My Kickr Core recently gave me a FTP if 307 while the pedals gave me 286. When doing other workouts/races/rides (on TrainerRoad and Zwift) the power reading is consistently lower coming from the pedals.
I have ensured they are correctly calibrated and I’m aware of the power match option.
It seems weird that the Kickr is reading higher though (normally the other way around) so I used the DC Rainmaker power analysing tool, and it shows that my right pedal and Kickr are actually pretty close but the left pedal reads 5-20w less than the right & Kickr.
After finishing rides my left/right balance is always very similar 51/49, 48/52 etc.
I’m not quite sure what to make out of what the analyser tool has shown, if anything, so I thought I’d ask here?
It just seems weird that the right pedal and Kickr track closely but the left is lower. Could there be an issue with the left, or is the fact that the right and Kickr are close just a co-incidence and the left/right difference is ‘normal’ (My left leg being weaker) and I will need a 3rd power meter to really see if it’s the Kickr or pedals that are reading wrong (given the overall power reading is outside the 2% accuracy range? I have a stages on my mountain bike so I could put that bike on the trainer and use the Duo pedals, but given the Kickr is left only I wonder if this will be of any help in terms of accuracy?
