I have done all of my indoor training on my elite nero rollers. I love them. I use the ERG mode and have no issues with anything except standing sprints. I can stand only for about 10 seconds. But I have poor bike handling skills and intentionally got rollers to improve my cycling skill. I figured that if I was going to be pedaling for hours at a time, I might as well develop some bike handling skill and core strength.
any updates with with your roller? Are you using the nero with a powermeter and/or external cadence sensor? My setup works with a some lag in torque. I would like to improve my setup to get a more direct regulation of the torque.
