I have a 2018 KICKR and a Quarq PM on my mountain bike with an XX1 AXS drivetrain. Firmware is up to date, everything is installed correctly, the drivetrain is clean, and both devices are zeroed. Regardless of where on the cassette I run the chain, the PM reads 6% higher than the KICKR.
I can understand the 2% tolerance, but I’m concerned that these are off by 6%. Have you experienced this, do you have any suggestions? @Jonathan
