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.
