PT300 Calibration Test

john979 · 2007-03-29T23:37:19+00:00

Weight = 28.625 pounds (weighed on accurate scale) Crank Length = 170 mm Gear Ratio = 3.65 (approx) Torque Reading = 52 inch-pounds Calculated Torque = 28.625X170/25.4/3.65 = 52.49 inch-pounds Not too bad since I did not level the trainer and I eyeballed the rollout by marking the flywheel with some electrical tape. Does anyone know the PT300 Pro's exact rollout? John
