@IvyAudrain : Just a quick suggestion… on the TrainerRoad articles, it would be nice if a footer or header said something like “Last Updated 03 April 2021” so it would be clear to the reader if the posted information is generally up-to-date.
As an example. I assume its all up to date, but I don’t really know. Sometimes new stuff gets announced in the forum before the ‘articles’ are revised.
(I am just now — after years with TR, playing with in-ride switches between ERG/resistance because of my new SB20 smart bike, and finally decided to look at this particular article)
