Learn MoreThis complete flywheel assembly features an increase in inertia mass that smoothes power delivery.
Flywheels are measured by inertia weights because the effect of the weight differs depending on where it is in relation to the center of the crank. So a 4 ounce and 6 ounce weight might have the same effect depending on where they are positioned in relation to the center of the crank.
