Rear sprocket RFX Pro Series EN 300 4T FI ES - 520

The RFX Pro Series Armalite sprockets are designed and tested at the highest level by the best racing teams from the World and British Championships.

The two-ring design ensures maximum gear performance, reduced weight thanks to the 7075-T6 aluminum center, and long tooth life thanks to the high-carbon steel outer part.

Armalite gears also feature a hex drive between the inner and outer rings, which is a revolutionary technology for gears and maximizes the drive between the two parts and reduces the force on the rivets to zero unlike the competition.

Features of the Pro Series Armalite Gears:

• CNC 7075 Aerospace Aluminum Inner Ring
• HCS outer ring
• Position of the hexagonal disc between the inner and outer rings
• CAD designed profile for ease of use.
• New style mud clearance channels to reduce wear.
• The rigid construction increases torsional strength.
• Colored anodizing for a factory look on the bike.
