AFAM Sprockets S49 520 All RM+RMX+DRZ+SOME DR

AFAM steel rear sprockets are all CNC machined and produced in C45 normalized steel with induction hardened teeth.
An harder layer on the teeth reduces wear on sprocket and chain drastically and ensures a longer life span.
Executed in silver (zinc plated) or black (electrophoresis) for a long lasting protection against corrosion.
The normalized steel prevents the sprocket from micro cracks in the material
