RFX Pro Series Armalite aluminum double composite crown - 520

Product details

Armalite RFX Pro Series crowns are designed and tested to the highest standards by World Championship and British Championship racing teams.

The dual-crown design offers optimal performance, reduced weight thanks to a 7075-T6 aluminum center, and longer tooth life thanks to the high-carbon special steel exterior.

Armalite crowns also feature a hexagonal interface between the inner ring and outer ring, a revolutionary technology for crowns that maximizes transmission between the two parts and reduces the force exerted on the rivets to zero.

Features:

• CNC 7075 aluminum inner ring
• HCS outer ring
• Hex-Drive location between inner ring and outer ring
• Profile designed using CAD for greater lightness.
• New style of mud clearance grooves to reduce wear.
• The rigid design increases torsional strength.
• Anodized color
