Not sure what’s going on…
I use a Kinetic Road Machine and Vector 2s power meter. Always calibrate the same before each workout.
Example: Many workouts start with me hitting the correct power target for an interval at a reasonable 90rpm in a given gear, but then by the middle of the workout I have to spin 95+rpm in that same gear to hit the power target. When this happens I will often see the power numbers move 20 points above to 20 points below back and forth without me changing gear, rpm, or drag (dumb fluid trainer).
It doesn’t always happen, but when it does I end up blowing up and failing to finish.
Anyone have any ideas?
