Cheers for picking this up & replying @Bryce
When I say resistance mode I mean using the gears to adjust resistance. The Atom can run in 11 or 22 gear mode.
Zwift will let you turn erg on / off mid ride or interval
The wattbike app will let you turn erg mode on or off - this is done by a top of shifter button and would be great if TR could get this to work.
For example doing over/unders or short intervals, one click will take me to erg and then the next click drops me back into the gear I was last using… it’s a neat little intuitive function.
When using the wattbike hub the gear shifters will also increase or decrease watt output by 5 in erg mode, so 1 click will take you from 220 to 225 or 215 dependent upon which shifter you hit for on the fly micro changes.
