped off by GPLama and other sources, that the reason you do not have this problem with your structured workouts is that you anticipate the change and so send the power change signal a few seconds early so that the delay is minimised. Nice one. Neat solution guys. Love it. and it works. It is much better with TR and the Direto.
However, here is my problem… I am using an Elite Direto which seems to have a delay of 3-4 seconds and a slow transition. I am frustrated with this device. So, I am considering swapping to a Kickr Core. I am told by those who understand this problem that the delay before the power starts to change with a kickr is more like 1-2 seconds. And the transition is quicker. That is great. I am almost sold on this… but…
…my question is, if you apply a consistent adjustment to all trainers, does this end up being too early for the kickr core? Or do you adjust the anticipation of the power change depending upon the turbo (or brand) or whatever.
Or to put it another way, am I going to hit a different problem - that of the transition starting early? Or is this a known issue that you manage successfully from trainer to trainer.
I hope this makes sense? Cheers Phil
