CNC machined from aviation grade 7075-T6 alloy the MTX Zero Alloy Rear Sprockets are your go-to option for the lightest possible sprocket solution. Constructed with self-cleaning mud grooves to increase the life of both your chain and sprocket. Computer designed weight reduction holes make the MTX Zero 66% lighter than the steel equivalent (model dependent) while maintaining maximum strength and durability. The anodised finish provides a factory look while preventing additional wear to the sprocket.
