Replace your rear sprocket with a reliable ESJOT sprocket designed for demanding terrains. This 520 crown made of QSTE460 steel features a machined tooth profile using the Diamond Cut 2.0 process and a specific surface treatment that enhances wear resistance and performance under intensive conditions.
