Roll Down Calibration for CycleOps PowerBeam Pro Trainer
The CycleOps PowerBeam Pro resistance unit is calibrated at the factory. This enables it to ac-
curately measure power using similar technology as a PowerTap. Rolling resistance is calibrated
into each individual resistance unit, but can vary depending on tire type, tire pressure, clamping
pressure and other conditions. To obtain the most accurate results, follow these guidelines:
•
Perform the Manual Calibration described below.
•
Inflate tires to the rated pressure.
•
Attach the bicycle according to the PowerBeam Pro trainer user guide
•
Clamp the resistance unit to the rear tire according to the PowerBeam Pro trainer user
guide
•
For mountain bicycles, use smooth tires. Knobby tires are noisy and contribute to inac
curacies.
