Quote from: jhearrtot on June 17, 2026, 11:27:20 AMThe Magene is measuring before the drivetrain and the Saris is measuring after it. A small offset would be expected anyway, but what makes you think your trainer is more accurate?
I'm using a 1x oval chainring and had to adjust the slope from 100% to 97% after comparing the 3-second power readings with my Saris H3+ smart trainer.
