This is an interesting topic, to me it seemed that 85-95rpm target was more meant as “85+”, referring to riders who would not even make it to 85 or more.
Never had I thought it could mean that you could spin too quick. (Unless its one of these “climbing” sessions which require you to do down to 75rpm, partially standing and things like that.
Did I get it wrong? Can one spin too quick to get the intended training?
