I recently bought a Tacx Flow. It has been calibrated and everything seems to work fine except the cadence when I’m in the lower gears. It seems accurate in the mid-upper to upper gears, but in the lower gears the cadence will jump around randomly from the 20’s to the 50’s when I know it should be reading between 60 and 70. My power in watts seems to be unaffected by this and seems accurate.
Any thoughts?
