I have a ZYCLE z pro, wheel on trainer. I produce more watts than the trainer sends to Zwift. I gotta live with that or there’s a way to bypass this and make it the real wattage?
How do you know which is the “real” wattage?
With a wheel-on smart trainer where power is measured at the roller, tire slippage can result in lower power readings. I don’t know that trainer but the usual advice is to use a trainer tire, inflated according to the manufacturer’s specification, and tension the roller according to the manufacturer’s specification. Perform spindown calibration regularly and ensure that tire pressure remains constant between calibrations.
