I am using an Elite Qubo Fluid trainer in the classic speed/cadence set up.
I was wondering if someone could tell me how the zPower curve for this trainer is determined.
There seems to be quite a significant difference in resistance between the start of a training and after ca. 20 min. of cycling. With more resistance at the start (fluid still ‘cold’, at room temperature) and less resistance after warm up (fluid has become hotter, and therefore less viscous).
So my question is, at which temperature is the power curve of this trainer determined? Or, if that is too specific, should i trust the wattage at the beginning of the training or later on when the fluid has been heated?
Many thanks, Tom
