Pro Series Armalite Double Composite Sprocket - 520 51 Teeth by RFX

The RFX Pro Series Armalite double composite sprocket is designed for Cross and competition use, featuring a centre made from 7075-T6 aluminium and an outer ring crafted from HCS steel for enhanced durability. The Hex-Drive interface strengthens the connection between the rings and minimizes stress on the rivets, while the CAD-designed profile and mud-release grooves reduce wear in challenging conditions.

Design and Materials

• CNC machined 7075-T6 aluminium inner ring providing a lighter component and precise fit on the hub.
• HCS (high carbon density steel) outer ring for extended tooth lifespan.
• Hex-Drive interface between the rings maximizes power transfer and reduces stress on the rivets.
• CAD-designed profile to reduce mass while maintaining structural rigidity.
• New mud-release grooves limit clogging and reduce wear in muddy conditions.

Practicality and Features

• Remove the chain and rear wheel before installation to properly access the hub.
• Apply blue Loctite to each bolt during installation to secure the fittings.
