Took delivery of my kickr core today having previously owned a tacx flux s which packed up on me. Using the kickr today for my first ride I am unsure about the huge changes in power when changing gears.
I can’t remember the tacx being like this but there’s a huge diff in power between gears. So, big ring at the front, going along in 3rd hardest ring at back if I click up to 4th ring at the back there’s a drop off of about 100 watts and then it creeps up by about 30 watts or so over 10 seconds. Similarly, if I move from the 4th ring at back down to the 3rd ring at the back it jumps up about 100 watts then drops down 30 watts or so over 10 seconds.
Does this sound right? When riding on the flat if I’m in the 3rd biggest ring at the back I’ll push out approx 200 watts however if I moved into the 4th biggest ring at the back it’ll drop to about 105 watts then settle at 130 watts. This seems a huge drop to me between just 1 gear selection.
I’ve done the spin down etc. Did it a few times after test rides on zwift.
