Advantages of aluminum sprockets Stage6
The extremely robust chainrings for mopeds with chain drive are CNC-milled from high quality aluminium and then anodized. They are made in Europe, no cheap product from Asia!
When developing the sprockets, Stage6 placed great emphasis on high durability and cool custom aesthetics as well as efficient power transmission. The sprockets are made of aluminium and therefore 40% lighter than comparable steel sprockets. This considerably reduces the weight or the load on the rear train and axle, which can lead to decisive advantages especially in racing. In addition, CNC-machined aluminium sprockets have more precise toothing compared to normal steel sprockets.
We recommend to change the whole chain drive at once, so replace sprocket and chain as well to increase the life of all components through even wear.
