Hi all, first time poster.
Recently upgraded my old dumb trainer to a Tacx Flux S mid range smart trainer. Have noticed that when I start at the beginning of a session that the power output at x cadence reduces between the start and end of the run, e.g.
Start - 85rpm - 140w
End - 85rpm - 115w
(In erg mode)
Figures aren’t exact but hope they illustrate the point, it is as significant as 20w+ though which seems odd…
Any insight to this would be great?
