RFX Pro Series Armalite sprockets are designed and tested at the highest level by top World and British championship race teams.
The 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.
Armalite 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.
