4MX Dual Steel/Aluminium sprockets are designed and tested at the highest level.
New dual ring design gives the ultimate sprocket performance, reduced weight thanks to a 7075-T6 aluminium centre and long lasting teeth life thanks to the high carbon steel outer.
Dual steel/aluminium sprockets also feature a hexagon drive interface between the inner and outer ring, this is revolutionary technology for sprockets and maximises drive between the two parts and reduces the force on the rivets to zero unlike the competition.
Designed to outlast standard aluminum rear sprockets and is much lighter than steel rear sprockets
