I’m currently using a Tacx Vortex with TrainerRoad and recently purchased a set of Favero Assioma pedals. Have been using them for around three or four weeks now and have no complaints with them…very quick and easy set up and seems to be reliable (so far anyway).
Have a query though on optimal way to use with TrainerRoad workouts…i’ve been using Tacx Vortex without power meter pedals for around 9 months now and have been used to the steady nature of the power fluctuations (ie. when an interval kicks in, the trainer takes around 5 seconds to shift power from recovery power to interval power but when it gets there, the power is consistent and feels that way too…all I need to do is pedal).
However, when using the pedals with the Vortex, the power fluctuates up and down. My understanding is that the output power is coming from the force through the pedals and that the Vortex is reacting to that force and then adjusting the resistance in an attempt to keep the power within targeted power. Is that correct?
My issue is that sometimes my output power remains stuck above or below target power for long periods (upwards of 30s) of an interval resulting in average interval power being above or below target. Believe this is to do with small changes in cadence…can anyone confirm?
I wasn’t too concerned about this because I was of the view that this would even out over time and in any case it would be more realistic and in line with how power feels out on the road. However, i’m coming up to doing a ramp test again soon and starting to think that it may skew results below what i am capable of if the power is held below what the target power is supposed to be at each stage of the ramp test. Am I right in thinking this?
Or does anyone have any more optimal set ups?
