Can you set erg mode to adjust the resistence of a smart trainer so you can just concentrate on rpm ? I have been playing with the setting but nothing.

Which app? Which setting? What’s your setup? Check the FAQs and videos for help.

Xert mobile on Samsung 4s using a Tacx Bushido

Just trying to turn on erg mode will check FAQS

I have found the note on erg and slope in faq so will try that Thanks.

Also some material in the Zwift with Xert blog.

Cool Thanks.
