One-Way Clutch Bearing
The BikeErg uses a one-way roller clutch to engage the flywheel during the drive phase. Slippage occurs when the internal rollers or sprags fail to wedge against the outer race, often due to thickened grease in cold temperatures or fatigue of the internal leaf springs. Replacing the bearing restores the mechanical 'bite' required to transfer torque from the belt drive to the flywheel.

Flywheel Hub Assembly
Since the one-way clutch is press-fit into the flywheel hub, the housing can become scored or damaged during a clutch failure. Replacing the entire hub assembly ensures the mating surfaces for the clutch rollers are within factory tolerances, preventing immediate recurrence of the slipping symptom.

Poly-V Drive Belt
While less likely than a clutch failure for a 'no resistance' symptom, a severely glazed or stretched Poly-V belt can slip on the drive pulley under high torque. If the friction coefficient between the belt and the pulley grooves drops below the required threshold, the belt will slide rather than rotate the flywheel assembly.
