A few posts recently on big cog vs little cog in erg mode and different feels and power.
I have done a few interval workouts now and recorded the workout using my trainer in TR and then separately from my stages LS to my Garmin.
Results show that for intervals which are say 350 watts it will always show around that number within TR, but from the Garmin it can vary a lot depending on the gear. If in the small gear at the front middle back it will generally be 25-30 watts lower and sometimes more. If it’s in the big front middle back it can match the 350 but my cadence then affects it. For example if cadence is 100 it’s roughly right but less and the power is less. I try to keep the cadence smooth and let the power catch up so to speak so no sudden surges but still the crappy results. This is all further exaggerated the higher the power. Yesterday’s intervalsincluded some at 400 watts which in Garmin were way off.
I’m thinking that this is limiting me in most HI workouts as unknowingly my watts are actually less than what’s prescribed and I’m not being pushed hard enough during these hard efforts (even though in TR it’s telling me that they are)
I’m using a Tacx flux and tempted to upgrade to a neo. I just want erg mode on the trainer to take care of the exact power requirements without me thinking about changing gears, certain cadences etc.
Any thoughts or advice welcome.
