Moose Offroad Hard Rear Sprocket - Parts (Ref. 1211-210-45-13) – Machined aluminium crown designed for cross and enduro use. Made from 7075 T651 with additional heat treatment, it limits deformation while maintaining an optimal tooth thickness. 100% machining: no stamping or grinding, for a consistent tooth profile and precise chain/tooth contact.
Designed to provide optimal tooth thickness and maximum contact between the sprocket and the chain, this crown is aimed at cross and enduro riders looking for a lightweight and precise drive component. It allows for easy adjustment of the gearing according to your style and terrain needs, without compromising the transmission geometry.
