Pro Series Armalite Double Composite Sprocket Steel Aluminium - 520 52 Teeth by RFX

This double composite sprocket is designed for competition and Cross/Enduro training, featuring a centre made from 7075-T6 aluminium and an outer ring crafted from HCS steel, balancing lightweight construction with durability of the teeth. The Hex-Drive interface maximises the transmission between the rings and reduces stress on the rivets, ensuring reliable performance in demanding conditions.
