I am using the Tacx smart trainer. It connects up ok and displays what it should and Zwift happily changes resistance on hills and reports my watts somewhere around where I would think they would be for the work I am doing.
However, the resistance it changes to on steeper slopes - say 4%+ - is not very realistic. I am dropping only a couple of cogs on the rear to go up those hills where I would normally drop a cog on the front too (I am heavy and hills are a killer - I have my correct weight in Zwift so I assume it would do the require calculations).
I do the hillclimb on 2 cogs down on the rear. The trainer can give much more resistance as I have played around with it with the Tacx app. I have been into settings and set the slider for difficulty up to Max but that didn’t make a noticeable difference.
Is there going to perhaps be an ability at some point to scale up the difficulty where there seems to be a mismatch like this?
