I use the Tacx Fortius with the Fortius software. When riding rlv's in mountains the resistance is gone when climbing and changing gears so the cadense is higher. When I change gear and thus lower the cadense the resistance is back. But that is not ok for my knees. When looking on the internet I read that this might be fixed with a firmware upgrade, it is a known bug. But..... I can't find the firmware because the support on Fortius is discontinued. Can anyone help? Does anyone have the lates firmware for the Forius motorbrake? I have the version with the white control-pad with the blue ring. And if you're interested, I have working fortius software.
