Rear sprocket designed for enduro, the Moose Offroad Hard - Parts sprocket provides a lightweight and precise solution for your transmission. Made from aluminium 7075 T651 with additional heat treatment, it limits deformation while maintaining an optimised tooth thickness compared to standard 7075 T6 sprockets. Machined 100% (without stamping or grinding), it offers a consistent tooth profile for smooth engagement with the chain.
The choice of full machining ensures optimal tooth thickness to maximise contact between the tooth and the chain, contributing to predictable behaviour during accelerations and obstacles. Its careful finish and red hue provide a race look on your bike while remaining compatible with 520 pitch mounts.
