This complete flywheel assembly features an increase in inertia mass that smoothes the power delivery. Helps get power to the ground and keep your momentum up through corners and tricky situations. Easy to install, allowing you the opportunity to change flywheels for different types of riding. Increases inertia 58% over stock.

Note: Flywheels are measured by inertia weights because the affect of the weight differs depending on where it is in relation to the centre of the crank. A 113g and 170g weight might have the same affect depending on where they are positioned in relation to the centre of the crank.
