Not sure if I’m suffering from a technique issue, settings issue or equipment issue. During longer VO2 intervals my target power starts to fall off and the harder I pedal the more it falls and I end up going from my target 90rpm up to 110 to remotely keep power on target. It’s a bit better with smaller front ring and a bit more resistance, but the last quarter of my interval always turns into a downward power slide as I fight ERG mode. Higher the target power the worse the issue.
Today I switched over to manual resistance for the last few intervals and I was able to keep my power on target with just 3-5rpm increase and 1-2 gear shifts.
This made me wonder if during VO2 ERG intervals that I may still need to shift gears to keep the power on target? Anyone have suggestions, ideas to try?
